Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

Public Shared Function ReferenceMatchesDefinition ( _
    reference As AssemblyName, _
    definition As AssemblyName _
) As Boolean
public static bool ReferenceMatchesDefinition(
    AssemblyName reference,
    AssemblyName definition


Return Value

Type: System.Boolean
true if the loader resolves definition to the same assembly as reference; otherwise, false.


Both reference and definition are resolved by the loader, including policy evaluation, and then definition is tested for equality to reference.

The order of comparison is important, because the method tests whether the loader will accept definition to satisfy a load request for reference. Such mappings are not necessarily two-way.

For example, you might compare "MyAssembly, Version=, Culture=neutral, PublicKeyToken=null" with "MyAssembly, Version=, Culture=neutral, PublicKeyToken=null".

If the handler for the AssemblyResolve event has a reference display name, it can pass the display name of an available assembly as the definition parameter, to see if the available assembly would satisfy the load request. If so, the handler can return the available assembly.
