Can a method return two values C#?
No, you can’t return multiple values from a function in C# (for versions lower than C# 7), at least not in the way you can do it in Python. However, there are a couple alternatives: You can return an array of type object with the multiple values you want in it. You can use out parameters.
How can I return two data types in C#?

- Reference parameters.
- Output parameters.
- Returning an Array.
- Returning an object of class/struct type.

Is it possible to return two variables in a function?
Technically, no you are not able to return two variables in the way you would normally return a variable. You can, however, use references. That way, you can pass multiple variables to a function, and the function will assign them, rather than returning anything: You can’t do it directly (because a return value is singular).
What’s the best way to return values from a function?
Use a struct or a class for the return value. Using std::pair may work for now, but it’s not very clear from the function’s declaration in the header what is being returned and in what order. Returning a structure with self-documenting member variable names will likely be less bug-prone for anyone using your function.
Which is the return type of a C # function?
We all understand that functions in C# have a function signature, function body and a return type. The signature comprises the parameters sent to the function, the function body is the lines of code executed when the function is called and the return type is the type of value returned to the calling function.
