The types of the C # language are divided into two main classes: value types (values type) and reference types (reference type). Both value types and reference types can be generic types (generic type), and generic types take one or more type
Value range of each data type
The bool type is Boolean and occupies 1 byte. The value is 0 or 1.
The BOOL type is int type. Generally, it occupies 4 bytes. The value is TRUE/FALSE/ERROR.
Sbyte is a signed 8-digit integer, which occupies 1 byte.

Some data types are often used in code writing, such as int and string. For example, we define an integer below:
int a =0;
We can also define it in the following

Some data classes are very commonly used in development, so many compilers allow the code to operate on them with simplified syntax. For example, you can use the following syntax to assign an integer:
System.Int32 a = new System.Int32();
int a = 0
