如何从VB.NET运行DOS / CMD /命令提示符命令？ [英] How to run DOS/CMD/Command Prompt commands from VB.NET?

问题描述

这个问题是不言而喻的。如果代码是一行长的（这与 Process.Start（...）有关）。我研究了网络，但只发现了旧的例子和那些不工作（至少对我来说）。我想在我的类库中使用这个，运行Git命令（如果这有帮助。）。

The question is self-explanatory. It would be great if the code was one line long (something to do with "Process.Start("...")"?). I researched the web but only found old examples and such ones that do not work (at least for me). I want to use this in my class library, to run Git commands (if that helps?).

推荐答案

方法：

Public Class MyUtilities
    Shared Sub RunCommandCom(command as String, arguments as String, permanent as Boolean) 
        Dim p as Process = new Process() 
        Dim pi as ProcessStartInfo = new ProcessStartInfo() 
        pi.Arguments = " " + if(permanent = true, "/K" , "/C") + " " + command + " " + arguments 
        pi.FileName = "cmd.exe" 
        p.StartInfo = pi 
        p.Start() 
    End Sub
End Class

调用，例如，以这种方式：

call, for example, in this way:

MyUtilities.RunCommandCom("DIR", "/W", true)

EDIT：对于一行上的多个命令，键是& | &&&和||

For the multiple command on one line the key are the & | && and || command connectors

• B - >执行命令A，然后执行命令B.


• B - >执行命令A，并将其所有输出重定向到命令B的
  输入。


• A& B - >执行命令A，在运行
  命令A后评估错误级别，如果退出代码（errorlevel）为0，则只执行
  命令B.


• A || B - >执行命令A，评估此命令的退出代码
  ，如果它不是0，则只执行命令B.

• A & B -> execute command A, then execute command B.
• A | B -> execute command A, and redirect all it's output into the input of command B.
• A && B -> execute command A, evaluate the errorlevel after running Command A, and if the exit code (errorlevel) is 0, only then execute command B.
• A || B -> execute Command A, evalutate the exit code of this command and if it's anything but 0, only then execute command B.
