如何将 C# 控制台应用程序窗口移动到屏幕中央

问题描述

我正在使用 C# 控制台应用程序。如何将应用程序窗口移动到屏幕中央？

其他详细信息

框架版本：.NET Core 3.1
窗口大小：37x20 (Console.SetwindowSize(37,20);)

解决方法

制作了一个小型实用程序类，可让您将控制台窗口居中。

用法示例：

WindowUtility.MoveWindowToCenter();

完整源代码：

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;

static class WindowUtility
{
    [DllImport("user32.dll",SetLastError = true)]
    static extern IntPtr FindWindow(string lpClassName,string lpWindowName);

    [DllImport("user32.dll",SetLastError = true)]
    static extern bool SetWindowPos(IntPtr hWnd,IntPtr hWndInsertAfter,int X,int Y,int cx,int cy,uint uFlags);

    const uint SWP_NOSIZE = 0x0001;
    const uint SWP_NOZORDER = 0x0004;

    private static Size GetScreenSize() => new Size(GetSystemMetrics(0),GetSystemMetrics(1));

    private struct Size
    {
        public int Width { get; set; }
        public int Height { get; set; }

        public Size(int width,int height)
        {
            Width = width;
            Height = height;
        }
    }

    [DllImport("User32.dll",ExactSpelling = true,CharSet = CharSet.Auto)]
    private static extern int GetSystemMetrics(int nIndex);

    [DllImport("user32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool GetWindowRect(HandleRef hWnd,out Rect lpRect);

    [StructLayout(LayoutKind.Sequential)]
    private struct Rect
    {
        public int Left;        // x position of upper-left corner
        public int Top;         // y position of upper-left corner
        public int Right;       // x position of lower-right corner
        public int Bottom;      // y position of lower-right corner
    }

    private static Size GetWindowSize(IntPtr window)
    {
        if (!GetWindowRect(new HandleRef(null,window),out Rect rect))
            throw new Exception("Unable to get window rect!");

        int width = rect.Right - rect.Left;
        int height = rect.Bottom - rect.Top;

        return new Size(width,height);
    }

    public static void MoveWindowToCenter()
    {
        IntPtr window = Process.GetCurrentProcess().MainWindowHandle;

        if (window == IntPtr.Zero)
            throw new Exception("Couldn't find a window to center!");

        Size screenSize = GetScreenSize();
        Size windowSize = GetWindowSize(window);

        int x = (screenSize.Width - windowSize.Width) / 2;
        int y = (screenSize.Height - windowSize.Height) / 2;

        SetWindowPos(window,IntPtr.Zero,x,y,SWP_NOSIZE | SWP_NOZORDER);
    }
}
