C# WPF OpenFileDialog 在 XP 中导致崩溃，但在 Vista 中则不然

我有一个 WPF 应用程序，可以在我的 Vista 开发计算机上正常运行，但不能在生产 XP 机器上运行。唯一的问题是调用 OpenFileDialog.Show()。一旦我调用该方法，应用程序就会在 XP 盒子上终止。

该问题不会触发异常。（我已将该块包围在 try-catch 块中，但无济于事。）当我单击“文件”->“打开”应用程序并在 XP 中退出时。有趣的是，我可以使用“文件”->“保存”并使用“另存为”对话框将文件写入磁盘。我尝试将其构建为 .Net 3.0 和 3.5，但没有什么区别。

我尝试过 Microsoft.Win32.OpenFileDialog 和 System.Windows.Forms.OpenFileDialog 并得到完全相同的症状。

Microsoft.Win32 变体的代码块：

try  
{  
    OpenFileDialog ofd = new OpenFileDialog();
    if (ofd.ShowDialog().Value)
    {
        //do something
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString(), "Error!");
}

我拥有的唯一线索是安全事件日志中的以下（部分）条目。

Event Type:     Failure Audit
Event Source:   Security
Event Category: Object Access
Event ID:       560
Description:
Object Open:
        Object Server:  Security
        Object Type:    Key
        Object Name:    \REGISTRY\MACHINE\SOFTWARE\Microsoft\EnterpriseCertificates\Disallowed
        Accesses:       DELETE
                        READ_CONTROL
                        WRITE_DAC
                        WRITE_OWNER
                        Query key value
                        Set key value
                        Create sub-key
                        Enumerate sub-keys
                        Notify about changes to keys
                        Create link

有什么想法吗？（拜托！）

原文

I have a WPF application that runs fine on my Vista development machine, but not on the production XP boxes. The only problem is with a call to OpenFileDialog.Show(). As soon as I call the method, the application is terminated on the XP box.

The problem does not trigger an exception. (I've surrounded the block in a try-catch block to no avail.) When I click on File->Open the application just up and quits in XP. Interestingly, I can write files to disk with File->Save and using the Save As dialog. I've tried building it to .Net 3.0 and 3.5 but it doesn't make a difference.

I've tried both Microsoft.Win32.OpenFileDialog and System.Windows.Forms.OpenFileDialog and get the exact same symptom.

The code block for the Microsoft.Win32 variant:

try  
{  
    OpenFileDialog ofd = new OpenFileDialog();
    if (ofd.ShowDialog().Value)
    {
        //do something
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.ToString(), "Error!");
}

The only clues I have is the following (partial) entry from the security event log.

Event Type:     Failure Audit
Event Source:   Security
Event Category: Object Access
Event ID:       560
Description:
Object Open:
        Object Server:  Security
        Object Type:    Key
        Object Name:    \REGISTRY\MACHINE\SOFTWARE\Microsoft\EnterpriseCertificates\Disallowed
        Accesses:       DELETE
                        READ_CONTROL
                        WRITE_DAC
                        WRITE_OWNER
                        Query key value
                        Set key value
                        Create sub-key
                        Enumerate sub-keys
                        Notify about changes to keys
                        Create link

Any ideas? (Pleeeease!)
