In this blog post, we will learn how we can pass a function as a parameter in C# or a method as a parameter in C#.
Pass Function As A Parameter To Another Function In C# Using Func Delegate
We can use the Func delegate as a parameter into a method.
There are several overloads to this method where it takes input and output type parameters.
Let's see how we can use the Func delegate and pass a method as a parameter to another method in C#.
// Main method
// Execution starts here
public static void Main()
{
ThisFunctionTakesAnotherFunction(Function1, 9);
Console.ReadLine();
}
// Function 1 is a normal static function
public static int Function1(int number)
{
return number * 10;
}
// This Function takes a function parameter and some other parameters as well
public static void ThisFunctionTakesAnotherFunction(Func
Result:
90
Let's understand what's happening in the above C# code.
We have created a method called Function1 which takes in an integer parameter and it does some basic multiplication.
We want to pass this method as a parameter to another method.
We have created another method called ThisFunctionTakesAnotherFunction which takes a function as a parameter.
We make use of the Func delegate to pass in the method to another method which then returns a value.
