人气:0
想了解C#获取存储过程返回值和输出参数值的方法的相关内容吗,在本文为您仔细讲解获取存储过程返回值和输出参数值的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:存储过程返回值,输出参数值,下面大家一起来学习吧。

1.获取Return返回值

复制代码 代码如下:

//存储过程
//Create PROCEDURE MYSQL
//     @a int,
//     @b int
//AS
//     return @a + @b
//GO
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["LocalSqlServer"].ToString());
conn.Open();
SqlCommand MyCommand = new SqlCommand("MYSQL", conn);
MyCommand.CommandType = CommandType.StoredProcedure;
MyCommand.Parameters.Add(new SqlParameter("@a", SqlDbType.Int));
MyCommand.Parameters["@a"].Value = 10;
MyCommand.Parameters.Add(new SqlParameter("@b", SqlDbType.Int));
MyCommand.Parameters["@b"].Value = 20;
MyCommand.Parameters.Add(new SqlParameter("@return", SqlDbType.Int));
MyCommand.Parameters["@return"].Direction = ParameterDirection.ReturnValue;
MyCommand.ExecuteNonQuery();
Response.Write(MyCommand.Parameters["@return"].Value.ToString());

2.获取Output输出参数值

复制代码 代码如下:

//存储过程
//Create PROCEDURE MYSQL
//     @a int,
//     @b int,
//     @c int output
//AS
//     Set @c = @a + @b
//GO
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["LocalSqlServer"].ToString());
conn.Open();
SqlCommand MyCommand = new SqlCommand("MYSQL", conn);
MyCommand.CommandType = CommandType.StoredProcedure;
MyCommand.Parameters.Add(new SqlParameter("@a", SqlDbType.Int));
MyCommand.Parameters["@a"].Value = 20;
MyCommand.Parameters.Add(new SqlParameter("@b", SqlDbType.Int));
MyCommand.Parameters["@b"].Value = 20;
MyCommand.Parameters.Add(new SqlParameter("@c", SqlDbType.Int));
MyCommand.Parameters["@c"].Direction = ParameterDirection.Output;
MyCommand.ExecuteNonQuery();
Response.Write(MyCommand.Parameters["@c"].Value.ToString());

C#接收存储过程返回值:

复制代码 代码如下:

     public static int User_Add(User us)
     {
         int iRet;
         SqlConnection conn = new SqlConnection(Conn_Str);
         SqlCommand cmd = new SqlCommand("User_Add", conn);
         cmd.CommandType = CommandType.StoredProcedure;
         cmd.Parameters.AddWithValue("@UName", us.UName);
         cmd.Parameters.AddWithValue("@UPass", us.UPass);
         cmd.Parameters.AddWithValue("@PassQuestion", us.PassQuestion);
         cmd.Parameters.AddWithValue("@PassKey", us.PassKey);
         cmd.Parameters.AddWithValue("@Email", us.Email);
         cmd.Parameters.AddWithValue("@RName", us.RName);
         cmd.Parameters.AddWithValue("@Area", us.Area);
         cmd.Parameters.AddWithValue("@Address", us.Address);
         cmd.Parameters.AddWithValue("@ZipCodes", us.ZipCodes);
         cmd.Parameters.AddWithValue("@Phone", us.Phone);
         cmd.Parameters.AddWithValue("@QQ", us.QQ);
         cmd.Parameters.Add("@RETURN_VALUE", "").Direction = ParameterDirection.ReturnValue;      
         try
         {
             conn.Open();
             cmd.ExecuteNonQuery();
             iRet = (int)cmd.Parameters["@RETURN_VALUE"].Value;
         }
         catch (SqlException ex)
         {
             throw ex;
         }
         finally
         {
             conn.Close();
         }
         return iRet;
     }

C#接收存储过程输出参数:

复制代码 代码如下:

    public static decimal Cart_UserAmount(int UID)
    {
        decimal iRet;
        SqlConnection conn = new SqlConnection(Conn_Str);
        SqlCommand cmd = new SqlCommand("Cart_UserAmount", conn);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@UID", UID);
        cmd.Parameters.Add("@Amount", SqlDbType.Decimal).Direction=ParameterDirection.Output;
        try
        {
            conn.Open();
            cmd.ExecuteNonQuery();
            iRet = (decimal)cmd.Parameters["@Amount"].Value;
        }
        catch (SqlException ex)
        {
            throw ex;
        }
        finally
        {
            conn.Close();
        }
        return iRet;
    }
