StreamReader的和便携类库 [英] StreamReader and Portable Class Library

问题描述

我写使用便携式类库一个CONFIGMANAGER类。 PCL支持的StreamReader 和的StreamWriter 我想使用的类，但PCL版本这些类不支持传递在施工期间的字符串。 PCL也并不支持 reader.Close（）和 writer.Close（）。最后它不支持的FileStream 类。

所以我在寻找一个答案的任何一个以下几个问题：

1. 我怎样才能获得的StreamReader 和的StreamWriter 在PCL工作
   类？


2. 如何创建一个新的流使用PCL？


3. 还有什么其他alternitives我要加载和保存在PCL文件？

解决方案

使用的Dispose（）而不是关闭（）（或只是包装一切using语句）。我们已经隐藏/删除关闭（）在Windows Store应用程序和新的PCLS，因为它做同样的事情，人们会感到困惑调用哪一个。

考虑使用 PCL存储的跨平台文件系统的访问。

I am writing a ConfigManager class using Portable Class Libraries. PCL supports StreamReader and StreamWriter classes that I want to use, but the PCL version of those classes do not support passing in a string during construction. PCL also does not support the reader.Close() and writer.Close(). Lastly it doesn't support the FileStream class.

So I am looking for an answer to any one of the following questions:

1. How can I get the StreamReader and StreamWriter classes working in a PCL?
2. How can I create a new stream using PCL?
3. What other alternitives do I have to load and save files in a PCL?

解决方案

Use Dispose() instead of Close() (or just wrap everything in a using statement). We've hidden/removed Close() in Windows Store apps and newer PCLs, because it does the same thing and people would be confused about which one to call.

Consider using PCL Storage for cross platform file system access.

Here are some blog posts you may want to refer to for how to approach platform-specific functionality in PCLs:
