RemotingServices.Marshal Method (MarshalByRefObject, String, Type)
Assembly: mscorlib (in mscorlib.dll)
'Declaration <SecurityPermissionAttribute(SecurityAction.Demand, Flags := SecurityPermissionFlag.RemotingConfiguration)> _ Public Shared Function Marshal ( _ Obj As MarshalByRefObject, _ ObjURI As String, _ RequestedType As Type _ ) As ObjRef
- Type: System.String
The URI the object specified in the Obj parameter is marshaled with. Can be Nothing.
A ObjRef is a serializable representation of an object used to transfer an object reference across an application domain boundary. Creating a ObjRef for an object is known as marshaling. The ObjRef can be transferred through a channel into another application domain (possibly on another process or computer). Once in the other application domain, the ObjRef must be parsed to create a proxy for the object, generally connected to the real object. This operation is known as unmarshaling.
A ObjRef contains 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 about how to reach the remoting subdivision where the object is located.
The specified Type is used by the remoting infrastructure to limit the scope of the exposed type hierarchy. For example, if object A derives from object B, which derives from object C, and Marshal is called, then the client can cast the proxy between C and B but not to A.
During marshaling, the context from the current thread is used, not the context that was active when the object was created.
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.
