Public Function QueryContract (contractIdentifier As String) As IContract

Parameters

contractIdentifier: String

A string that identifies the contract that is being requested.

Returns

IContract

An IContract that represents a contract that a client is requesting from the current contract; null if the current contract does not support the contract that is requested.

Remarks

The QueryContract method enables IContract objects to expose other contracts. QueryContract serves a purpose similar to that of the IUnknown.QueryInterface method in COM.

The format of the strings used to identify contracts is defined by the IContract implementation. It is recommended that you use the AssemblyQualifiedName of the contract that is being queried.
