Question

how to extract DataTable or DataSet from Linq Query or List.
e.g I have linq query like this

MyDBpDataContext dcSp = new MyDBpDataContext();
dcSp.myProgrammSP().ToList();

I wrote an Sp which sends a Table as result and I have code which is already using DataTable So I want to convert this result in DataTable.

The result doesn’t exist as a DataTable at any point, so if you want it as a DataTable, you have to create one and copy the data into it.

Example:

DataTable table = new DataTable("Items");
table.Columns.Add(new DataColumn("Id", typeof(Int32)));
table.Columns.Add(new DataColumn("Name", typeof(String)));
foreach (Item item in items) {
  DataRow row = table.NewRow();
  row["Id"] = item.Id;
  row["Name"] = item.Name;
  table.Rows.Add(row);
}
