These are the most basic data types and belong to the most basic elements of a language. I suggest you find the basic data to see the best. For example, the variable defined by the int keyword is actually a number ranging from -32768 to 32767. Here is a brief introduction to the basic data types in C#:

Boolean system. Boolean algebra system

4-byte 32-bit Boolean variable logical value true or false default value false

Byte system. byte

1Byte 8bit unsigned integer unsigned byte storage value range 0~255 Default value 0.

Sbyte system SByte 1 byte

8-8 bit signed integer signed byte storage value range-128~ 127 The default value is 0.

Charging system. tea

2 bytes 16-bit unsigned Unicode character default value' \0'

Decimal system decimal

16 bytes 128-bit decimal number follows the rounding rule. Decimal number 28 is usually used to calculate the default value of 0.0m in finance.

Double system. double；twofold

The default value of 8-byte 64-bit double-precision floating-point type is 0.0d

Floating system. single

The default value of 4-byte 32-bit single-precision floating-point type is 0.0f

Int system. Int32

4-byte 32-bit signed integer default value 0

Uint system UInt32

4-byte 32-bit unsigned integer default value 0

Long system. Int64

8-byte 64-bit signed integer default value 0

Ulong system UInt64

8-byte 64-bit unsigned integer default value 0

Object system. target

Pointing to the class instance reference default value null

Short system. Int 16

2 bytes 16-bit signed integer Default value is 0.

Ushort system UInt 16

2 bytes 16-bit unsigned integer Default value is 0.

String system. line

Pointing to string object reference default value null
