Hi Gael.

Could you help me with another one problem?

I have two independent advices, one of them uses BeforeMethodBody and AfterMethodBodyAlways JoinPointKinds, hence creates a finally block. Another one advice uses AfterMethodBodyException JoinPointKinds, hence creates a catch block.

Result of their work are nested instructions blocks, e.g.

Code: Select all

try
    {
        // result of work of the first advice
        IDisposable CS$9861e9;
        try
        {
            CS$9861e9 = this._logbook.GetTrace(this);
            throw new NotImplementedException(); // except this line
        }
        finally
        {
            if (CS$9861e9 != null)
            {
                CS$9861e9.Dispose();
            }
        }
    }
    // this catch block (and the first "try") is the result of work of the second advice
    catch (Exception CS$678028)
    {
        if (!MainForm_ExceptionsHandler.Handle(this, CS$678028))
        {
            throw;
        }
    }


Is it possible to make code like this (finally and catch block are siblings) as the result of work of two advices?

Code: Select all

try
{
   // result of work of the first advice
    IDisposable CS$9861e9;
   
    CS$9861e9 = this._logbook.GetTrace(this);
    throw new NotImplementedException(); // except this line
}
// this catch blockis the result of work of the second advice
catch (Exception CS$678028)
{
     if (!MainForm_ExceptionsHandler.Handle(this, CS$678028))
     {
         throw;
     }
}
finally
{
     if (CS$9861e9 != null)
    {
         CS$9861e9.Dispose();
    }
}


thanks in advance

It is just a matter of aspect priority. Play with IAdvice.Priority: the advice with the lesser value will be the most external block.

I see, but in this case I want two advices to generate code at the same level.

The first advice must generate catch block, the second one must generate finally block, and these blocks must be on the same level.

Is it possible or no?

No, it is not possible.
You have to make two advices and give them different priorities.
