# C# Lambdas Part 3, Setting Parameters Up Front, and Mismatching Func and Action Definitions

**[No Dogma Blog \(Bryan Hogan\)](https://daily.dev/sources/bryanhogan)** · 4 min read · 0 upvotes · 0 comments

## Summary

Explores two lesser-known lambda techniques in C#: discarding parameters using the underscore pattern `(_, _)` with Func and Action delegates, and satisfying a Func definition with a method whose parameter types don't match by leveraging the lambda as an intermediary. Includes concrete code examples showing how a `Func<string, string>` can wrap a method that takes integers, because the lambda itself handles the type contract.
