public override System.IO.Pipes.PipeTransmissionMode TransmissionMode { get; }
public override System.IO.Pipes.PipeTransmissionMode TransmissionMode { [System.Security.SecurityCritical] get; }
member this.TransmissionMode : System.IO.Pipes.PipeTransmissionMode
[<get: System.Security.SecurityCritical>]

範例
下列範例示範如何使用匿名管道,將字串從父進程傳送至子進程。 在此範例中, AnonymousPipeServerStream 物件會在父進程中建立,而 TransmissionMode 屬性會顯示至主控台。
