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();
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();
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
5 m_threadOutput = new Thread( new ThreadStart( DisplayOutput ) );
6 m_threadOutput.Start();
7 WaitHandle.WaitAll( events );
2 AutoResetEvent[] events = new AutoResetEvent[1];
3 events[0] = m_eventOutput;
4
5 m_threadOutput = new Thread( new ThreadStart( DisplayOutput ) );
6 m_threadOutput.Start();
7 WaitHandle.WaitAll( events );
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 }
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 }
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();
4
2 m_txtOutput.SelectionStart = m_txtOutput.Text.Length;
3 m_txtOutput.ScrollToCaret();
