Disable Minimize Button, but Keep Cross and Maximize Buttons - WPF, C#
提问by Bubbled86
I'd like to know how to disable the Minimize button, but keep the Maximize/Restore button and the Close button (the red "X").
我想知道如何禁用最小化按钮，但保留最大化/恢复按钮和关闭按钮（红色“X”）。
Here's an image of what I want my window's buttons on the top-right to look like:

You may need to use PInvoke here. Basically you're importing SetWindowLong and GetWindowLong functions and setting corresponding flags to Win API window using it's handle(hwnd)
您可能需要在此处使用 PInvoke。基本上，您正在导入 SetWindowLong 和 GetWindowLong 函数并使用它的句柄（hwnd）为 Win API 窗口设置相应的标志
private const int GWL_STYLE = -16;
private const int WS_MINIMIZE = -131073;
[DllImport("user32.dll", SetLastError = true)]
private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
private static void CanMinimize(Window w)
{
var hwnd = new WindowInteropHelper(w).Handle;
long value = GetWindowLong(hwnd, GWL_STYLE);
SetWindowLong(hwnd, GWL_STYLE, (int)(value & ~WS_MINIMIZE));
}

Blablablaster is basically right -- you need to P/Invoke a couple of Windows API calls -- but the following TechNet article also describes when/where you should make the call to the Windows API:
Blablablaster 基本上是正确的——你需要 P/Invoke 几个 Windows API 调用——但下面的 TechNet 文章还描述了你应该何时/何地调用 Windows API：

Here is how I do it
这是我如何做到的
Private Sub WindowAddChange_StateChanged(sender As Object, e As EventArgs) Handles Me.StateChanged
If sender.windowstate = WindowState.Minimized Then
Me.WindowState = WindowState.Normal
End If
End Sub
