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($"{vbCrLf}Error stream: {output}")
End Sub
End Module
' The end of the output produced by the example includes the following:
' Error stream:
' Successfully wrote 500 lines.示例4: Example
' 导入命名空间
Imports System.Diagnostics
Public Module Example
Public Sub Main()
Dim p As New Process()
p.StartInfo.UseShellExecute = False
p.StartInfo.RedirectStandardOutput = True
Dim eOut As String = Nothing
p.StartInfo.RedirectStandardError = True
AddHandler p.ErrorDataReceived, Sub(sender, e) eOut += e.Data
p.StartInfo.FileName = "Write500Lines.exe"
p.Start()
' To avoid deadlocks, use an asynchronous read operation on at least one of the streams.
p.BeginErrorReadLine()
Dim output As String = p.StandardOutput.ReadToEnd()
p.WaitForExit()
Console.WriteLine($"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.
