ASP.NET使用存储过程插入数据

string strconn= ConfigurationSettings.AppSettings["dsn"];
//连接本地计算机的TMS数据库
SqlConnection cn= new SqlConnection (strconn);
cn.Open ();
//利用Command对象调用存储过程
SqlCommand cm=new SqlCommand ("contractadd",cn);
//将命令类型转为存储类型
cm.CommandType =CommandType.StoredProcedure ;
//往存储过程中添加参数
cm.Parameters .Add ("@TID",SqlDbType.VarChar);
cm.Parameters .Add ("@TCID",SqlDbType.VarChar);
cm.Parameters .Add ("@TPID",SqlDbType.VarChar);
cm.Parameters .Add ("@TBeginDate",SqlDbType.VarChar);
cm.Parameters .Add ("@TEndDate",SqlDbType.VarChar);
cm.Parameters .Add ("@TTotalMoney",SqlDbType.Money );
cm.Parameters .Add ("@TContent",SqlDbType.VarChar);
//给存储过程的参数付值
cm.Parameters ["@TID"].Value =tbx_tid.Text .ToString ();
cm.Parameters ["@TCID"].Value =ddl_tcid.SelectedItem .Value ;
cm.Parameters ["@TPID"].Value =ddl_tpid.SelectedItem .Value ;
cm.Parameters ["@TBeginDate"].Value =tbx_tbegindate.Text .ToString ();
cm.Parameters ["@TEndDate"].Value =tbx_tenddate.Text .ToString ();
cm.Parameters ["@TTotalMoney"].Value =tbx_ttotalmoney.Text .ToString ();
cm.Parameters ["@TContent"].Value =tbx_tcontent.Text .ToString ();
cm.ExecuteNonQuery ();
//关闭连接
cn.Close();
