Implementing pattern matching in C#

Question

In Scala, you can use pattern matching to produce a result depending on the type of the input. For instance:

val title = content match {
    case blogPost: BlogP         


        

Answer 1

Check out my pattern matching implementation: repo

It's based on expressions, so it offers equal perfomance with nested ifs.

Example usage:

string s1 = "Hello";
string s2 = null;

Func> match = new Matcher>
{
     {s => s is None, s => Console.WriteLine("None")},
     {s => s is Some, s => Console.WriteLine((string)s) // or s.Value
};

match(s1); // Hello
match(s2); // None
