I want to open new View from the XAML.cs,
I try this code:

But I have Error : <the Show doesn't exist ..

What I have tried:

private void canMain_MouseDown(object sender, MouseButtonEventArgs e)
            if (e.ChangedButton == MouseButton.Left && e.ClickCount == 2)
                RoleManagmentview openwindow=new RoleManagmentview ();

What's the base class for RoleManagmentview?

The base class for RoleManagmentview is an UserControl .
and the RoleManagmentview is Window

Sorry, that doesn't make any sense. It can't inherit from both UserControl and Window; they're two completely separate classes.

ok I understand ,
I modify the two Views to Window, so what can I do?

If the RoleManagmentView class inherits from Window, then it will have a Show method:

As discussed in the comments, changing RoleManagmentView from a UserControl to a Window resolved the problem.
