Has worked like a magic for me.
Can it be made as a modal dialog?

<hr>

Ans : ShowDialog it self make it as Modal Dialog.. ...

}|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|2042410|它的用法可能和UserControlInstance.ShowDialog()一样简单。更好的自定义实现方法是扩展Window类，并使用设计器和代码对其进行自定义，以获得任何功能。|unstyled|2042411|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|J|8|@]|9|@]|A|$]]|$1|G|3|-4|5|F|7|K|8|@]|9|@]|A|$]]]|H|$]]

 public static DialogResult ShowDialog(this UserControl @this, string title)

The use of it maybe as simple as UserControlInstance.ShowDialog().
A better customized implementation would be by extending the Window class and customizing it using the the designer and code to get any functionality.

blocks|key|2042434|text|我知道这是针对.net+3.5的，但这里有一个适用于.net+2.0的可行解决方案|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2042435|++MyUserControl+myUserControl=+new+MyUserControl();

I know this is for .net 3.5, but here is a workable solution for .net 2.0

<pre><code> MyUserControl myUserControl= new MyUserControl();

 Form window = new Form
 {
 Text = "My User Control",
 TopLevel = true,
 FormBorderStyle = FormBorderStyle.Fixed3D, //Disables user resizing
 MaximizeBox = false,
 MinimizeBox = false,
 ClientSize = myUserControl.Size //size the form to fit the content
 };

 window.Controls.Add(myUserControl);
 myUserControl.Anchor = AnchorStyles.Top | AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right;
 window.ShowDialog();
</code></pre>

blocks|key|2042455|text|您也可以使用MaterialDesignThemes.Wpf+(可在NuGet、.NET+4.5%2B上下载)。然后，您可以简单地执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2042456|{

You can also use MaterialDesignThemes.Wpf (downloadable on NuGet, .NET 4.5+). Then you can simply do:

<pre><code>{
 var view = new YourUserControl();
 var result = await DialogHost.Show(view, "RootDialog", ClosingEventHandler);

private void ClosingEventHandler(object sender, DialogClosingEventArgs eventArgs)
{ } //Handle Closing here

blocks|key|1828287|text|如果通过‘sixlettervariable’得到的答案被这样修改，它就能正常工作|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1828288|private+void+button1_Click+(+object+sender,+RoutedEventArgs+e+)++++++++++++++++++

If the answer by 'sixlettervariables' is modified as so, it works

<pre><code>private void button1_Click ( object sender, RoutedEventArgs e ) 
{
 Window window = new Window
 {
 Title = "My User Control Dialog",
 Content = new UserControl ( ),

 window.ShowDialog ( );
