What are out parameters in C#?

Can you explain what out parameters are in C#?

Sure! Out parameters in C# allow a method to return multiple values. They are defined using the 'out' keyword.

How do I use out parameters in a method?

You define the parameter with 'out' in the method signature and then assign a value to it inside the method.

Can you give me an example of using out parameters?

Of course! Here's a simple example:

void GetValues(out int a, out int b) {
    a = 5;
    b = 10;
}

GetValues(out int x, out int y);

This will set x to 5 and y to 10.

Are there any limitations to using out parameters?

Yes, you must assign a value to an out parameter before the method exits, and they cannot be optional.
