Unity中，获取指定名称的文件的路径

    // 相对路径指的是Assets下
    public static string GetAssetPath(string assetName, bool isAbsolutePath = false)
    {
        var guids = AssetDatabase.FindAssets(assetName);
        if (guids.Length > 0)
        {
            var relativePath = AssetDatabase.GUIDToAssetPath(guids[0]);
            var path = isAbsolutePath ? Path.Join(Directory.GetCurrentDirectory(), relativePath) : relativePath;
            return path;
        }
        else
        {
            Debug.Log("Assets下没有该文件：" + assetName);
            return string.Empty;
        }
    }
