RemotingServices.Marshal Method (MarshalByRefObject)

.NET Framework 1.1

Takes a MarshalByRefObject, registers it with the remoting infrastructure, and converts it into an instance of the ObjRef class.

[Visual Basic]
Overloads Public Shared Function Marshal( _
   ByVal Obj As MarshalByRefObject _
) As ObjRef
[C#]
public static ObjRef Marshal(
 MarshalByRefObject Obj
);
[C++]
public: static ObjRef* Marshal(
 MarshalByRefObject* Obj
);
[JScript]
public static function Marshal(
   Obj : MarshalByRefObject
) : ObjRef;

Parameters

Obj
The object to convert.

Return Value

An instance of the ObjRef class representing the object specified in the Obj parameter.

Exceptions

Exception Type Condition
RemotingException The Obj parameter is an object proxy.
SecurityException At least one of the callers higher in the callstack does not have permission to configure remoting types and channels.

Remarks

An ObjRef is a serializable representation of an object used to transfer an object reference across an AppDomain boundary. Creating an ObjRef for an object is known as marshaling. The ObjRef can be transferred through a channel into another AppDomain (possibly on another process or computer). Once in the other AppDomain, the ObjRef must be parsed to create a proxy for the object, generally connected to the real object. This operation is known as unmarshaling. ObjRef s contain information that describes the Type and class of the object being marshaled, a URI that uniquely identifies the specific object instance, and communication related information on how to reach the remoting subdivision where the object is located.

During marshaling, the context from the current thread is used, not the context that was active when the object was created. If a URI was not explicitly set by the SetObjectUriForMarshal method, it is automatically generated by the remoting identity infrastructure.

You cannot associate a URI with a proxy for one of two reasons: either the URI was generated at the server side for the object it represents, or the object is well known, in which case the URI is known. For this reason, if the Obj parameter is a proxy, an exception will be thrown. For custom proxies this restriction is relaxed because the transparent proxy is treated as the server object.
