示例
以下示例使用匿名管道将一个字符串从父进程发送到子进程。 在此示例中, AnonymousPipeClientStream 在子进程中创建一个 对象, TransmissionMode 并将 显示到控制台。

#using <System.Core.dll>
using namespace System;
using namespace System::IO;
using namespace System::IO::Pipes;
ref class PipeClient
{
public:
static void Main(array<String^>^ args)
{
if (args->Length > 1)
{
PipeStream^ pipeClient = gcnew AnonymousPipeClientStream(PipeDirection::In, args[1]);
Console::WriteLine("[CLIENT] Current TransmissionMode: {0}.",
pipeClient->TransmissionMode);
StreamReader^ sr = gcnew StreamReader(pipeClient);
// Display the read text to the console
String^ temp;
// Wait for 'sync message' from the server.
do
{
Console::WriteLine("[CLIENT] Wait for sync...");
temp = sr->ReadLine();
}
while (!temp->StartsWith("SYNC"));
// Read the server data and echo to the console.
while ((temp = sr->ReadLine()) != nullptr)
{
Console::WriteLine("[CLIENT] Echo: " + temp);
}
sr->Close();
pipeClient->Close();
}
Console::Write("[CLIENT] Press Enter to continue...");

注解
匿名管道不支持 PipeTransmissionMode.Message 读取模式。 由于此属性的默认值为 PipeTransmissionMode.Byte,因此永远不会有理由在代码中设置此属性。
