也许我的解决方案会对你有所帮助。
我的 C#“应用程序”是用作 WIX 的 CustomAction 的类库/dll。我想要一个 TaskDialog 而不是 MessageBox,但我遇到了和你一样的异常,据我所知,清单文件不适用于 C# 类库。我不得不使用多种方法来让我的代码加载正确版本的 comctl32.dll。
我刚刚开始工作,所以我的代码有点凌乱和肥胖。

1) 包括上面第二个链接中的 EnableThemingInScope 类。
2)包括这个修改后的TaskDialog枚举/类:
[Flags]
public enum TaskDialogButtons {
OK = 0x0001,
Cancel = 0x0008,
Yes = 0x0002,
No = 0x0004,
Retry = 0x0010,
Close = 0x0020
}
public enum TaskDialogIcon {
Information = UInt16.MaxValue - 2,
Warning = UInt16.MaxValue,
Stop = UInt16.MaxValue - 1,
Question = 0,
SecurityWarning = UInt16.MaxValue - 5,
SecurityError = UInt16.MaxValue - 6,
SecuritySuccess = UInt16.MaxValue - 7,
SecurityShield = UInt16.MaxValue - 3,
SecurityShieldBlue = UInt16.MaxValue - 4,
SecurityShieldGray = UInt16.MaxValue - 8
}
public enum TaskDialogResult {
None,
OK,
Cancel,
Yes,
No,
Retry,
Close
}
public class StatusDialog {
#region API

#region Core Implementation
private static TaskDialogResult ShowInternal( IntPtr owner, string text, string instruction, string caption, TaskDialogButtons buttons, TaskDialogIcon icon ) {
int p;
using ( new EnableThemingInScope( true ) ) {
int resss = TaskDialog( owner, IntPtr.Zero, caption, instruction, text, (int) buttons, new IntPtr( (int) icon ), out p );
if ( resss != 0 )
throw new InvalidOperationException( "Something weird has happened." + resss.ToString() );
}
switch ( p ) {
case 1:
return TaskDialogResult.OK;
case 2:
return TaskDialogResult.Cancel;
case 4:
return TaskDialogResult.Retry;
case 6:
return TaskDialogResult.Yes;
case 7:

3. 调用它,简单地说:
try {
StatusDialog.Show( "About to test this...", "Heading I won't use.", "Dialog Title", TaskDialogButtons.OK );
} catch ( Exception e ) {
MessageBox.Show( e.ToString(), "Error Found", MessageBoxButtons.OK );
}
4. 结果:
