That is, the caller can modify the value returned by a method, and that change is reflected in the state of the object in the called method. Using some other features offered by C#, we can return multiple values to the caller method. If your two values are logically attributes of some larger, aggregate type, you can use a struct type to return a single object with multiple attributes, such as Pointer : Pointer to a basic data type variable (like .

Pointers in C We can use pointers in C to return more than one value from the function by passing pointers as function parameters and use them to set multiple values, which will then have visibility in the caller function. We can return multiple values from the function using the array but the limitation is that all values should have the same type. All the parts . This may surprise you, however, since you don't actually tell the function to return (1, 2, 3). Then the operations which need to be done on c and d are performed. More Detail. c# can a method return multiple functions. multi variable assignment cpp. Parameters passed by pointers can be used to "return" values to the caller.

However, there's nothing in the rules to say that the value returned can't itself be a group or list of things. When calling a function, to save these values, you must use the following syntax: local a, b, c = triple (5) Which will result in a = b = c = 5 in this case. Nullable<T>.Value gets the value of an underlying type if HasValue is true. This means that the ReturnMultipleValues () function will return 3 values with the first two values of string data-type and the last value of int data-type. Shop. Reference return values.

To keep examples simple we'll use pair but everything that follows is also valid for std::tuples for more than two returned values. try get value but return multiple values c#. Since the only data type in J is array (this is an oversimplification, from some perspectives - but those issues are out of scope for this task), this is sort of like asking how to return only one value in another language.
