Question

你好我在为Unity3D编写编辑器时遇到了麻烦，我遇到了一个问题，我从一个带有常规字符串的.txt文件中读取行，然后在每个常规字符串下面的文件扩展名（代表扩展的类别））。当我尝试在分配给下一行的字符串上运行子字符串时，会出现问题。当我尝试使用任何子字符串时，文件显示为打开失败，但没有它，打开就好了。

public override void OnRequestPermissionsResult(int requestCode, 
          string[] permissions, [GeneratedEnum] Permission[] grantResults)
{
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_Camera: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.Length > 0 && grantResults[0] == Permission.Granted) {

                // permission was granted, yay! Do the
                // camera-related task you need to do.

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

}

首先读取所有文件数据，然后执行所有逻辑（Substring e.t.c.）

  public bool PopulateList()
    {
        var success = true;
        var path = "Assets/Scripts/Editor/Extensions.txt";

        if (File.Exists(path))
           {
              try
                  {
                     var fileContent = File.ReadAllLines(path);

                     foreach (var line in fileContent)
                        {
                        // Define what lines do you need and get needed extensions 
                        }
                  }

              catch (Exception ex)
                  {
                    Log(ex); // it`s better to know the reason at least
                    success = false;
                  }
           }

       return succes;
     }

尝试在不打开文件的情况下执行此操作：

StreamReader myStreamReader = new StreamReader(sourceFile.FullName);

StreamReader中的子串错误
