[Unity]

（一）问题

项目开发中常会有开多个分支，同时启动多个 Unity 程序的情况，来回切换的时候就容易混淆，有时候还需要用 Show In Explorer 或者其他标志来确认当前使用的是哪个分支。

于是想在标题栏上显示出当前的工作目录：

• 修改前：
  

• 修改后：
  

（二）代码

1. 声明要调用的系统接口

using System;
using System.Runtime.InteropServices;
using System.Text;

public partial class UpdateUnityEditorProcess
{

    public delegate bool EnumThreadWindowsCallback(IntPtr hWnd, IntPtr lParam);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    public static extern bool EnumWindows(EnumThreadWindowsCallback callback, IntPtr extraData);
    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    public static extern int GetWindowThreadProcessId(HandleRef handle, out int processId);

    [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
    public static extern IntPtr GetWindow(HandleRef hWnd, int uCmd);

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern bool IsWindowVisible(HandleRef hWnd);

    [DllImport("user32.dll")]
    private static extern bool GetWindowText(int hWnd, StringBuilder title, int maxBufSize);

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private extern static int GetWindowTextLength(IntPtr hWnd);

    [DllImport("user32.dll", EntryPoint = "SetWindowText", CharSet = CharSet.Auto)]
    public extern static int SetWindowText(int hwnd, string lpString);
}
