You should use Table-Valued Parameters

Create a Sql Type for the table you will pass in

CREATE TYPE dbo.ScoreType AS TABLE ( ScoreID int, StudentID int, etc.... ) 

pass your datatable from C# code into the stored procedure using the above defined type

ALTER proc [dbo].[InsertIntoScore] 
( @DateReg datetime, @stdLastName nvarchar(50), @stdFirstName nvarchar(50), 
@Description nvarchar(500),  @tvpScore ScoreType) 
AS 
   .....
   INSERT INTO dbo.Score (ScoreID, StudentID, ....)     
   SELECT dt.ScoreID, @id, .... FROM @tvpScore AS dt; 

in c# pass the datatable in this way

SqlCommand insertCommand = new SqlCommand("InsertIntoScore", sqlConnection); 
SqlParameter p1 = insertCommand.Parameters.AddWithValue("@tvpScore", dtScore); 
p1.SqlDbType = SqlDbType.Structured; 
p1.TypeName = "dbo.ScoreType"; 
.....
insertCommand.ExecuteNonQuery();
