AnonymousPipeClientStream 类

定义

公开匿名管道流的客户端,该管道流既支持同步读写操作,也支持异步读写操作。Exposes the client side of an anonymous pipe stream, which supports both synchronous and asynchronous read and write operations.

public sealed class AnonymousPipeClientStream : System.IO.Pipes.PipeStream
type AnonymousPipeClientStream = class
    inherit PipeStream
Public NotInheritable Class AnonymousPipeClientStream

继承
AnonymousPipeClientStream

示例

下面的示例使用匿名管道将字符串从父进程发送到子进程。The following example sends a string from a parent process to a child process by using anonymous pipes. 此示例在父进程中创建 AnonymousPipeServerStream 对象,它的 PipeDirection 值为 OutThis example creates an AnonymousPipeServerStream object in a parent process with a PipeDirection value of Out. 它还在 PipeDirection 值为 In的子进程中创建 AnonymousPipeClientStream 对象。It also creates an AnonymousPipeClientStream object in a child process with a PipeDirection value of In. 接下来,父进程将用户提供的字符串发送给子进程。The parent process then sends a user-supplied string to the child process. 此字符串将显示在控制台中。The string is displayed to the console.

此示例适用于客户端进程,该进程由服务器进程启动。This example is for the client process, which is started by the server process. 将客户端代码中生成的可执行文件命名 pipeClient.exe,并将其复制到运行此示例时服务器可执行文件所在的目录。Name the resulting executable from the client code pipeClient.exe and copy it to the same directory as the server executable when you run this example. 有关完整的代码示例(包括管道客户端和服务器的代码),请参阅如何:使用匿名管道进行本地进程间通信For the entire code example, including the code for both the pipe client and server, see How to: Use Anonymous Pipes for Local Interprocess Communication.

注解

匿名管道有助于在子进程和父进程之间提供安全的进程间通信。Anonymous pipes help provide safe and secure interprocess communication between child and parent processes. 使用 AnonymousPipeClientStream 类,子进程可以通过父进程连接到和交换信息。The AnonymousPipeClientStream class enables a child process to connect to and exchange information with a parent process.

匿名管道是指通常在父进程和子进程之间传输数据的单向管道。Anonymous pipes are unnamed, one-way pipes that typically transfer data between parent and child processes. 匿名管道始终是本地的;它们不能通过网络使用。Anonymous pipes are always local; they cannot be used over a network. 不支持 InOut PipeDirection 值,因为匿名管道定义为单向。A PipeDirection value of InOut is not supported because anonymous pipes are defined to be one-way.

匿名管道不支持 PipeTransmissionMode.Message 读取模式。Anonymous pipes do not support the PipeTransmissionMode.Message read mode.

必须通过调用 GetClientHandleAsString 方法,从服务器端提供的管道句柄创建匿名管道的客户端。The client side of an anonymous pipe must be created from a pipe handle provided by the server side by calling the GetClientHandleAsString method. 然后,在创建客户端进程时将该字符串作为参数传递。The string is then passed as a parameter when creating the client process. 在客户端进程中,它作为 pipeHandleAsString 参数传递给 AnonymousPipeClientStream 构造函数。From the client process, it is passed to the AnonymousPipeClientStream constructor as the pipeHandleAsString parameter.
