如何使用C＃

Question

--Stored程序

ALTER PROCEDURE [dbo].[Test]    
@USERID varchar(25)    

AS    
BEGIN     
SET NOCOUNT ON      
IF NOT EXISTS Select * from Users where USERID = @USERID)   
    BEGIN       
     INSERT INTO Users (USERID,HOURS) Values(@USERID, 0);     
    END 

值傳遞到存儲過程我在SQL Server 2005中這個存儲過程，並希望從C＃應用程序通過用戶ID。我怎樣才能做到這一點。非常感謝。

此主題在MSDN here中有詳細介紹。請參閱標題爲「使用與一個SqlCommand和存儲過程的參數」的一個很好的示例部分：

static void GetSalesByCategory(string connectionString, 
    string categoryName) 
{ 
    using (SqlConnection connection = new SqlConnection(connectionString)) 
    { 
     // Create the command and set its properties. 
     SqlCommand command = new SqlCommand(); 
     command.Connection = connection; 
     command.CommandText = "SalesByCategory"; 
     command.CommandType = CommandType.StoredProcedure; 

     // Add the input parameter and set its properties. 
     SqlParameter parameter = new SqlParameter(); 
     parameter.ParameterName = "@CategoryName"; 
     parameter.SqlDbType = SqlDbType.NVarChar; 
     parameter.Direction = ParameterDirection.Input; 
     parameter.Value = categoryName; 

     // Add the parameter to the Parameters collection. 
     command.Parameters.Add(parameter); 

     // Open the connection and execute the reader. 
     connection.Open(); 
     SqlDataReader reader = command.ExecuteReader(); 

     if (reader.HasRows) 
     { 
      while (reader.Read()) 
      { 
       Console.WriteLine("{0}: {1:C}", reader[0], reader[1]); 
      } 
     } 
     else 
     { 
      Console.WriteLine("No rows found."); 
     } 
     reader.Close(); 
    } 
}
