为什么ShowDialog在MonoDevelop中崩溃？

[英]Why Does ShowDialog Crash in MonoDevelop?

原文 2011-12-21 16:51:57 3 2 c#/ .net/ mono/ monodevelop

I have a trouble building and running my working C# project under MonoDevelop. 我在MonoDevelop下构建和运行我正在运行的C＃项目时遇到了麻烦。

Any call of OpenFileDilog.ShowDialog() shows me a window with a proper title, but completely blanc. 任何OpenFileDilog.ShowDialog()调用都会向我显示一个具有正确标题的窗口，但完全是空白的。 The executive waits for a while and than crashes. 执行官等待一段时间而不是崩溃。

I also have another C# project build in the same MonoDevelop enviroment, that works fine. 我还在同一个MonoDevelop环境中构建了另一个C＃项目，工作正常。 Well, not that fine, but at least OpenFileDialogs doesn't lead to crash. 好吧，不是那么好，但至少OpenFileDialogs不会导致崩溃。 So I'm a little bit puzzled here. 所以我在这里有点困惑。 Can it be project specific? 它可以是项目特定的吗？ What should I do to avoid it? 我该怎么做才能避免它？

Upddate: It works the same way with any modal form. 更新：它与任何模态形式的工作方式相同。 So It's not OpenFileDilog , it's ShowDialog() . 所以它不是OpenFileDilog ，它是ShowDialog() 。 And it might have something to do with some other windows open by ShowDialog caller. 它可能与ShowDialog调用者打开的其他窗口有关。

So. 所以。 I have a form, which opens some other forms with Show() , and then tries to open another window with ShowDialog() - and goes then as descibed above. 我有一个表单，用Show()打开一些其他表单，然后尝试用ShowDialog()打开另一个窗口 - 然后按照上面的描述进行操作。

Some details: 一些细节：

Mac OS X 10.6.8 (10K594) Mac OS X 10.6.8（10K594）

Mono 2.10.6 单声道2.10.6

MonoDevelop 2.8.5 MonoDevelop 2.8.5

2 个解决方案

我可以确认，将FormBorderStyle设置为System.Windows.Forms.FormBorderStyle.FixedToolWindow在某些情况下会在Mono中生成崩溃（这时我从具有FixedToolWindow的对话框中打开MessageBox ）。

Seems to be a bug in Mono. 似乎是Mono中的一个错误。 My other non modal windows had FormBorderStyle set to FixedToolWindow . 我的其他非模态窗口将FormBorderStyle设置为FixedToolWindow 。 As soon as I set it back to Sizable , everything works normal. 一旦我将它设置回Sizable ，一切正常。
