示例1: Module1

' 导入命名空间
Imports System.IO
Imports System.Diagnostics

Module Module1
    Sub Main()
        Using process As New Process()
            process.StartInfo.FileName = "ipconfig.exe"
            process.StartInfo.UseShellExecute = False
            process.StartInfo.RedirectStandardOutput = True
            process.Start()

            ' Synchronously read the standard output of the spawned process. 
            Dim reader As StreamReader = process.StandardOutput
            Dim output As String = reader.ReadToEnd()
            Console.WriteLine(output)

            process.WaitForExit()
        End Using

        Console.WriteLine(Environment.NewLine + Environment.NewLine + "Press any key to exit.")

示例2: Main

' 导入命名空间
Imports System.IO

Public Module Example
   Public Sub Main()
      For ctr As Integer = 0 To 499
         Console.WriteLine($"Line {ctr + 1} of 500 written: {ctr + 1/500.0:P2}")
      Next

      Console.Error.WriteLine($"{vbCrLf}Successfully wrote 500 lines.{vbCrLf}")
   End Sub
End Module

      p.StartInfo.RedirectStandardOutput = True  
      p.StartInfo.FileName = "Write500Lines.exe"  
      p.Start() 

      ' To avoid deadlocks, always read the output stream first and then wait.  
      Dim output As String = p.StandardOutput.ReadToEnd()  
      p.WaitForExit()

      Console.WriteLine($"The last 50 characters in the output stream are:\n'{output.Substring(output.Length - 50)}'")
   End Sub
End Module
