Second, data conversion

① value type:

Shaping: Int (Int32), Long (Int64), float: float (single);d ouble (double);d ecimal (decimal);

Character type: char (char), Boolean: bool (Boolean), DateTime: Date, enum type: enum;

Structure type: struct;

② reference types

String Type: Strings (String)

③ Constants and variables (cannot be assigned, only values, const)

④ Basic Type conversions

1. Auto-Convert (implicit conversion): value type → reference type (added later.) Tostring)
2. Cast (explicit conversion): decimal-to-integer && reference-to-value class (1. With (), 2. With convert 3. Using the parse [common])
