[...] long story short: I found this cool thing that lets you use C# 3’s lambdas to describe the work you want to do on the GUI thread. [...]

Hi Bill,

Yes, if you’re using C# 2.0, then you can’t use the “lambda expression” anonymous method syntax. I actually think the correct line would be

+= delegate(object o, DataReceivedEventArgs args) { … }

I think you still need to explicitly declare the types.

I am using c# 2.0. So, instead of

+= (o,args)=>{ block }

use

+= delegate(o,args){ block }

correct?

Hi jhunter,

Hmm, that’s weird. Can you post the line of code where the compiler is complaining?

Also, which version of C# are you targeting? If you’re only using C# 2.0, then the syntax for the lambda expression (”() => …”) isn’t supported. Lambda expressions were a C# 3.0 addition, though you can accomplish the same thing in C# 2.0 using “delegate() { }”, etc.

I tried to do this but in the Invoke method Action is a generic and wants a and then it complains because action wants a parameter (rather than ()) and “o” is not declared. Have I missed a using?
