Can we overload method as following?
Overloading Methods Method overloading can be achieved by the following: By changing the number of parameters in a method. By changing the order of parameters in a method. By using different data types for parameters.
What is an optional argument?
Optional arguments enable you to omit arguments for some parameters. Both techniques can be used with methods, indexers, constructors, and delegates. When you use named and optional arguments, the arguments are evaluated in the order in which they appear in the argument list, not the parameter list.
How do you call an overloaded constructor?
We can call an overloaded constructor from another constructor using this keyword but the constructor must be belong to the same class, because this keyword is pointing the members of same class in which this is used. This type of calling the overloaded constructor also termed as Constructor Chaining.
Does C# have optional?
C# Optional Arguments In C#, a method may contain required or optional parameters. It means we call method without passing the arguments. The optional parameter contains a default value in function definition. If we do not pass optional argument value at calling time, the default value is used.
Is it better to use optional parameters or method overload?
Closed 8 years ago. Since C# added optional parameters is it considered a better practice to use optional parameters or method overloads or is there a particular case where you would want to use one over the other. i.e a function w/ lots of parameters would be better suited w/ optional parameters?
When to use defaults or overloads in a method?
When a method overload normally performs the same thing with a different number of arguments then defaults will be used. When a method overload performs a function differently based on its parameters then overloading will continue to be used.
What happens when you overload a method in C #?
With an overload method you are stuck with either reading the documentation (if even available) or with directly navigating to the method’s definition (if available) and to the method that the overload wraps.
Why do we need optional and named parameters?
Part of the need for optional parameters and named parameters is because COM allowed optional and name parameters: Some APIs, most notably COM interfaces such as the Office automation APIs, are written specifically with named and optional parameters in mind.
