Ok I have the following extensions I am checking in my code.
FileAttachments.FileAttachmentTypes fileAttachmentType = FileAttachments.FileAttachmentTypes.None;
The strings below in the conts are helled in a constants file
public const string wordExtensions = "docx;docm;doc";
public const string imageExtensions = "gif;tiff;tif;png;eps;raw;bmp;jpeg;jpg";
public const string excelExtensions = "csv;xml;xls;xlsb;xlsm;xlsx";
Which is then parsed down here
I am getting my extension from the File Info class as such
foreach (var fileAttachments in FormFile) {
if (fileAttachments.Length > 0) {
string filePath = Path.Combine(hostingEnvironment.WebRootPath, "Uploads");
var tennantId = GetCurrentTennantId().Result;
var settings = _context.SystemSetup.FirstOrDefault().UploadFolderPath;
string uniqueFilename = Guid.NewGuid().ToString() + "_" + fileAttachments.FileName;
string savedFileName = Path.Combine(filePath, uniqueFilename);
FileInfo infoFile = new FileInfo(savedFileName);
string extension = infoFile.Extension.Replace(".","");
Here I check the file extension Parameter above in the semi colan separated strings
if (extension.Contains(Constants.imageExtensions)) {
fileAttachmentType = FileAttachments.FileAttachmentTypes.Image;
} else if (extension.Contains("pdf")) {
fileAttachmentType = FileAttachments.FileAttachmentTypes.PDF;
} else if (extension.Contains(Constants.videoFormats)) {
fileAttachmentType = FileAttachments.FileAttachmentTypes.Video;
} else if (extension.Contains(Constants.excelExtensions)) {
fileAttachmentType = FileAttachments.FileAttachmentTypes.Excel;
} else if (extension.Contains(Constants.wordExtensions)) {
fileAttachmentType = FileAttachments.FileAttachmentTypes.Word;
} else if (extension.Contains(Constants.audioExtensions)) {
fileAttachmentType = FileAttachments.FileAttachmentTypes.Voice;
}
}
Types is just an area for categorizing them into tabs for front end display
public enum FileAttachmentTypes {
[Display(Name = "Microsoft Word")]
Word = 1,
[Display(Name = "Microsoft Excel")]
Excel = 2,
[Display(Name = "Image")]
Image = 3,
[Display(Name = "Voice Recordings")]
Voice = 4,
[Display(Name = "PDF")]
PDF = 5,
[Display(Name = "Video")]
Video = 6,
[Display(Name = "Evidence")]
Evidence = 7,
[Display(Name = "None")]
None = 8,
[Display(Name = "Notes")]
NOTES = 9,
[Display(Name = "Shared Case")]
SharedCase = 10,
[Display(Name = "Created Case")]
CreatedCase = 11
}
My Question is why is it not finding it for a word document of extension docx when its clearly there

I am having a hard time understanding what should be a simple task. I am now using EPPlus to help me with this task. However, I am at a point of where I can't track what is going on. (per the comment below and days of google searching) I'm trying to read in an excel file and pass that to my EF model. It breaks down at line 159 where I am trying to put in the values from the excel file but keeps coming across as null. However when looking at the values past line 159 they all have the correct information. I am not sure how to even track a bug like this.

I'm trying to create a self referencing object using linqTOsql mapping. So far, I am definitely in over my head. Here's the code I have:
[Table]
public class Category
{
[Column(IsPrimaryKey=true, IsDbGenerated=true, AutoSync=AutoSync.OnInsert)]
public Int64 catID { get; set; }
public Int64 parentCatID { get; set; }
public string catName { get; set; }
public string catDescription { get; set; }
internal EntityRef<IEnumerable<Category>> _category;
[Association(ThisKey = "parentCatID", Storage = "_category")]
public IEnumerable<Category> category {
get { return _category.Entity; }
set { _category.Entity = value; }
}
}
My fakeRepository is defined like this:
// Fake hardcoded list of categories
private static IQueryable<Category> fakeCategories = new List<Category> {
new Category { catID = 1, parentCatID = 0, catName = "Root", catDescription = "" },
new Category { catID = 2, parentCatID = 1, catName = "Category w/subs", catDescription = "" },
new Category { catID = 3, parentCatID = 1, catName = "Category no subs but now has subs", catDescription = "" },
new Category { catID = 4, parentCatID = 2, catName = "Zub Cat", catDescription = "" },
new Category { catID = 5, parentCatID = 2, catName = "Sub Cat", catDescription = "" },
new Category { catID = 6, parentCatID = 0, catName = "Another Root", catDescription = "" },
new Category { catID = 7, parentCatID = 0, catName = "Ze German Root", catDescription = "" },
new Category { catID = 8, parentCatID = 3, catName = "Brand new cats", catDescription = "" },
new Category { catID = 9, parentCatID = 8, catName = "Brand new cats sub", catDescription = "" },
}.AsQueryable();
I pass Category to the view like this:
public ActionResult CategoryTree()
{
IQueryable<Category> cats = genesisRepository.Category
.Where(x => x.parentCatID == 0)
.OrderBy(x => x.catName);
return View(cats);
}
The problem that I'm running into is that all of this compiles, but I don't get anything beyond the root categories. Model[0].category is returning null.
What is wrong with my self-referencing object?
Edit
I wonder if it's not working because I don't have a real linq-to-sql data context in my fakeRepository. If that's the case, is there a way around that? Can I can get this to work without a connection to a database?
Yeah, you hit the nail on the head. It's not working because you're using a fake repository.
Linq-to-Sql does all the wiring up for you and sets the related collections based on the properties (& their attributes) that you setup in your model.
I don't know how to accomplish this without a connection to the database because internal EntityRef<IEnumerable<Category>> _category; is completely foreign to me - I'm more of a POCO model type of guy.
After a quick google, I found this - How to: Map Database Relationships (LINQ to SQL)
Could you change your model to read:
[Column(IsPrimaryKey=true, IsDbGenerated=true, AutoSync=AutoSync.OnInsert)]
public Int64 CatId { get; set; }
[Column]
public Int64 ParentCatId { get; set; }
[Column]
public string CatName { get; set; }
[Column]
public string CatDescription { get; set; }
private EntitySet<Category> _ChildCategories;
[Association(Storage = "_ChildCategories", OtherKey = "ParentCatId")]
public EntitySet<Category> ChildCategories
{
get { return this._ChildCategories; }
set { this._ChildCategories.Assign(value); }
}
private EntityRef<Category> _ParentCategory;
[Association(Storage = "_ParentCategory", ThisKey = "ParentCatId")]
public Category ParentCategory
{
get { return this._ParentCategory.Entity; }
set { this._ParentCategory.Entity = value; }
}
Now because your ChildCategories is of type EntitySet<Category> (which inherits from IList<T>) you should be able to wire fake relationships up yourself.
So you could do something like this:
private static IQueryable<Category> GetFakeCategories()
{
var categories = new List<Category> {
new Category { CatId = 1, ParentCatId = 0, CatName = "Root", CatDescription = "" },
new Category { CatId = 2, ParentCatId = 1, CatName = "Category w/subs", CatDescription = "" },
//Blah
new Category { CatId = 8, ParentCatId = 3, CatName = "Brand new cats", CatDescription = "" },
new Category { CatId = 9, ParentCatId = 8, CatName = "Brand new cats sub", CatDescription = "" }
};
//Loop over the categories to fake the relationships
foreach (var category in categories)
{
category.ChildCategories = new EntitySet<Category>(); //new up the collection
foreach (var subLoopCategory in categories)
{
if (category.ParentCatId == subLoopCategory.CatId)
category.ParentCategory = subLoopCategory;
if (category.Id == subLoopCategory.ParentCatId)
category.ChildCategories.Add(subLoopCategory);
}
}
return categoies.AsQueryable();
}
It works in my head at least... :-)
HTHs,
Charles
EDIT: Re: Comment below about a null reference on _childCategories.
You could change the model to look like:
private EntitySet<Category> _ChildCategories = new EntitySet<Category>();
It is supposed to be null. You are getting all categories where the ParentId = 0 ... and you don't have a child with an Id of 0. So that seems right to me.
It is not showing any subcategories because it has no subcategories to show. Try this:
IQueryable<Category> cats = genesisRepository.Category
.Where(x => x.parentCatID != 0)
.OrderBy(x => x.catName);
The parentCatId needs to point to a valid CatId for it to be a subcategory. This query should get you all the categories that are subcategories.
