制作了一个小的实用程序类，允许您将控制台窗口居中。
Usage example:
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)
{

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;

}
public static void MoveWindowToCenter()

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, 0, 0, SWP_NOSIZE | SWP_NOZORDER);
}
