SQL存储过程的调用及写法

调用函数：

    public class SqlProcess
    {
        public int ReturnValue = 0;
        public DataSet ReturnSet = null;
        public SqlDataAdapter adapter = null;

        public SqlProcess(String proc,String uid,String pwd,String data,String ip) {
                uid = Regex.Replace(uid,@"[^w]*","");
                pwd = Regex.Replace(pwd,@"[^w]*","");

                SqlConnection conn = new SqlConnection(Config.DBConnString);
                conn.Open();
                SqlCommand sqlcmd = new SqlCommand(proc, conn);
                sqlcmd.CommandType = CommandType.StoredProcedure;
                sqlcmd.Parameters.Add(new SqlParameter("uid", uid));
                sqlcmd.Parameters.Add(new SqlParameter("pwd", pwd));
                sqlcmd.Parameters.Add(new SqlParameter("data", data));
                sqlcmd.Parameters.Add(new SqlParameter("IP", ip));
                SqlParameter returnParm = new SqlParameter("return", SqlDbType.Int);
                returnParm.Direction = ParameterDirection.ReturnValue;
                sqlcmd.Parameters.Add(returnParm);
                adapter = new SqlDataAdapter(sqlcmd);
                ReturnSet = new DataSet();
                adapter.Fill(ReturnSet);
                conn.Close();
                ReturnValue = Convert.ToInt32(returnParm.Value);
        }
    }
