推荐答案

in您的aspx页面代码文件是 CodeBehind =L_PaperSet.aspx.cs但您可能已将其重命名为其他内容。给出WebForm2类cs文件的正确名称，然后这个错误就会消失。

in your aspx page code file is CodeBehind="L_PaperSet.aspx.cs" but you may have renamed it to something else. give the correct name of WebForm2 class cs file, then this error will be vanished.

你试过公开这个方法吗？

Have you tried to make the method public?

protected void Timer1_Tick(object sender, EventArgs e)
public void Timer1_Tick(object sender, EventArgs e)
{
    NewMethod();
}

我遇到了完全相同的问题，并意识到这是一个......错误的客户问题。



我曾要求他们将一些代码添加到他们的 .aspx 文件中，还添加到他们的 .aspx中。 cs 文件（包含 timer_tick 函数）。



他们这样做了。 ..一切正常并在本地运行......但是，在Visual Studio 2015中，他们决定右键单击该特定的.aspx文件，然后发布那个文件。



那么，发生了什么？



.aspx 文件已成功部署到其IIS服务器，但其.cs文件中的C＃代码已编译为 bin中的 .dll 文件目录，但是他们还没有发布那个。



是的......我知道....


所以，如果你确实发现你的命名空间做完全匹配，但你仍然会收到这个错误... w ell ...检查 bin 目录.... !!

I had exactly the same problem, and realised it was a... errrm.. client problem.

I had asked them to add some code to their .aspx file, and also to their .aspx.cs file (which contained the timer_tick function).

They did this... it all worked fine and ran locally... but then, in Visual Studio 2015, they had decided to right click on just that particular .aspx file, and just publish that file.

So, what happened ?

The .aspx file successfully deployed to their IIS server, but the C# code in their .cs file had been compiled into a .dll file in their bin directory, but they hadn't published that.

Yeah... I know....

So, if you do find that your namespaces do match exactly, but you're still getting this error... well... check your bin directory....!!
