doubt using CodeExpression(codeDOM) in C#

[xievvv]

I am doing my project work using codeDOM in C#.

Can any one tell me how to combine two CodeExpression objects as a single argument.

VWException objException =
new VWException(0, "message" + e.Message);

I want to generate the above line, but its not possible to combine CodePrimitiveExpression and CodePropertyReferenceExpression as a single expression (see the second argument of the code).

Can any one tell the answer means its very use for me?
Thank you in advance!

In order to combine two expressions you need to use a binary operator. The CodeBinaryOperatorExpression allows this. Given expr1 and expr2 you can use the following to generate an addition:

new CodeBinaryOperatorExpression(expr1, CodeBinaryOperatorType.Add, expr2);

HTH.
