Namespace: System.Runtime.Remoting.Messaging
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic (Declaration)

<ComVisibleAttribute(True)> _
<AttributeUsageAttribute(AttributeTargets.Method)> _
Public Class OneWayAttribute _
    Inherits Attribute

Visual Basic (Usage)

Dim instance As OneWayAttribute

[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets.Method)]
public class OneWayAttribute : Attribute

Visual C++

[AttributeUsageAttribute(AttributeTargets::Method)]
public ref class OneWayAttribute : public Attribute

JScript

public class OneWayAttribute extends Attribute

Remarks

When one-way methods are invoked, no reply message or status or information is expected. The OneWayAttribute is used to indicate that the method has a void return and only in parameters. The method cannot throw any exceptions, and ref parameters and return values are not supported. The method can execute synchronously or asynchronously with respect to the caller. The caller cannot make assumptions that the one-way call has executed on the server object when thread control returns.
