Suppose you need several possible values for a variable, then it can be defined as an enumeration type. The reason for enumeration is to enumerate the possible values of variables or objects.For example, to make everyone more clear, for example,

First, what is reflection? Reflection provides encapsulated assembly, module, and type objects (type) You can use reflection to dynamically create an instance of the type, bind the type to an existing object, or obtain the type from the existing

A delegate is a type that safely encapsulates a method, similar to a function pointer in C and C ++. unlike C function pointers, delegates are object-oriented, type safe, and secure. the type of a delegate is defined by the name of the delegate. the

Most of the time, we need to get an ascii code of an English character, a unicode code of a Chinese character, or query the encoding of a character from the relevant encoding. Many people, especially those who learn C # From the VB program sequence,
