- What is Func, how and when is it used - Stack Overflow
The Func is a custom delegate defined in System namespace that allows you to point to a method with the same signature (as delegates do), using 0 to 16 input parameters and that must return something
- c# - Func vs. Action vs. Predicate - Stack Overflow
Func is a delegate (pointer) to a method, that takes zero, one or more input parameters, and returns a value (or reference) Predicate is a special kind of Func often used for comparisons (takes a generic parameter and returns bool) Though widely used with Linq, Action and Func are concepts logically independent of Linq
- In C#, What is Func lt;T1, T2 gt;, and what is it for? - Stack Overflow
Func<T, TResult> is just a generic delegate - work out what it means in any particular situation by replacing the type parameters (T and TResult) with the corresponding type arguments (int and string) in the declaration
- c# - Delegates: Predicate vs. Action vs. Func - Stack Overflow
Func : Func can take n input parameters but it will always return the result of the provided type Func<T1,T2,T3,TResult>, here T1,T2,T3 are input parameters and TResult is the output of it Predicate : Predicate is also a form of Func but it will always return bool In simple words it is wrapper of Func<T,bool>
- Why would you use Expression lt;Func lt;T gt; gt; rather than Func lt;T gt;?

Func<out string, ref int, bool> IsIt; illegal 5) You cannot introduce new generic type parameter for Action Func (they are generic already btw, but the type arguments can only be a known type or types specified in the parent method or class), unlike methods
