嗨大家和加尔斯， 使用Twitch.tv聊天机器人并遇到IOStreams的问题。我有一个文件（ViewerPoints.csv），我存储了一些任意点，这些点用于在频道中花费时间，该频道将用于我将要在以后编程的小游戏。现在，StreamReader / StreamWriter的每个实例都会在下一个实例访问它之前与.Close（）配对，但是我收到以下错误：
System.IO.IOException was unhandled
HResult=-2147024864
Message=The process cannot access the file 'S:\Programming\Projects\C#\StarBot\StarBot\bin\Debug\ViewerPoints.csv' because it is being used by another process.

InnerException:
本质上该文件已在使用中，但我无法弄清楚它的使用位置和使用方式。我尝试重新启动（因为我正在打开和关闭程序很多），我已经尝试删除重新制作文件。从我可以看到，抛出异常时没有其他StreamReaders / Writers打开，但Process Monitor显示了2个ViewerPoints.csv实例。

我会{\ _}}您的Stream对象触及该文件。
或者使用Dispose代替：
using来自MS link
关闭方法： “关闭当前流并释放与当前流关联的所有资源（例如套接字和文件句柄）。而不是调用此方法，确保正确处理流”
