how to invoke a static method using c# lambda expressions

To invoke a static method, you can use a static method reference with a lambda expression. Static method reference separates the class name and method name with a double colon (::), as shown below:

ClassName::StaticMethodName

Here is an example demonstrating how to call a static method in a lambda expression.

using System;

public class Program
{
    public static void Main()
    {
        Func<int, int, int> add = Calculator.Add;
        int result = add(5, 3);
        Console.WriteLine(result);
    }
}

public static class Calculator
{
    public static int Add(int a, int b)
    {
        return a + b;
    }
}

In the example above, we used a static method reference Calculator.Add in a lambda expression to call a static method. We then assigned this lambda expression to a Func delegate, passing in 5 and 3 as parameters to execute the static method. Finally, we printed the result to the console.

The output result is 8.
