Can you return a tuple in C#?

In C# 7.0, you can actually return multiple values using tuples. A tuple is a kind of dynamic array nominally containing two items that you can interpret as a key and value pair (but it isn’t strictly required). In C#, you can also create tuples containing more than two items.

How do I return a tuple method?

Returning an object of class/struct type. Returning a Tuple….You can call the function using the following code:

  1. int a=10, b=20;
  2. MinMax results = MultipleReturns(a,b);
  3. Console. WriteLine(“Minimum Value: ” + results. min);
  4. Console. WriteLine(“Maximum Value: ” + results. max);

Can a function return a tuple?

Functions can return tuples as return values. In each case, a function (which can only return a single value), can create a single tuple holding multiple elements.

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.

How do you return a method in C#?

Methods can return a value to the caller. If the return type (the type listed before the method name) is not void , the method can return the value by using the return statement. A statement with the return keyword followed by a value that matches the return type will return that value to the method caller.

Is it good to use tuple in C#?

Why should we use Tuples? You may want to use a tuple to represent a set of heterogeneous data and provide an easy way to access that data. You can also take advantage of a tuple to return multiple values from a method or even pass multiple values to a method.

How do you return a variable in C#?

You have to use the return keyword plus the string; it should be return FirstName + ” ” + SecondName + ” ” + DoB+ ” ” + Course+ ” ” + markstring ; with the function declared as public string GetMarkString() or similar. You can also use a property.

What is a return type in C#?

Defining Methods in C# The return type is the data type of the value the method returns. If the method is not returning any values, then the return type is void. The parameter list refers to the type, order, and number of the parameters of a method.

What is the advantage of tuple as returning function argument?

Tuples provide a third way of returning multiple function values, one that combines aspects of the structure-based and on-the-fly options already mentioned. With tuples, you define the values to be returned as part of the function declaration, a bit like the out-parameter variation.
