            {
                obj = null;

Answer 1

你必须联系你的活动，例如this.Load += new EventHandler(Page_Load);除非您设置AutoEventWireup="true"。

Answer 2

尝试在Button1_Click方法中添加断点。特别是，我希望抛出和丢失异常：

        catch (Exception ex)
        {
            ex.Message.ToString();
        }

什么都不做！向用户显示消息，或者将消息记录下来（可能是Trace.WriteLine(ex)）。

另外 - 不要将obj设置为null - 没有目的。

提交按钮不起作用
