This extension method helps you to convert linq Query results (Generic List) to Datatable.
The following code explains you how to call this extension method.
var result = (from order in db.Orders.AsEnumerable()
group order by order.ShipCity into rowGroup
select new
{
ShipCity =rowGroup.Key,
TotalOrders =rowGroup.Count()
}).Distinct().ToList();
DataTable dt =ToDataTable(result);
public static DataTable ToDataTable<T>(IList<T> data)
{
PropertyDescriptorCollection properties =
TypeDescriptor.GetProperties(typeof(T));
DataTable table = new DataTable();
foreach (PropertyDescriptor prop in properties)
table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ??prop.PropertyType);
foreach (T item in data)
{
DataRow row = table.NewRow();
foreach (PropertyDescriptor prop in properties)
row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
table.Rows.Add(row);
}
return table;
}
