c# - 这个错误 : System. Runtime.InteropServices.COMException 是什么？

Question

我一直收到这个错误:

System.Runtime.InteropServices.COMException was thrown on "C:\Users\---\documents\visual studio 2010\Projects\TBrowser\TBrowser\TBrowserWindow.xaml": Error HRESULT E_FAIL has been returned from a call to a COM component.

But I don't have a COM component in my .xaml file. It keeps popping up and saying the position of the error is line 1 column 1 and I just have a Window there and nothing else:

<Window x:Class="TBrowser.TBrowserWindow"

    </DockPanel>

    <Window.TaskbarItemInfo>
        <TaskbarItemInfo x:Name="Display" />
    </Window.TaskbarItemInfo>
</Window>

我什至一直收到这个错误:

System.NullReferenceException was unhandled by user code
  Message=Object reference not set to an instance of an object.

       at MS.Internal.Xaml.Runtime.ClrObjectRuntime.SetValue(Object inst, XamlMember property, Object value)

这就是我正在使用的:

private void TBMenubar1ShowButton_Checked(object sender, RoutedEventArgs e)
{
    TBMenu1.Visibility = System.Windows.Visibility.Visible;
    TBrowser.Properties.Settings.Default.Menubar = System.Windows.Visibility.Visible;
}

我不明白发生了什么。

Answer 1

我认为这是由向需要 32 位 INT 的应用程序发送 64 位 INT 引起的，要解决(如果是这个问题)请按照以下步骤操作。

右键单击项目(在解决方案资源管理器中)-> 属性，构建选项卡，平台目标集 x86。然后进行 Clean-Build 并试一试。
