C# virtual methods and attributes(properties)

[J2T]

Hi Community,
i'm really new in EA and need u're help please  

The problem is that i don't know exact who i have to mark a method or properties virtual!

For methods i thought it could be 'pure' but when i choose those it always becomes 'abstract' too!And a virtual method isn't a abstract method in c#!

For properties theres only the option 'abstract'!Maby in EA 'abstract' and virtual are the same?!

I hope someone can help me

Look up C# | Modeling Conventions in EA Help. You'll find virtual near the lost of tagged values. I suspect this is what you are looking for.

Thanks for your reply!
But i founded this page too but there only stands that virtual must exist!
But my problem is that i can't find where i can set a property/method virtual. There are only const,static,pure,abstract....

I think you'll have to set up a tagged value, with tag name "virtual" (without quotes) and some kind of value. [Perhaps the value is unimportant, just so long as the tag is defined. Or the value might be an empty string or the Boolean value True.]

What 'thing' actually gets the tag would depend on what you are trying to define. It could be an attribute, operation or even a class.

Of course this does not actually solve your problem; you need an example to see how EA handles this...

I suggest you create a 'toy' piece of C# code with a virtual attribute, operation, or class. Then reverse engineer this into EA. You can then examine the various pieces of the resulting EA model - remember to open and dock the Tagged Value window so you can see what's going on - to see what gets defined where.

You can also export the resulting EA model to XMI and use a text editor to search for "virtual" (with quotes, either single or double).

HTH, David

In the operations dialog there is an advanced button that contains additional options that are language dependent.  This results in the documented tagged values.

Thanks Simon,

I suspected it was around there someplace obvious, but I've not tried it in a while.
