流读取器中的子字符串错误

本文关键字：字符串 错误 读取 | 更新日期: 2024-10-25 21:22:33

您好，我在为 Unity3D 编写编辑器时遇到问题，我遇到了一个问题，即我正在从具有常规字符串的.txt文件中读取行，然后读取每个常规字符串（表示扩展名的类别）下方的文件扩展名。当我尝试在分配给下一行的字符串上运行子字符串时，问题就出现了。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，打开就可以了。

public bool PopulateList()
{
    bool success = true;
    string path = "Assets/Scripts/Editor/Extensions.txt";
    sourceFile = new FileInfo("Assets/Scripts/Editor/Extensions.txt");
    if (!File.Exists(path))
    {
        Debug.Log("File Does Not Exist");
        TextWriter tw = new StreamWriter(path, true);
        tw.Close();
    }
    string line;
    ExtensionUnit anExtension;
    try
    {
        StreamReader myStreamReader = sourceFile.OpenText();
        line = myStreamReader.ReadLine();
        while (!myStreamReader.EndOfStream)
        {
            anExtension = new ExtensionUnit();
            anExtension.Categories = line;
            line = myStreamReader.ReadLine();
            /*if(line.Substring(0,1) == ".")
            {
                //Debug.Log(line.Substring(0, 1));
            }*/
            //Debug.Log(line.Substring(0, 1));
            /*while(line.Substring(0,1) == ".")
            {
                anExtension.Extensions = line;
                theExtensions.Add(anExtension);
                //Next extension
                line = myStreamReader.ReadLine();
            }*/
            //Empty blank space
            line = myStreamReader.ReadLine();
        }
        myStreamReader.Close();
    }
    catch
    {
        success = false;
    }
    return success;
}

}

流读取器中的子字符串错误

首先读取所有文件数据，然后执行所有逻辑（子字符串等） 

  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);
