ProcessStartInfo 和带有参数的事件/异步

Question

我有一个 href 列表，我运行它在这个位置 (svn) 异步查找的命令。在 ProcessOnErrorDataReceived 中，我必须将 s + outLine 添加到列表中。我不知道该怎么做。可以发送 s 到一个事件或者我需要同步调用一个方法。

Search(List<string> path) {
 foreach(var s in path){
   ...
   if (process.StartInfo.RedirectStandardOutput)
                process.OutputDataReceived += ProcessOnErrorDataReceived;
    }
  }

  private void ProcessOnErrorDataReceived(object sendingProcess,
                                  DataReceivedEventArgs outLine)
    {
        Process p = sendingProcess as Process;
        if (outLine.Data != null)
            list.Add(outLine.Data);  //Here +s
    }

Answer 1

尝试这样的事情。这里我们创建一个闭包并捕获 locS 值。因此，当事件发生时，我们可以将捕获的值传递给 ProcessOnErrorDataReceived

Search(List<string> path)
{
  foreach(var s in path)
  {
    ...
    if (process.StartInfo.RedirectStandardOutput)
    {
      var locS = s;
      process.OutputDataReceived += (sender,e) =>
         ProcessOnErrorDataReceived(sender, e, locS);
    }
  }
}

private void ProcessOnErrorDataReceived(object sendingProcess,
  DataReceivedEventArgs outLine, string s)
{
  Process p = sendingProcess as Process;
  if (outLine.Data != null)
      list.Add(outLine.Data + s);  //Here +s
}
