i want Replace بازي to بازی
var List = (from darkhast in Tbl_Darkhast.Where(d => d.Address.Replace("ی","ي").StartsWith( Address.Replace("ی","ي") ) )
select new
{
....
}
I think,You should write in select query
var List = (from darkhast in Tbl_Darkhast) )
select new Tbl_Darkhast
{
Address= darkhast.Address.Replace("ی","ي")
,Name = darkhast.Name
};
The distance and character displacement:
var List = (from darkhast in Tbl_Darkhast.Where(d => d.Address.Replace(" ", "").Replace("ي", "ی").Replace("ك", "ک").StartsWith(Address.Replace(" ", "").Replace("ي", "ی").Replace("ك", "ک")))
select new
{
....strong text
}
result is =>
var List = (from darkhast in Tbl_Darkhast.Where(d => d.Name_Moteghazi.Replace(" ", "").Replace("ي", "ی").Replace("ك", "ک").StartsWith(NameMoteghazi.Replace(" ", "").Replace("ي", "ی").Replace("ك", "ک")))
select new
{
Shomare_Darkhast = darkhast.Shomare_Darkhast,
Tarikhe_Darkhast = darkhast.Tarikhe_Darkhast,
Sharhe_NoeDarkhast = darkhast.TBL_NoeDarkhast.Sharhe_NoeDarkhast,
Mantaghe = darkhast.Mantaghe,
Hoze = darkhast.Hoze,
Block = darkhast.Block,
Melk = darkhast.Melk,
});
return (ObjectQuery)List;

I'm using ElarsticSearch 7.7 & NEST 7.7 and on my web page, I'm getting 9 search result documents per page. Even I'm showing the first 9 results on the page, I need to return some property values from all the results for side filtration on the web page.
Eg: if I'm searching "LapTop", my page will show 9 results on the first page. Also, I need to show all the "Manufactures" from all the search results. Not only manufacturers in the first-page result. Then customers can filter by manufacture not only display on the first page.
I have tried GlobalAggregation but it returns categories and manufactures only items in selected page.
public SearchResult Search(SearchType searchType, string searchQuery, int storeId, int pageNumber = 1, int pageSize = 12, IList<SearchFilter> requestFilter = null, decimal? priceFrom = 0, decimal? priceTo = 100000000, string sortBy = null, int totalCount = 0)
{
var queryContainer = new QueryContainer();
var sorts = new List<ISort>();
sorts.Add(new FieldSort { Field = "_score", Order = SortOrder.Descending });
switch (sortBy)
{
case "z-a":
sorts.Add(new FieldSort { Field = Field<ElasticIndexGroupProduct>(p => p.SortValue), Order = SortOrder.Descending });
break;
case "a-z":
sorts.Add(new FieldSort { Field = Field<ElasticIndexGroupProduct>(p => p.SortValue), Order = SortOrder.Ascending });
break;
}
var aggrigations = new AggregationDictionary
{
{"average_per_child", new
AverageAggregation("average_per_child",Field<ElasticIndexGroupProduct>(d => d.Price))},
{"max_per_child", new MaxAggregation("max_per_child",Field<ElasticIndexGroupProduct>(d => d.Price))},
{"min_per_child", new MinAggregation("min_per_child", Field<ElasticIndexGroupProduct>(d => d.Price))},
{
"globle_filter_aggrigation", new GlobalAggregation("globle_filter_aggrigation")
{
Aggregations =new AggregationDictionary
{
{"category_flow", new TermsAggregation("category_flow"){Field = Field<ElasticIndexGroupProduct>(p => p.CategoryFlow)} },
{"manufacturers", new TermsAggregation("manufacturers"){Field = Field<ElasticIndexGroupProduct>(p => p.Manufacturer)} }
}
}
}
};
var searchRequest = new SearchRequest<ElasticIndexGroupProduct>()
{
Profile = true,
From = (pageNumber - 1) * pageSize,
Size = pageSize,
Version = true,
Sort = sorts,
//Scroll = Time.MinusOne,
Aggregations = aggrigations
};

var searchResponse = _client.Search<ElasticIndexGroupProduct>(searchRequest);
var categoryFlowsGlobe = new List<string>();
var allAggregations = searchResponse.Aggregations.Global("globle_filter_aggrigation");
var categories = allAggregations.Terms("category_flow");
foreach (var aggItem in categories.Buckets)
{
if (!categoryFlowsGlobe.Any(x => x == aggItem.Key))
{
categoryFlowsGlobe.Add(aggItem.Key);
}
}
}
This is the exact use case for Post filter - to run a search request that returns hits and aggregations, then to apply filtering to the hits after aggregations have been calculated.
For Manufacturers, these can be retrieved with a terms aggregation in the search request - you can adjust the size on the aggregation if you need to return all manufacturers, otherwise you might decide to return only the top x.

I have used linq to store data, below is the code:
var result = (dynamic)null;
var serviceData = (dynamic)null;
var userData = (dynamic)null;
/****Linq 1*****/
serviceData= dtPasscode.AsEnumerable().Select(m => new
{
ACCOUNT_ID = intAccountId,
SUB_ACC_ID = m.Field<string>("ACCOUNT_ID_ALIAS")
});
/**Linq 2**/
userData = DisplyCustomerDetails(Convert.ToInt64(strSubAccountID));
result = serviceData.Concat(userData);
And another linq through function:
/**Function**/
System.Data.EnumerableRowCollection DisplyCustomerDetails(Int64 intAccountId)
{
var result = (dynamic)null;
/** Data Display if no service avaiable **/
IAccount_BL objAccount_BL = new Account_BL();
Customer objCustomer = new Customer();
DataTable dtCustomer = null;
int intErrorCount = 0;
objCustomer.Account_Id = Convert.ToInt64(intAccountId);
dtCustomer = objAccount_BL.GetCustomerDetails(objCustomer, ref intErrorCount);
objAccount_BL = null;
objCustomer = null;
if (intErrorCount == 0)
{
if (dtCustomer != null)
{
if (dtCustomer.Rows.Count > 0)
{
result = dtCustomer.AsEnumerable().Select(m => new
{
ACCOUNT_ID = intAccountId,
SUB_ACC_ID = m.Field<string>("ACCOUNT_ID_ALIAS")
});
}
}
}
return result;
}
I wanted to join both the result of Linq1 & Linq2, I tired Concat & Union, getting below error
'System.Data.EnumerableRowCollection<<>f__AnonymousTypea>' does not contain a definition for 'Concat'
To Concat both enumerables must of the same class; you cannot use anonymous classes. Define a class that has the two fields and change the code to Select them.
Also, don't use ... = (dynamic) null; just assign the variable directly
var serviceData= dtPasscode ...
var userData = DisplyCustomerDetails ...
var result = serviceData.Concat(userData);
I need to delimite and categorize below json value
for ex : "sub3[+]888800" sub3 is category code and 888800 is element of category.
["sub3[+]888800","sub3[+]100000","06[+]888800","06[+]100000"]
i need to result like that
sub3 -> 888800, 100000
06 - > 888800, 100000
List<string> seledItems = this.ResetSeledItems();
this.litDebug.Text = Newtonsoft.Json.JsonConvert.SerializeObject(seledItems);
var json = this.litDebug.Text;
var strs = JArray.Parse(json);
// process the delimiter
var items =
from str in strs.Select(x => (string)x)
let idx = str.IndexOf("[+]")
select new
{
tag = str.Substring(0, idx),
data = str.Substring(idx + 3)
};
// do the grouping
var grps =
from item in items
group item by item.tag into grp
select new
{
tag = grp.Key,
items = grp.Select(x => x.data)
};
foreach (var grp in grps)
{
string tag = grp.tag.ToString();
for(int i=0;i<=3 ; i++)
{
string item = grp.items.ToString();
}
}
How about the following:
// prepare the data
var json = "['sub3[+]888800','sub3[+]100000','06[+]888800','06[+]100000']";
var strs = JArray.Parse(json);
// process the delimiter
var items =
from str in strs.Select(x => (string)x)
let idx = str.IndexOf("[+]")
select new
{
tag = str.Substring(0, idx),
data = str.Substring(idx + 3)
};
// do the grouping
var grps =
from item in items
group item by item.tag into grp
select new
{
tag = grp.Key,
items = grp.Select(x => x.data)
};
// output
foreach (var grp in grps)
Console.WriteLine(grp.tag + " -> " + String.Join(", ", grp.items));
with these using clauses:
using Newtonsoft.Json.Linq;
using System;

I have a linq query like below:
public IQueryable<vmEmp> GetEmp(int crewid)
{
var dt = new EmpEntities();
var e = from t in dt.tblEmp
where (t.CrewId == crewid)
select new vmEmp
{
Id = -1,
Crew = t.crewid,
Name = t.Name,
Address = t.Address
};
return e;
}
I hope can make the Id auto decrease by 1 till end of the employee.
like first's Id is -1, second's is -2, third is -3 ...
How to do that here? Thanks a lot
If this was LINQ-to-objects, you could use this overload of Select:
var dt = new EmpEntities();
var e = dt.tblEmp
.Where(t => t.CrewId == crewid)
.Select((t,index) => new vmEmp
{
Id = -index - 1,
Crew = t.crewid,
Name = t.Name,
Address = t.Address
});
But EF doesn't suport this, because the indexer can't be translated into SQL. So you need a work-around:
var dt = new EmpEntities();
var e = dt.tblEmp
.Where(t => t.CrewId == crewid)
.Select(t => new
{
Id = 0,
Crew = t.crewid,
Name = t.Name,
Address = t.Address
}
.AsEnumerable() // Continue in memory
.Select((t,index) => new vmEmp
{
Id = -index - 1,
Crew = t.Crew,
Name = t.Name,
Address = t.Address
});
Side note: it's recommended to put dt in a using construct.
Use a counter variable and decrease it for every record while you project it to your custom POCO.
public IQueryable<vmEmp> GetEmp(int crewid)
{
int counter=0;
var dt = new EmpEntities();
//load the items to a list of anonymous type
var eList = from t in dt.tblEmp
where (t.CrewId == crewid)
.Select(s=>
new { Id = 0,
Crew = s.crewid,
Name = s.Name,
Address = s.Address
}).ToList();
var e=eList.Select(x=> new vmEmp
{
Id = --counter,
Crew = x.Crew,
Name = x.Name,
Address = x.Address
});
return e.AsQueryable();
}
