短视频源码php，自动查找重复贴图

短视频源码php的素材库中，存在各种各样的商品贴图，为了避免出现重复的情况，可以使用如下的代码进行查找：

using System.Collections;
using UnityEngine;
using UnityEditor;
using System.Security.Cryptography;
using System;
using System.IO;
using System.Collections.Generic;
public class FindRepetRes  {
 [MenuItem("Tools/Report/查找重复贴图")]
 static void ReportTexture()
 {
  Dictionary<string,string> md5dic = new Dictionary<string, string> ();
  string[] paths = AssetDatabase.FindAssets("t:prefab",new string[]{"Assets/Resources"});
  foreach (var prefabGuid in paths) {
   string prefabAssetPath = AssetDatabase.GUIDToAssetPath(prefabGuid);
   string[] depend = AssetDatabase.GetDependencies (prefabAssetPath,true);
   for (int i = 0; i < depend.Length; i++) {
    string assetPath = depend [i];
    AssetImporter importer = AssetImporter.GetAtPath(assetPath);
    //满足贴图和模型资源
    if (importer is TextureImporter || importer is ModelImporter) {
     string md5 = GetMD5Hash(Path.Combine(Directory.GetCurrentDirectory(),assetPath));
     string path;
     if (!md5dic.TryGetValue (md5, out path)) {
      md5dic [md5] = assetPath;
     }else {
      if (path != assetPath) {
       Debug.LogFormat ("{0} {1} 资源发生重复！", path, assetPath);
      }
     }
    }
   }
  }
 }
 /// <summary>
 /// 获取文件Md5
 /// </summary>
 /// <returns>The M d5 hash.</returns>
 /// <param name="filePath">File path.</param>
 static string GetMD5Hash(string filePath)
 {
  MD5 md5 = new MD5CryptoServiceProvider();
  return BitConverter.ToString(md5.ComputeHash(File.ReadAllBytes(filePath))).Replace("-", "").ToLower();
 }
}
