Convert List Object to DataTable Object

Sometimes ago, I was working in project and there are following scenario:

First Scenario: In this situation, I have to copy values from one class to another class. I am providing the following code snippet which is useful for this:

#region Deep Copy
/// <summary>
/// This method is used to copy values from one class to another class
/// </summary>
/// <param name="dst">Destination Class</param>
/// <param name="src">Source Class</param>
public static void DeepCopyShallow(this Object dst, object src)
{
    var srcT = src.GetType();
    var dstT = dst.GetType();
    foreach (var f in srcT.GetFields())
    {
        var dstF = dstT.GetField(f.Name);
        if (dstF == null)
            continue;
        dstF.SetValue(dst, f.GetValue(src));
    }

    foreach (var f in srcT.GetProperties())
    {
        var dstF = dstT.GetProperty(f.Name);
        if (dstF == null)
            continue;

        dstF.SetValue(dst, f.GetValue(src, null), null);
    }
}
#endregion

Second Scenario: In this situation, I have to convert list object to datatable object. I am providing the following code snippet which is useful for this:

#region ConvertToDataTable
/// <summary>
/// This method is used to convert list to datatable
/// </summary>
/// <typeparam name="T">Class Type</typeparam>
/// <param name="items">Class Object</param>
/// <returns></returns>
public static DataTable ToDataTable<T>(List<T> items)
{
    DataTable dataTable = new DataTable(typeof(T).Name);
    //Get all the properties
    PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);
    foreach (PropertyInfo prop in Props)
    {
        //Setting column names as Property names
        dataTable.Columns.Add(prop.Name);
    }
    foreach (T item in items)
    {
        var values = new object[Props.Length];
        for (int i = 0; i < Props.Length; i++)
        {
            //inserting property values to datatable rows
            values[i] = Props[i].GetValue(item, null);
        }
        dataTable.Rows.Add(values);
    }
    //put a breakpoint here and check datatable
    return dataTable;
}
#endregion

Note: The above methods are static and it can only be defined in the static class. Just provide the objects in this static method.

That’s it. Happy Coding!!
