示例1: ImportPolicy
#Region "IPolicyImporter Members"
Public Const name1 As String = "acme"
Public Const ns1 As String = "http://Microsoft/WCF/Documentation/CustomPolicyAssertions"
'
' * Importing policy assertions usually means modifying the bindingelement stack in some way
' * to support the policy assertion. The procedure is:
' * 1. Find the custom assertion to import.
' * 2. Insert a supporting custom bindingelement or modify the current binding element collection
' * to support the assertion.
' * 3. Remove the assertion from the collection. Once the ImportPolicy method has returned,
' * any remaining assertions for the binding cause the binding to fail import and not be
' * constructed.
'
Public Sub ImportPolicy(ByVal importer As MetadataImporter, ByVal context As PolicyConversionContext) Implements IPolicyImportExtension.ImportPolicy
Console.WriteLine("The custom policy importer has been called.")
' Locate the custom assertion and remove it.
Dim customAssertion As XmlElement = context.GetBindingAssertions().Remove(name1, ns1)
If customAssertion IsNot Nothing Then
Console.WriteLine("Removed our custom assertion from the imported " & "assertions collection and inserting our custom binding element.")
' Here we would add the binding modification that implemented the policy.
' This sample does not do this.
