c# - How to convert a List into DataTable

Question

I'm getting values from another data table as input to list. Now i need to save those list values into another DataTable.

List:

List<DataRow> list = slectedFieldsTable.AsEnumerable().ToList();
foreach (DataRow dr in slectedFieldsTable.Rows)
{
    list.Add(dr);
}

New Data table :

DataRow newRow = tempTable.NewRow();
newRow["Field Name"] = fieldLabel;
newRow["Field Type"] = fieldType;

for(int gg =0 ; gg<list.Count; gg++)
{
    tempTable.Rows.Add(????);
}

I'm stuck here in adding up rows in to new data table.

Answer 1

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;
}
