存储过程

    ALTER PROCEDURE [dbo].[usp_User_Info2] @UserName VARCHAR(30)
    AS  
    BEGIN 
       SET NOCOUNT ON;

       INSERT INTO User_Info2 (UserName) VALUES (@UserName)   
    END   

C#代码:

protected void BtnUserNext_Click(object sender, EventArgs e)

  SqlConnection SqlCon = new SqlConnection(GetConnectionString());  
  SqlCommand cmd = new SqlCommand();   
  cmd.CommandType …
