unity 編輯器 ---擷取unity編輯器中的所有視窗，并打開顯示，以備後面編輯器擴充

擷取原理：unity 所有視窗界面都繼承自編輯器UnityEditor程式集下的EditorWindow。而所有的編輯器視窗都在UnityEditor程式集裡定義，是以，我們通過反射擷取UnityEditor程式集擷取所有視窗就可以了。

直接上代碼：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Reflection;
using UnityEditor;
using UnityEngine;

class ZzgWindow : EditorWindow
{
    static List<Type> windowList = new List<Type>();
    [MenuItem("TestContextMenu/Open Window")]

    static void Init()
    {
        var window = GetWindow(typeof(ZzgWindow));
        window.titleContent = new GUIContent("ZZG");
        window.position = new Rect(200, 200, 400, 800);
        window.Show();
        windowList = getWindowAll();
    }

    [MenuItem("TestContextMenu/getWindowAll")]

    static void getWindow()
    {
        windowList = getWindowAll();
    }
    /// <summary>
    /// 擷取所有視窗類型
    /// </summary>
    /// <returns></returns>
    static List<Type> getWindowAll()
    {
        Assembly assembly = typeof(EditorWindow).Assembly; //擷取UnityEditor程式集，當然你也可以直接加載UnityEditor程式集來擷取，我這裡圖友善,具體方法看一下程式集的加載Assembly.Load();
        Type[] types = assembly.GetTypes();
        List<Type> list =new List<Type>();
        for (int i = 0; i < types.Length; i++)
        {
            if (isEditorWindow(types[i]))
            {
                if (types[i].Name == "GameView")
                {
                    Debug.Log(types[i].FullName);
                }

                if (types[i].Name == "SceneView")
                {
                    Debug.Log(types[i].FullName);
                }
                list.Add(types[i]);
            }
            
        }
        list.Sort((a,b)=> { return string.Compare(a.Name, b.Name); });  //排序
        return list;
    }
    /// <summary>
    /// 判斷是否是編輯器視窗

    static bool isEditorWindow(Type type)
    {
        int i = 0;
        Type temp = type;
        while (null !=temp&&i<10000)

代碼有注釋，不再解釋了。editorWindow.Close()關閉視窗。editorWindow.Show()顯示視窗

首先關閉所有視窗如下圖：界面真幹淨

然後我們通過點選上面的按鈕打開unity自帶的視窗：
