示例

以下示例演示了一种使用匿名管道将字符串从父进程发送到子进程的方法。 在此示例中，在 AnonymousPipeClientStream 子进程中创建对象。

using System;
using System.IO;
using System.IO.Pipes;

class PipeClient
{
    static void Main(string[] args)
    {
        if (args.Length > 0)
        {
            using (PipeStream pipeClient =
                new AnonymousPipeClientStream(args[0]))
            {

                Console.WriteLine("Current TransmissionMode: {0}.",
                   pipeClient.TransmissionMode);

                // Anonymous Pipes do not support Message mode.
                try
                {
                    Console.WriteLine("Setting ReadMode to \"Message\".");
                    pipeClient.ReadMode = PipeTransmissionMode.Message;
                }
                catch (NotSupportedException e)
                {
                    Console.WriteLine("EXCEPTION: {0}", e.Message);
                }

                using (StreamReader sr = new StreamReader(pipeClient))
                {
                    // Display the read text to the console
                    string temp;
                    while ((temp = sr.ReadLine()) != null)
                    {
                        Console.WriteLine(temp);
                    }
                }
            }
        }
        Console.Write("Press Enter to continue...");
        Console.ReadLine();
    }
}

Imports System.IO.Pipes

Class PipeClient

    Shared Sub Main(ByVal args As String())
        If (args.Length > 0) Then

            Using pipeClient As New AnonymousPipeClientStream(args(0))

                Console.WriteLine("Current TransmissionMode: {0}.", _

                ' Anonymous Pipes do not support Message mode.
                Try
                    Console.WriteLine("Setting ReadMode to 'Message'.")
                    pipeClient.ReadMode = PipeTransmissionMode.Message

                    Console.WriteLine("EXCEPTION: {0}", e.Message)
                End Try

注解

对于没有参数的 PipeDirection 构造函数，默认方向为 In。

AnonymousPipeClientStream(PipeDirection, SafePipeHandle)

Source:

AnonymousPipeClientStream.cs

从指定的图柄初始化 AnonymousPipeClientStream 类的新实例。

public:
 AnonymousPipeClientStream(System::IO::Pipes::PipeDirection direction, Microsoft::Win32::SafeHandles::SafePipeHandle ^ safePipeHandle);

public AnonymousPipeClientStream (System.IO.Pipes.PipeDirection direction, Microsoft.Win32.SafeHandles.SafePipeHandle safePipeHandle);

new System.IO.Pipes.AnonymousPipeClientStream : System.IO.Pipes.PipeDirection * Microsoft.Win32.SafeHandles.SafePipeHandle -> System.IO.Pipes.AnonymousPipeClientStream

Public Sub New (direction As PipeDirection, safePipeHandle As SafePipeHandle)

参数

direction

PipeDirection

确定管道方向的枚举值之一。

匿名管道只能是单向的，因此，direction 不能设置为 InOut。

safePipeHandle

SafePipeHandle

此 AnonymousPipeClientStream 对象将封装的管道的安全句柄。

例外

ArgumentException

safePipeHandle 不是有效的句图柄。

ArgumentNullException

safePipeHandle 为 null。

NotSupportedException

将 direction 设置为 InOut。

IOException

发生 I/O 错误，如磁盘错误。

- 或 -

已关闭流。

示例

以下示例演示了一种使用匿名管道将字符串从父进程发送到子进程的方法。 在此示例中，AnonymousPipeClientStream在值为 In的子进程中PipeDirection创建对象。

using System;
using System.IO;

                Console.WriteLine("Current TransmissionMode: {0}.",
                   pipeClient.TransmissionMode);

注解

PipeDirection不支持 值，InOut因为匿名管道定义为单向管道。

AnonymousPipeClientStream(PipeDirection, String)

Source:

AnonymousPipeClientStream.cs

使用指定的管道方向和管道句柄字符串表示形式初始化 AnonymousPipeClientStream 类的一个新实例。

public:
 AnonymousPipeClientStream(System::IO::Pipes::PipeDirection direction, System::String ^ pipeHandleAsString);

public AnonymousPipeClientStream (System.IO.Pipes.PipeDirection direction, string pipeHandleAsString);

new System.IO.Pipes.AnonymousPipeClientStream : System.IO.Pipes.PipeDirection * string -> System.IO.Pipes.AnonymousPipeClientStream

Public Sub New (direction As PipeDirection, pipeHandleAsString As String)

参数

direction

PipeDirection

确定管道方向的枚举值之一。

匿名管道只能是单向的，因此，direction 不能设置为 InOut。

pipeHandleAsString

String

一个表示管道句柄的字符串。

例外

ArgumentException

pipeHandleAsString 是无效的句柄。

ArgumentNullException

pipeHandleAsString 为 null。

NotSupportedException

将 direction 设置为 InOut。

示例

以下示例演示了一种使用匿名管道将字符串从父进程发送到子进程的方法。 在此示例中，AnonymousPipeClientStream在值为 In的子进程中PipeDirection创建对象。
