unity编辑器模式下怎么刷新Scene视图？

[liuhaopen]

我有个插件需求:
选中Image节点后，再点击Assets视图的图片后就自动设为其节点新图，这个功能是可以了，但是Scene视图里的节点没更新到新图片，看它的属性页是已经赋值成功的，要随便做一些操作引起编辑器刷新才能看到新的效果，所以我想问下怎么在代码里刷新编辑器模式下的Scene视图。代码如下：

using UnityEngine;
using UnityEditor;
using NUnit.Framework;
using UnityEditor.SceneManagement;

public class SceneEditor {

    static Object LastSelectObj = null;
    static Object CurSelectObj = null;
    [InitializeOnLoadMethod]
    static void Init()
    {
        SceneView.onSceneGUIDelegate += OnSceneGUI;
        Selection.selectionChanged += delegate()
        {
            LastSelectObj = CurSelectObj;
            CurSelectObj = Selection.activeObject;
            UnityEngine.Object[] arr = Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.TopLevel);
            if (arr != null && arr.Length > 0)
            {
                GameObject selectObj = LastSelectObj as GameObject;
                string assetPath = AssetDatabase.GetAssetPath(arr[0]);
                if (selectObj != null)
                {
                    SuyouUI.ImageBox image = selectObj.GetComponent<SuyouUI.ImageBox>();
                    if (image != null)
                    {
                        image.SetImage(assetPath);
                        //想刷新Scene视图但是没用，应该怎么弄？
                        UnityEditor.SceneManagement.EditorSceneManager.MarkAllScenesDirty();
                        SceneView.lastActiveSceneView.Repaint();
                        Selection.activeGameObject = LastSelectObj as GameObject;
                    }
                }
            }
        };
    }
}

SetDirty

可以了，SetImage后再调用下EditorUtility.SetDirty(selectObj);就可以更新为最新图片了，十分感谢！
