AnonymousPipeClientStream.ReadMode 属性

定义

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; }
public override System.IO.Pipes.PipeTransmissionMode ReadMode { [System.Security.SecurityCritical] set; }
member this.ReadMode : System.IO.Pipes.PipeTransmissionMode
[<set: System.Security.SecurityCritical>]
member this.ReadMode : System.IO.Pipes.PipeTransmissionMode
Public Overrides Property ReadMode As PipeTransmissionMode

属性值

PipeTransmissionMode 对象的 AnonymousPipeClientStream

属性

例外

传输模式无效。 对于匿名管道,只支持 Byte

转换模式为 Message

连接断开或出现其他 I/O 错误。

管道已关闭。

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,在 AnonymousPipeClientStream 子进程中创建对象。
