What is the method for invoking a scalar-valued function in C# and retrieving its value?

edit

To invoke a scalar-valued function in C# and retrieve its value, we can use the following syntax:

// assume we have a function named "myFunction" that returns a scalar value
int myResult = myFunction(); // invoke the function and store the result in a variable

This assumes that the function returns an integer. If the return type is different, you should replace int with the appropriate type.
