c# - Passing datatable to a stored procedure

Question

I have a datatable created in C#.

using (DataTable dt = new DataTable())
{
    dt.Columns.Add("MetricId", typeof(int));
    dt.Columns.Add("Descr", typeof(string));
    dt.Columns.Add("EntryDE", typeof(int));
    foreach (DataGridViewRow row in dgv.Rows)
    {
        dt.Rows.Add(row.Cells[1].Value, row.Cells[2].Value, row.Cells[0].Value);
    }

    // TODO: pass dt
}

And I have a stored procedure

CREATE PROCEDURE [dbo].[Admin_Fill] 
-- Add the parameters for the stored procedure here
@MetricId INT,
@Descr VARCHAR(100),
@EntryDE VARCHAR(20)

What I want is to pass the datatable to this stored procedure, how?

Answer 1

You can use a Table Valued Parameter as of SQL Server 2008 / .NET 3.5....

Check out the guide on MSDN

Also, as there other options available, I have a comparisonof 3 approaches of passing multiple values (single field) to a sproc (TVP vs XML vs CSV)
