C#: Recursive functions with Lambdas

Question

The below does not compile:

Func fac = n => (n <= 1) ? 1 : n * fac(n - 1);

Local variable \'fac\' migh

Answer 1

This particular style of function is not supported by C# as a single line declaration. You have to separate out the declaration and definition into 2 lines

Func fac = null;
fac = n => (n <= 1) ? 1 : n * fac(n - 1);
