Hi All,

Sorry for trouble you. I have some questions on the policy injection.

1、How to match the method that's contain the arguments.

    I can intercept the method either contain the arguments or not with the arrtribute.

    [MyLogHandler("Message")] public virtual void MethodA(); [MyLogHandler("Message")] public virtual void MethodB(string arg);

    But once I intercept the method with the configuraion, It seems no effect with the MethodB(contain the arguments.)


    <add name="Policy">        


     <add type="Microsoft.Practices.EnterpriseLibrary.PolicyInjection.MatchingRules.MethodSignatureMatchingRule, Microsoft.Practices.EnterpriseLibrary.PolicyInjection, Version=5.0.414.0, Culture=neutral,         PublicKeyToken=31bf3856ad364e35"              match="MethodA"  name="Method Signature Matching Rule" />      

  //It's no effect when it's math to the "MethodB". Did I lose some property to config.



   <add Message="Test Success" ParameterName="TestParm" type="InterceptionBlockApplication.MyLogCallHandler, InterceptionBlockApplication, Version=, Culture=neutral, PublicKeyToken=null"              name="MyLogCallHandler" />        




2、How to add the multiple matchingRules

  Now I can add the multiple rules with the follows:



 <add type="*"              match="Method1"  .../>

<add type="*"              match="Method2"  .../>

<add type="*"              match="Method3"  .../>


Can I do it :



 <add type="*"      >


         <add match="Method1" />

        <add match="Method2" />

        <add match="Method3" />




When I try that It will throw the exception that "Do not contain the matches property."

3、Once I have to intercept to many methods whether should I add the rules mapping to all the methods?

 If I have 1000 method to intercept, I had to write 1000 times <add match="you must write 1000 times" /> ??????  T_T


I will be appreciate for any help. Best Regards.

I have found one way to resolve. I can use the membername matchingrules.

1) Entlib has no out of the box matching rule that check if a particular method contains arguments. You have to create a custom matching rule to achieve that.

2) Yes, you can add as many match name as you want for a particular matching rule.

3) You can also use Assembly Matching Rule, where all the methods inside the specified assembly name will be intercepted.
