本文介绍了如何运行命令行从code命令的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我需要做两件事:运行一个批处理文件(正常工作),并运行一个命令(不工作)。该方法的指令引发异常找不到文件。如果我打开一个CMD窗口,并键入命令,它完美的作品。
I need to do 2 things: run a batch file (works fine), and run a command (does not work).The method for the command throws the exception 'file not found'. If I open a cmd window, and type the command, it works perfectly.
private static void Rescan()
{
//System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo("DEVCON ReScan");
//psi.RedirectStandardOutput = true;
//psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
//psi.UseShellExecute = false;
//System.Diagnostics.Process proc = System.Diagnostics.Process.Start(psi);
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = "DEVCON ReScan";
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.UseShellExecute = false;
proc.Start();
proc.WaitForExit();
System.IO.StreamReader myOutput = proc.StandardOutput;
proc.WaitForExit(4000);
if (proc.HasExited)
{
string output = myOutput.ReadToEnd();
FileIO.WriteLog(_writePath, output);
}
}
本评论code也抛出了同样的异常。
The commented code also throws the same exception.
推荐答案
DEVCON重新扫描
是真正的可执行文件的名称?我猜的可执行文件是DEVCON,而重新扫描参数。这意味着你必须设置StartInfo.FileName为DEVCON和StartInfo.Arguments以重新扫描。
DEVCON ReScan
is really the name of the executable? I guess the executable is DEVCON, while ReScan is a parameter. This means you have to set StartInfo.FileName to "DEVCON" and StartInfo.Arguments to "ReScan".
