Focus:1. Each time the function is called, its formal parameters are recreated and the parameters are initialized with the passed-in arguments.Note: the mechanism of formal parameter initialization is the same as the initialization of variables. 2. The type of the formal parameter determines how the formal parameter interacts with the argument.(References , bindings, non-reference, copy)3. Arguments are:
C #4.0 named parameters and optional parameters,
Default parameters in C #4.0
C #4.0 now supports default parameters for methods, constructors, and indexers (Note: VB supports default parameters for years ).
When the default value of a parameter is specified as a part of the

1. Dynamic expandoobjectAnyone familiar with JS knows that JS can be written like this:
VaR T = new object (); T. ABC = 'something'; T. value = 243;
We can also use this JS Dynamic Language Feature in C #, provided that a variable is declared as the expandoobject type. For example:
Static void main (string [] ARGs) {dynamic T = new expandoobject (); T. ABC = "ABC"; T. value = 10000; console. writeline ("T's abc = {0}, t's value = {1}", T. ABC, T. value); console. readline ();}

We said it earlier. In the C language, array parameters are degraded to pointers. So what is this for? InThe C language only passes the parameter as a copy of the value, and when passing an array to the function, instead of copying an entire array into the function, the array name is treated as a constant pointer to the first element address of the array. Then, when the C language was set up, it was mainly used for UNIX operating systems, and UNIX was
