Answer 1

您應該使用Table-Valued Parameters

創建SQL類型爲表，你會通過在

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

在c＃使用上述定義的類型

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; 

通過從C＃代碼的數據表到存儲過程通過在數據表這種方式

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