C#: Recursive functions with Lambdas
c#, factorial, lambda, recursion
Solution
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<int, int> fac = null;
fac = n => (n <= 1) ? 1 : n * fac(n - 1);
Problem
The below does not compile: ``` Func<int, int> fac = n => (n <= 1) ? 1 : n * fac(n - 1); ``` Local variable 'fac' might not be initialized before accessing How can you make a recursive function with lambdas? [Update] Here are also two links that I found interesting to read: - Eric Lippert's "Why does a recursive lambda cause a definite assignment error?" - Anonymous Recursion in C#
