推荐答案

我敢肯定，这根本不是真的.

您无法证明事件已发生.这可能不是事件，而仅仅是事件处理程序，可以将其编写为单独的方法:您可以从其他地方调用它.

请执行以下操作:1)找到您的事件处理程序； 2)在Visual Studio中，单击其名称上的上下文菜单，选择并单击查找所有引用"；如果无法做到，请执行全文搜索.

它将找到您看到效果的原因.您找到它了吗?

I am sure, this is simply not true.

You could not proof your event occurs. This could be not event but merely your event handler which could write as a separate method: you call it from somewhere else.

Do the following: 1) locate your event handler; 2) in Visual Studio, click context menu on its name, select and click "Find All References"; If you cannot do it, perform full text search.

It will find you the reason of effect you see. Did you find it already?

感谢您的回复.

是的，它是Web应用程序.

和代码类似下面的内容

受保护的void Page_Load(对象发送者，EventArgs e)
{
//要在页面上执行的基本操作
}

受保护的无效btnUpload_Click(对象发送者，EventArgs e)
{
//其中的代码用于上传文件.
}

现在，每当刷新页面时，默认情况下都会调用btnUpload_Click并创建文件的副本.

Thanks for the reply.

Yes it is web application.

And code is some what like following

protected void Page_Load(object sender, EventArgs e)
{
// basic action to be performed on page
}

protected void btnUpload_Click(object sender, EventArgs e)
{
//Code inside this is for uploading file.
}

Now whenever I refresh my page, btnUpload_Click is called by default and it creates a copy of file.

看起来您无法清晰地表达自己的意思.看起来，一旦您使用上载按钮，然后每当您按F5键(执行刷新)时，同一事件就会再次触发(一个常见问题).
如果是这样，请查看此文章以寻求解决方法: ASP.Net中的刷新页面问题 [ ^ ]

Looks like you are unable to express yourself clearly. It looks like once you use upload button and then whenever you press F5 (do a refresh), same event triggers again (A common issue).
If so, have a look at this artilcle for workaround: Refresh Page Issue in ASP.Net[^]
