Trying to utilize combination of generic parameters in C#

Trying to utilize combination of generic parameters in C#

In C#, you can use combination of generic parameters to define a class or method that can work with different types. Here's an example:

public class MyClass<T, U> { public void DoSomething(T param1, U param2) { // Your code here } }

In this example, MyClass is a generic class with two type parameters, T and U. The DoSomething method accepts two parameters of types T and U, respectively.

You can instantiate an object of this class with specific types as follows:

var obj = new MyClass<int, string>(); obj.DoSomething(10, "hello");

In this example, obj is an instance of MyClass with T set to int and U set to string. The DoSomething method is called with an integer and a string as parameters.

You can also define methods that accept multiple generic type parameters as follows:

public class MyClass { public void DoSomething<T, U>(T param1, U param2) { // Your code here } }

In this example, MyClass is a non-generic class that contains a generic method with two type parameters, T and U. The DoSomething method accepts two parameters of types T and U, respectively.

You can call this method with specific types as follows:

var obj = new MyClass(); obj.DoSomething<int, string>(10, "hello");

In this example, obj is an instance of MyClass. The DoSomething method is called with T set to int and U set to string, and an integer and a string as parameters.

By utilizing combination of generic parameters, you can create classes and methods that can work with different types in a flexible and efficient manner.
