C# Default Parameter Value
Default Parameter Value
You can also use a default parameter value, by using the equals sign (=).
If we call the method without an argument, it uses the default value ("Norway"):
Example
static void MyMethod(string country = "Norway")
{
Console.WriteLine(country);
}
static void Main(string[] args)
{
MyMethod("Sweden");
MyMethod("India");
MyMethod();
MyMethod("USA");
}
// Sweden
// India
// Norway
// USA
A parameter with a default value, is often known as an "optional parameter". From the example above, country is an optional parameter and "Norway" is the default value.
