我用 SharpShell 编写了这个简单的 shell 扩展(资源管理器上下文菜单):

[ComVisible(true)]
[COMServerAssociation(AssociationType.AllFiles)]
public class SampleExtension : SharpContextMenu
{
    protected override bool CanShowMenu()
    {
        return true;
    }
    protected override ContextMenuStrip CreateMenu()
    {
        var menu = new ContextMenuStrip();
        var item = new ToolStripMenuItem
        {
            Text = "Hello world!"
        };
        menu.Items.Add(item);
        return menu;
    }
}

它可以与 SharpShell 服务器管理器一起调试,但是当我尝试通过srm.exe命令行安装它时,我得到:

srm.exe install ..\SampleExtension\bin\Debug\CountLinesExtension.dll -codebase  

System.ComponentModel.Composition.CompositionContractMismatchException was unhandled

如何解决这个问题?

我们遇到了同样的问题。原来我们只是没有从与我们的 dll 相同的目录运行 srm.exe。我们的 dll 包含其他 dll,因此无法以这种方式加载。一旦我们在同一个目录中运行 srm.exe 和我们的 dll,它就可以工作了。
