Positional vs. Named Parameters

In the preceding example, 

RemarkAttribute

 was initialized by passing the description

RemarkAttribute( )

 is called a 

positional parameter.

 This term relates to the fact 

that the argument is linked to a parameter by its position in the argument list. This is the way 

that all methods and constructors work in C#. For example, given a method called 

test( )

,

declared as shown here:

void test(int a, double b, string c)

test( )

test(10, 1.1, "hello");

passes 10 to
