Question

What are the pro cons with having delegates having a reserved definition type.

For example in c if I want to define a function that takes a pointer to a function I can simply define

void F(bool (*pFn)(int));

In c# I have to take the extra step of first defining the delegate type similar if I had to create a typedef in c before I could define the above function

delegate bool del(int s);
void F(del d){...}

I find the c# style to bee less clear and flexible.

A: Am I not realizing that this is doable in C#
B: Would this be a poor language feature to add by introducing the complexity of c type declaration system.

Let me clarify I know the fucn is available i’w wondering if there is a way to define an arbitrary delegate.

Answer 1

Func in .NET 3.5 will let you have up to 4 in parameters and 1 return value. Func in .NET 4 will let you have up to 16 in parameters and 1 return value. If you need more than that you probably should get a quantum computer.

Also Action has the same limits in .NET 3.5 and .NET 4 with the exception of the return value.
