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：
代码语言：javascript复制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();
}
}
