C#WPF OpenFileDialog导致XP中崩溃，而不是Vista中 [英] C# WPF OpenFileDialog causing crash in XP, not in Vista

问题描述

我有一个WPF应用程序，该程序可以在我的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，该应用程序就会在XP盒中终止.

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.

该问题不会触发异常. (我已经将该块包含在try-catch块中，但无济于事.)当我单击File-> Open应用程序时，刚好在XP中退出.有趣的是，我可以使用File-> Save并使用Save As对话框将文件写入磁盘.我曾尝试将其构建为.Net 3.0和3.5，但没有任何区别.

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.

我已经尝试了Microsoft.Win32.OpenFileDialog和System.Windows.Forms.OpenFileDialog并得到完全相同的症状.

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

Microsoft.Win32变体的代码块:

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!");
}

我仅有的线索是安全事件日志中的以下(部分)条目.

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

有什么想法吗? (快点！)

Any ideas? (Pleeeease!)

推荐答案

感谢您的建议.我验证了注册表权限和完全信任问题.事实证明，尽管我专门针对.Net 3.0构建了应用程序(基于标准的组织形象)，但仍然对.Net 3.5 SP1有依赖性，但我仍然不完全了解.解决我的问题的方法是在所有受影响的计算机上安装.Net 3.5 SP1.

Thanks for the advice. I verified both the registry permissions and the full-trust issue. It turns out that, although I specifically built my application to .Net 3.0 (based on the standard organizational image), there was a dependency on .Net 3.5 SP1 that I still don't fully understand. The solution to my problem was to install .Net 3.5 SP1 on all the affected computers.

我只是想结束循环.再次感谢所有提出想法的人.

I just wanted to close the loop. Thanks, again, to all who contributed ideas.
