Question

I am developing a project in SharePoint 2010.

My requirement is to get an empty DataTable but with column names in it from SharePoint List.

The .GetDataTable() method returns only if it has a value.

So basically I need a structure of the list in a DataTable.

Answer 1

This should give you an empty datatable if the GetDataTable does not retrieve column information.

DataTable _dt = new DataTable();

foreach (SPField spf in _lst.Fields)
{
   _dt.Columns.Add(spf.InternalName.ToString(), spf.Type.GetType());
}
