怎样才能隐式的调用一个命令行的程序，并捕获该进程的标准输出？

Question

Process myProcess = new Process(); 
myProcess.StartInfo.FileName ="c:\\yourexe.exe"; 
myProcess.StartInfo.Arguments = strArguments; 
myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; 
myProcess.Start();
myProcess.Kill();

Answer 1

Process p = new Process();
ProcessStartInfo psI = new ProcessStartInfo("cmd");
psI.UseShellExecute = false;
psI.RedirectStandardOutput = true;
psI.CreateNoWindow = true;
p.StartInfo = psI;
p.Start();
string output = p.StandardOutput.ReadToEnd();

Answer 2

try：System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo = new System.Diagnostics.ProcessStartInfo("cmd");
process.StartInfo.CreateNoWindow = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.UseShellExecute = false;
process.Start();
System.IO.StreamWriter writer = process.StandardInput;
writer.AutoFlush = true;
System.IO.StreamReader reader = process.StandardOutput;writer.WriteLine("ping www.csdn.net");
writer.Close();process.WaitForExit();
MessageBox.Show(reader.ReadToEnd());

reader.Close();

Answer 3

在.net中不支持管道，代替的应该是.net remoting
使用process时，因为命令行不在事件队列中，不能相应用户输入，当命令行要求输入数据是程序总是处于阻塞状态

Answer 6

使用比如ping 127.0.0.1 > a.txt也可以，结果会写到一个文本文件里，直接读就行了
