在WPF SaveFileDialog错误

问题描述

我用 Microsoft.Win32.SaveFileDialog 类来保存我的文件。当我保存的文件，并最大限度地减少我的应用程序，我无法恢复回来。它仅用于后会发生 Microsoft.Win32.SaveFileDialog 。这里是code：

I'm using Microsoft.Win32.SaveFileDialog class to save my files. When I saved file, and minimize my app, I can't restore it back. It happens only after when used Microsoft.Win32.SaveFileDialog. Here is code:

Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = String.Format("{0} {1} {2}", ev["b"], ev["a"], ev["c"]);
dlg.DefaultExt = ".csv";
dlg.Filter = "Supported format (.csv)|*.csv";
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
    string s = dlg.FileName;
    //other code
}

文件成功保存，但我不知道如何解决问题，最大限度地减少。有谁知道可能是什么？

File saves successfully, but I don't know how to solve problem with minimizing. Does anybody knows what it could be?

推荐答案

WPF有各种奇怪的方式问题，当您显示的对话框没有父窗口。我还没有与SaveFileDialog看到了这一点直接，但我已经看到了与其它对话框类似的行为。尝试使用.ShowDialog（），您传递父窗口的过载。

WPF has all kinds of weird modality issues when you show dialogs without parent windows. I haven't seen this directly with the SaveFileDialog, but I have seen similar behavior with other dialogs. Try using the overload of .ShowDialog() where you pass in the parent window.
