在输入方法之前找不到文件或它的依赖项之一 [英] Could not find file or or one of its dependencies thrown before method is entered

问题描述

我想使用 Framework 4.7.2 库中的 windows 窗体

I want to use a windows form that is in a Framework 4.7.2 library

我有以下堆栈;

Framework 4.72 XAF Winforms exe which references
Framework 4.7.2 library1 which references
Framework 4.7.2 library2 which references a a standard2.0 library

我在 Library2 中有以下代码

I have the following code in Library2

   public static void ShowMessageBox()
    {
        MessageBox.Show("hi");
    }

    public static void ShowForm() // errors when this is called
    {
        var form = new Form1(); // debugger can not reach here
        MessageBox.Show("hi2");
    }

我可以调用 ShowMessageBox但是，如果我调用 ShowForm，我会立即收到 System.IO.FileNotFoundException 异常.永远不会到达实例化表单的行.

I can call ShowMessageBox However if I call ShowForm I get a System.IO.FileNotFoundException exception occurs immediately. The line that instantiates the form is never reached.

System.IO.FileNotFoundException: 'Could not load file or assembly 'MyLibrary, 
Version=0.0.0.0, Culture=neutral, PublicKeyToken=a3471ea16b9add4c' 
or one of its dependencies. The system cannot find the file specified.'

推荐答案

当我注意到 library2 中的一些旧引用旁边显示了一些黄色三角形时，我能够克服即时错误.我删除了那些引用.

I was able to get past the immediate error when I noticed that there were some yellow triangles displaying beside some old references in library2. I deleted those references.

现在错误发生在方法中，并显示了丢失文件的名称.

Now the error occurs within the method and the name of the missing file is shown.
