Question

页面脚本继续运行，不显示消息＆＃34;您的请求已成功提交＆＃34;正如我在下面提到的那样。任何人都可以帮助我在这里失踪吗？

现在解决了。它在CreateMailItem（）中的Console.Read（）中出错。这就是为什么它永远不会回到Button1_Click1（对象发送者，EventArgs e）发布成功提交的消息。我省略了Console.Read（），现在CreateMailItem（）的执行完成，控件返回到Button1_Click1（对象发送者，EventArgs e），以发布成功提交的消息。

更新部分：

捕 { Console.WriteLine（＆＃34;插入失败＆＃34;）; //Console.Read（）;
            }

脚本消息未显示
