How to use default parameters in C#?

Question

In other languages I can set up the method signature like ``` cookEgg(boolean hardBoiled = true) ``` This defaults the parameter `hardboiled` to `true`, if I don't receive a parameter in the method call. How would I achieve this in C#?

Accepted Answer

At present, you have to overload the method:

```
void cookEgg(bool hardBoiled) { ... }
void cookEgg() { cookEgg(true); }
```

C# 4.0 will add optional arguments - you will be able to write code exactly as in your original sample, and it will work as you'd expect.
