阅读从Windows Phone 7的文件 [英] Read a file from Windows Phone 7

问题描述

我有一个名为数据/ 在我的项目包含 TXT文件。

I have a folder called data/ in my project that contains txt files.

我配置生成操作到资源来的所有文件。

I configured Build Action to resources to all files.

我尝试这些不同的方式：

I tried these different ways:

var resource = Application.GetResourceStream(new Uri(fName, UriKind.Relative));
StreamReader streamReader = new StreamReader(resource.Stream);
Debug.WriteLine(streamReader.ReadToEnd());

方法2

method 2

IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
string[] fileNames = myIsolatedStorage.GetFileNames("*.txt");

方法3

method 3

using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
{
   using (StreamReader fileReader = new StreamReader(new IsolatedStorageFileStream(fName, FileMode.Open, isf)))
   {
      while (!fileReader.EndOfStream)
      {
        string line = fileReader.ReadLine();
        al.Add(line);
        Debug.WriteLine(line);
      }
   }
}

现在，我尝试不同的方法阅读没有成功，为什么文件？结果
问题出在哪里？

Now, i tried different ways to read files without success, why?
Where is the problem?

有什么不对这些方法？

FNAME 是文件的名称。结果
这是必要的完整路径数据/ FILENAME.TXT？这是无所谓......

fName is the name of the file.
It's necessary the full path data/filename.txt? It's indifferent...

请帮助我这个愚蠢的问题，结果
的感谢。

please help me with this stupid issue,
thanks.

推荐答案

您第二次和放大器;第三个方法是错误的。当您在您的应用程序包括本地的文本文件，你无法通过IS参考它。相反，使用此功能，一旦发现另外返回空将返回文件内容。它为我，希望它为你工作。

Your 2nd & 3rd approaches are wrong. When you include a text file locally in your app, you can't refer it via the IS. Instead, use this function, it will return the file content if found else it will return "null". It works for me, hope it works for you.

请注意，如果文件被设置为内容，文件路径= 数据/文件名。 TXT，但如果它被设置为资源应提到这样的文件路径= /项目名;组件/数据/ FILENAME.TXT。这可能是为什么你第一次的做法可能会失败。

Note, if the file is set as content, the filePath = "data/filename.txt" but if it is set as resource it should be referred like this filePath = "/ProjectName;component/data/filename.txt". That may be why your 1st approach might have failed.

    private string ReadFile(string filePath)
    {
        //this verse is loaded for the first time so fill it from the text file
        var ResrouceStream = Application.GetResourceStream(new Uri(filePath, UriKind.Relative));
        if (ResrouceStream != null)
        {
            Stream myFileStream = ResrouceStream.Stream;
            if (myFileStream.CanRead)
            {
                StreamReader myStreamReader = new StreamReader(myFileStream);

                //read the content here
                return myStreamReader.ReadToEnd();
            }
        }
        return "NULL";
    }
