Get the column name from list

Question

I would like to fetch the column names from List. As I have a class

public class DetailView

    {
        public string SiteName { get; set; }
        public string ItemType { get; set; }
        public string AssetStorage { get; set; }
    }

and in some method in controller am filling the data into Session. Now I want to get the column names for some reason. Am putting my session data into that list.

List<DetailView> objgrdDtls = new List<DetailView>();
objgrdDtls = (List<DetailView>)Session["datasetVal"];

I would like to have the Column name. Pleas note by doing the below code i got the value of that particular column name. restult1 has the column value.

var result1 = objgrdDtls.Where(p => p.SiteName.ToLower().Contains(txt1));

But all i need is Column name. So how do i get that.

stringColumnname = objgrdDtls.get(columnaname => some filter)?

Is this is the way how to get column names? Not sure how to get the column name one by one? Thanks.

You can use reflection to get the column name. Here is the runnable example to get the column name of DetailView.

using System;
using System.Reflection;

public class DetailView
{
     public string SiteName { get; set; }
        public string ItemType { get; set; }
        public string AssetStorage { get; set; }


}

    public class Example
    {
        public static void Main()
        {
            DetailView fieldsInst = new DetailView();
            // Get the type of DetailView.
            Type fieldsType = typeof(DetailView);

        PropertyInfo[] props = fieldsType.GetProperties(BindingFlags.Public 
            | BindingFlags.Instance);


        for(int i = 0; i < props.Length; i++)
        {
            Console.WriteLine("   {0}",
                props[i].Name);
        }
    }
}

Var result1 will give the list of DetailView Objects which meet the condition "SiteName.ToLower().Contains(txt1)". It will not be a value. Can you please clarify what do you mean by column value. However, For selecting a particular column value, You can append ".Select(p => p.AssetStorage)".

Column value is the which it has the data in that, i mean say for example, there is a property SiteName for that property there would be data like 'INDIA'. Now i want to get the Column name ie, property name like 'SiteName', ItemType and AssetStorage which i have declared in class Detail View. – user3794063 Jun 22 '16 at 10:07
