.NET Core get array in array from config.json - .net-core

Question

I have an issue where an array object in my config.json is coming back as empty. In the following code, gridFields will come back as empty.
{"grids": [{
"name": "Grid1"
"gridFields": [
{
"Name": "Something",
"Label": "Something"
},
{
"Name": "SomethingElse",
"Label": "SomethingElse"
}]
},
{"name": "Grid2"
"gridFields": [
{
"Name": "Something",
"Label": "Something"
}]
}]
}
I have matching POCOs and made sure the names match up as follows.
public class Grid
{
public string name { get; set; }
public gridFields gridFields {get; set;}
}
public class gridFields
{
public List<gridField> GridFields { get; set; } = new List<gridField>();
public int Count => GridFields.Count();
public IEnumerator GetEnumerator()
{
return GridFields.GetEnumerator();
}
}
public class gridField
{
public string Name { get; set; }
public string Label { get; set; }
}
In my startup I have the following
public void ConfigureServices(IServiceCollection services)
{ services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
var config = new List<Grid>();
Configuration.Bind("grids", config);
services.AddSingleton(config);
}
The config.gridFields ends up holding no values. I have values for name, but not gridFields. Even if I make gridFields List it comes back null.
My question is if there is someway following this current code that I can get the data out of this array in array, or do I need to do something completely different. Why isn't .net core able to bind every object it comes across underneath the parent?

Answer 1

The example json misses a , after the name of each grid.
{
"name": "Grid2",
"gridFields":
[{
"Name": "Something",
"Label": "Something"
}]
}
You have a list of gridField directly under the Grid in the Json.
In the Code however you use another object, GridFields.
You should remove the gridfiels class and use a list of gridField in the Grid class:
public class Grid
{
public string name { get; set; }
public List<gridField> gridFields {get; set;}
}
