从C＃代码的单个SQL查询中插入多行？

Question

I have multiple set of data to insert at once, say 10 rows.

My table has three columns: PlanId , MomEntryId and CreatedBy

Can I insert all 10 rows in a single SQL statement?

This is my Store procedure. How can I pass 10 rows values in SP. I need to validate that PlanId and MomEntryId too that it's value is greater than zero or not.

CREATE PROCEDURE SP_Document_Plan_Or_MomEntry_Insert
@PlanId int = null,
@MomEntryId int = null,
@CreatedBy varchar(20)  
AS
BEGIN
    if(@PlanId > 0)
    begin
        Insert into t_Document(PlanId,CreatedBy,CreatedDate)
        values
        (@PlanId,@CreatedBy,GETDATE())
    end
    else if (@MomEntryId>0)
    begin
        Insert into t_Document([MomEntryId],CreatedBy,CreatedDate)
        values
        (@MomEntryId,@CreatedBy,GETDATE())
    end
END
GO

Below is my C# code for passing parameters.

  cblCheckList.Items.Cast<ListItem>().ToList().ForEach(d =>
                    {
                        if(d.Selected)
                        {
                            momEntry.AddDocumentDetailForMomEntry(Convert.ToInt32(d.Value), Session["userId"].ToString());
                        }
                    });

and this is for Datalayer code.I use Enterprise library file for creating DbHelper class.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;

/// <summary>
/// Summary description for MOMGateway
/// </summary>
public class MOMGateway
{
    private MOMGateway()
    {
        //
        // TODO: Add constructor logic here
        //
    }

   ///
   /// This method perform insert operation in Document table
   ///
    public static int AddDocumentEntryforMomEntry(int momEntryId,string createdBy)
    {
        int i = Convert.ToInt32(DBHelper.GetDatabase().ExecuteScalar("SP_Document_Plan_Or_MomEntry_Insert",
                      null,momEntryId,createdBy));
        return i;
    }



}

Use User Defined Table Type for this purpose. You can pass the DataTable or your collection of object from C# code as parameter to your defined table type.
