我在c＃中有一个activex控件项目，它引用了我自己构建的dll文件。
现在我点击一个按钮，我看到它失败了，但是这个例外：
System.IO.FileNotFoundException：无法加载文件或程序集 'MtnLib，版本= 1.0.0.0，文化=中立， PublicKeyToken = 111045ceeaeac3e4'或其依赖项之一。该 系统找不到指定的文件。文件名称：'MtnLib， Version = 1.0.0.0，Culture = neutral，PublicKeyToken = 111045ceeaeac3e4'
在CSActiveX.MtnControl.button1_Click（Object sender，EventArgs e）
在System.Windows.Forms.Control.OnClick（EventArgs e）at System.Windows.Forms.Button.OnClick（EventArgs e）at System.Windows.Forms.Button.OnMouseUp（MouseEventArgs mevent）at at System.Windows.Forms.Control.WmMouseUp（Message＆amp; m，MouseButtons 按钮，Int32点击）at System.Windows.Forms.Control.WndProc（Message＆amp; m）at System.Windows.Forms.ButtonBase.WndProc（Message＆amp; m）at System.Windows.Forms.Button.WndProc（Message＆amp; m）at System.Windows.Forms.Control.ControlNativeWindow.OnMessage（Message＆amp; m） 在System.Windows.Forms.Control.ControlNativeWindow.WndProc（Message＆amp; m）在System.Windows.Forms.NativeWindow.Callback（IntPtr hWnd，Int32） msg，IntPtr wparam，IntPtr lparam）
我启用了日志，这些是日志：
日志：DisplayName = MtnLib，版本= 1.0.0.0，文化=中性， PublicKeyToken = 111045ceeaeac3e4（完全指定）LOG：Appbase = file：/// C：/ Program Files（x86）/ Internet Explorer / LOG：Initial PrivatePath = NULL调用程序集：CSActiveX，Version = 1.0.0.0， Culture = neutral，PublicKeyToken = null。 ===日志：此绑定在LoadFrom加载上下文中启动。警告：不会在LoadFrom上下文中探测本机映像。原生图像只会是 在默认加载上下文中进行探测，与Assembly.Load（）一样。日志：没有 找到应用配置文件。日志：使用主机配置 file：LOG：使用来自的机器配置文件 C：\ WINDOWS \ Microsoft.NET \框架\ v4.0.30319 \ CONFIG \ machine.config中。 日志：政策后参考：MtnLib，版本= 1.0.0.0，文化=中立， PublicKeyToken = 111045ceeaeac3e4日志：尝试下载新网址 file：/// C：/ Program Files（x86）/ Internet Explorer / MtnLib.DLL。日志： 试图下载新的URL文件：/// C：/ Program Files（x86）/ Internet 资源管理器/ MtnLib / MtnLib.DLL。日志：尝试下载新网址 file：/// C：/ Program Files（x86）/ Internet Explorer / MtnLib.EXE。日志： 试图下载新的URL文件：/// C：/ Program Files（x86）/ Internet 资源管理器/ MtnLib / MtnLib.EXE。日志：尝试下载新网址 文件：/// C：/temp/MtnControl/Debug/MtnLib.DLL。日志：尝试下载 新URL文件：/// C：/temp/MtnControl/Debug/MtnLib/MtnLib.DLL。日志： 试图下载新的URL 文件：/// C：/temp/MtnControl/Debug/MtnLib.EXE。日志：尝试下载 新的URL文件：/// C：/temp/MtnControl/Debug/MtnLib/MtnLib.EXE。
我的项目引用了MtnLib.dll，我确实看到了C：\ temp \ MtnControl \ Debug \ MtnLib.dll下的文件所以我不明白为什么IE没有找到该文件。
这是我的控制：

我在visual studio中检查了Register for COM Interop，我的控件显示正确，只找不到MtnLib.dll。
顺便说一句，我在Windows 7 64位中使用IE 8。
答案 0 :(得分：0)
当MtnLib是x64库时，我发现我使用32位IE测试控件。
