Convert a Generic List to DataTable

public static DataTable ToDataTable<T>(this IList<T> data)

{

    PropertyDescriptorCollection props = TypeDescriptor.GetProperties(typeof(T));

 

    DataTable table = new DataTable();

    for(int i = 0 ; i < props.Count ; i++)

    {

        PropertyDescriptor prop = props[i];

        table.Columns.Add(prop.Name, prop.PropertyType);

    }

    object[] values = new object[props.Count];

    foreach (T item in data)

    {

        for (int i = 0; i < values.Length; i++)

        {

            values[i] = props[i].GetValue(item);

        }

        table.Rows.Add(values);

    }

    return table;
