OneWayAttribute Class

Marks a method as one way, without a return value and out or ref parameters.

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

[AttributeUsageAttribute(AttributeTargets.Method)] 
[ComVisibleAttribute(true)] 
public class OneWayAttribute : Attribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Method) */ 
/** @attribute ComVisibleAttribute(true) */ 
public class OneWayAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Method) 
ComVisibleAttribute(true) 
public class OneWayAttribute extends Attribute
Not applicable.

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.
