AnonymousPipeClientStream.ReadMode 属性

定义

命名空间:

System.IO.Pipes

程序集:

System.IO.Pipes.dll

Source:

AnonymousPipeClientStream.cs

设置 AnonymousPipeClientStream 对象的读取模式。

public:
 virtual property System::IO::Pipes::PipeTransmissionMode ReadMode {  void set(System::IO::Pipes::PipeTransmissionMode value); };

public override System.IO.Pipes.PipeTransmissionMode ReadMode { set; }

member this.ReadMode : System.IO.Pipes.PipeTransmissionMode

Public Overrides Property ReadMode As PipeTransmissionMode

属性值

PipeTransmissionMode

PipeTransmissionMode 对象的 AnonymousPipeClientStream。

例外

ArgumentOutOfRangeException

传输模式无效。 对于匿名管道，只支持 Byte

NotSupportedException

转换模式为 Message。

IOException

连接断开或出现其他 I/O 错误。

ObjectDisposedException

管道已关闭。

示例

以下示例使用匿名管道将字符串从父进程发送到子进程。 在此示例中，在 AnonymousPipeClientStream 子进程中创建 对象。
