c# - 如何结束进程？

Question

这部分

if (File.Exists(filePath)) {
      string status = new StreamReader(File.OpenRead(filePath)).ReadLine();

      if (status != "SUCCEEDED") {
           File.Delete(filePath);
           createDb();
      } 
}

程序给出异常消息

The process can not access the file '\STATUS.txt' because it is being used by another process.

如何解决这个问题？

修改你的代码如下:

if (File.Exists(filePath)) 
{
    string status;
    using(var streamReader = new StreamReader(filePath))
    {
        status = streamReader.ReadLine();
    }

    if (status != "SUCCEEDED")
    {
        File.Delete(filePath);
        createDb();
    }
}
