C#实现Window管道技术
管道技术一般采用Window API来实现,最近试着用C#来实现Windows管道技术,发现C#本身方便的进程线程机制使工作变得简单至极,随手记录一下,推荐给大家。
首先,我们可以通过设置Process类,获取输出接口,代码如下:
1
Process proc = new Process();
2
proc .StartInfo.FileName = strScript;
3
proc .StartInfo.WorkingDirectory = strDirectory;
4
proc .StartInfo.CreateNoWindow = true;
5
proc .StartInfo.UseShellExecute = false;
6
proc .StartInfo.RedirectStandardOutput = true;
7
proc .Start();

![](/Images/OutliningIndicators/None.gif)
3
![](/Images/OutliningIndicators/None.gif)
4
![](/Images/OutliningIndicators/None.gif)
5
![](/Images/OutliningIndicators/None.gif)
6
![](/Images/OutliningIndicators/None.gif)
7
![](/Images/OutliningIndicators/None.gif)
然后设置线程连续读取输出的字符串:
1
eventOutput = new AutoResetEvent(false);
2
AutoResetEvent[] events = new AutoResetEvent[1];
3
events[0] = m_eventOutput;
4![](/Images/OutliningIndicators/None.gif)
5
m_threadOutput = new Thread( new ThreadStart( DisplayOutput ) );
6
m_threadOutput.Start();
7
WaitHandle.WaitAll( events );

4
![](/Images/OutliningIndicators/None.gif)
5
![](/Images/OutliningIndicators/None.gif)
6
![](/Images/OutliningIndicators/None.gif)
7
![](/Images/OutliningIndicators/None.gif)
线程函数如下:
1
private void DisplayOutput()
2
{
3
while ( m_procScript != null && !m_procScript.HasExited )
4
{
5
string strLine = null;
6
while ( ( strLine = m_procScript.StandardOutput.ReadLine() ) != null)
7
{
8
m_txtOutput.AppendText( strLine + "\r\n" );
9
m_txtOutput.SelectionStart = m_txtOutput.Text.Length;
10
m_txtOutput.ScrollToCaret();
11
}
12
Thread.Sleep( 100 );
13
}
14
m_eventOutput.Set();
15
}

![](/Images/OutliningIndicators/InBlock.gif)
10

11
![](/Images/OutliningIndicators/ExpandedSubBlockEnd.gif)
12
![](/Images/OutliningIndicators/InBlock.gif)

![](/Images/OutliningIndicators/ExpandedSubBlockEnd.gif)
14

15

这里要注意的是,使用以下语句使TextBox显示的总是最新添加的,而AppendText而不使用+=,是因为+=会造成整个TextBox的回显使得整个显示区域闪烁
1
m_txtOutput.AppendText( strLine + "\r\n" );
2
m_txtOutput.SelectionStart = m_txtOutput.Text.Length;
3
m_txtOutput.ScrollToCaret();
