示例1: Process

Using myProcess As New Process()
    Dim myProcessStartInfo As New ProcessStartInfo("net ", "use " + args(0))

    myProcessStartInfo.UseShellExecute = False
    myProcessStartInfo.RedirectStandardError = True
    myProcess.StartInfo = myProcessStartInfo
    myProcess.Start()

    Dim myStreamReader As StreamReader = myProcess.StandardError
    ' Read the standard error of net.exe and write it on to console.
    Console.WriteLine(myStreamReader.ReadLine())
End Using

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
开发者ID:VB.NET开发者,项目名称:System.Diagnostics,代码行数:12,代码来源:Process.StandardError

输出:

The last 50 characters in the output stream are:
49,800.20%
Line 500 of 500 written: 49,900.20%


Error stream: Successfully wrote 500 lines.

示例3: Example

' 导入命名空间
Imports System.Diagnostics

Public Module Example
    Public Sub Main()
        Dim p As New Process()
        p.StartInfo.UseShellExecute = False  
        p.StartInfo.RedirectStandardError = 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.StandardError.ReadToEnd()  
        p.WaitForExit()

        Console.WriteLine($"{vbCrLf}Error stream: {output}")
    End Sub
End Module
' The end of the output produced by the example includes the following:
'      Error stream:
'      Successfully wrote 500 lines.

   Public Sub Main()
      Dim p As New Process()  
      p.StartInfo.UseShellExecute = False  
      p.StartInfo.RedirectStandardOutput = True  
      Dim eOut As String = Nothing
      p.StartInfo.RedirectStandardError = True
      AddHandler p.ErrorDataReceived, Sub(sender, e) eOut += e.Data 
      p.StartInfo.FileName = "Write500Lines.exe"  
      p.Start()  

      ' To avoid deadlocks, use an asynchronous read operation on at least one of the streams.  
      p.BeginErrorReadLine()
      Dim output As String = p.StandardOutput.ReadToEnd()  
      p.WaitForExit()

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