Question

I have generic list … I am trying to convert it to a data table.

I am using below code..

private DataTable ToDataTable<T>(List<T> items)
{
        var tb = new DataTable(typeof(T).Name);

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

        foreach (PropertyInfo prop in props)
        {
            Type t = GetCoreType(prop.PropertyType);
            tb.Columns.Add(prop.Name, t);
        }

        foreach (T item in items)
        {
            var values = new object[props.Length];

            for (int i = 0; i < props.Length; i++)
            {
             values[i] = props[i].GetValue(item, null);

            }

            tb.Rows.Add(values);
        }

        return tb;
}

I need to add another column in that datatable, say StatusText.

There is already a column in that datatable called Status.

If this column is 0 then StatusText should be Active, or if it is 1 then StatusText will be Inactive

Like my code returns below table currently…

Id   Name  Status
------------------
1    Test   1
2    Test1  0
3    Test2  0

But, how can I generate table like below?

Id   Name  Status  StatusText
------------------------------
1    Test   1       InActive
2    Test1  0       Active
3    Test2  0       Active

Try this

DataTable dt = ToDataTable(your list); // Get DataTable From List

dt.Columns.Add(new Column("StatusText", typeof(string))); // Add New Column StatusText


//Iterate All Rows 
foreach(DataRow row in dt.Rows)
{
   //Check Status value, and set StatusText accordingly. 
   row["StatusText"] = int.Parse(row["Status"])==1 ? "InActive" : "Active";
}
