以前工作的asp.net webforms应用程序现在抛出这个错误:

系统。MissingMethodException:方法未找到

DoThis方法在同一个类上,它应该可以工作。

我有一个通用的处理程序,这样:

public class MyHandler: IHttpHandler
{
    public void Processrequest(HttpContext context)
    {
      // throws error now System.MissingMethodException: 
      // Method not found.
      this.DoThis(); 
    }

    public void DoThis(){ ... }
}

我也有同样的事情发生,当我有许多MSBuild进程在后台运行时,它们实际上已经崩溃了(它们引用了旧版本的代码)。我关闭VS并在进程资源管理器中杀死所有MSBuild进程,然后重新编译。

其他回答

如果问题是由GAC中的旧版本程序集引起的。 这可以帮助:如何:从全局程序集缓存中删除程序集。

我通过在服务器上安装正确的. net Framework版本解决了这个问题。该网站在4.0版本下运行,它调用的程序集是针对4.5编译的。在安装。net Framework 4.5并将网站升级到4.5之后,一切工作正常。

我在我的ASP中遇到了同样的情况。网的网站。我删除了发布的文件,重启VS,重新清理和重建项目。在下一次发布之后,错误就消失了……

我解决了这个问题,我做了一个搁置我的变化和运行TFS电动工具“烧焦”在我的工作空间(https://visualstudiogallery.msdn.microsoft.com/f017b10c-02b4-4d6d-9845-58a06545627f)。然后我取消了更改并重新编译项目。 这样你就可以清理你工作空间里的“挂着的聚会”,并重新开始一个新的聚会。 当然,这要求您使用TFS。

I had a similar scenario where I was getting this same exception being thrown. I had two projects in my web application solution, named, for sake of example, DAL and DAL.CustSpec. The DAL project had a method named Method1, but DAL.CustSpec did not. My main project had a reference to the DAL project and also a reference to another project named AnotherProj. My main project made a call to Method1. The AnotherProj project had a reference to the DAL.CustSpec project, and not the DAL project. The Build configuration had both the DAL and DAL.CustSpec projects configured to be built. After everything was built, my web application project had the AnotherProj and DAL assemblies in its Bin folder. However, when I ran the website, the Temporary ASP.NET folder for the website had the DAL.CustSpec assembly in its files and not the DAL assembly, for some reason. Of course, when I ran the part that called Method1, I received a "Method not found" error.

为了修复这个错误,我必须从DAL更改AnotherProj项目中的引用。CustSpec到只是DAL,删除了临时ASP中的所有文件。NET Files文件夹,然后重新运行网站。从那以后,一切都开始运转了。我还确保了DAL。在“生成配置”中取消选中CustSpec项目后,没有生成该项目。

我想我要分享这个,也许它能在未来帮助到其他人。
