C # Data type (only 5 kinds of course)

int: Represents an integral type with range storage values (2,147,483,648 to 2,147,483,647, 10 digits) inverted: 3, 5, 100, 10, etc.

int number;//A numeric type variable that declares an integer
Number = 1000;
Console.WriteLine (number); //Note this cannot be quoted here

Double represents a decimal type, the range stores values ±5.0x10−324 to ±1.7x10308, such as: 3.14, 1.5, 5.0, etc.

Double pi; //Declare a decimal number type variable
PI = 3.14; //The value can also be integer but must be appended. 0 as 3.0
Console.WriteLine (PI);

char denotes a single character type that is inverted as: ' Male ' a ' a ', etc. note declaring a variable must be a single quotation mark when assigning a value

char sex; //Declare a variable of character type
sex = ' male ';//The variable value of a character type must be enclosed in single quotation marks
Console.WriteLine (Sex);

String represents 0 or more strings that are inverted as: "Computer" "Hello World" "Zhangsan" note when declaring variable assignments, be sure to enclose the value in double quotation marks

String chinaname;//A variable that declares a string
Chinaname = "by three"; the//variable value must be double-quoted and can be 0 or more numeric characters
Console.WriteLine (Chinaname);

Decimal means that a variable of money is higher than a double, for example 5.65 1000 100 Note that if the money has a decimal number, it must be added after the assignment of M

Decimal money;
Money = 5.65m;
Console.WriteLine (Money);
Console.readkey ()

Note Writing a number in a C # development environment that has a decimal type is just a double type, with a decimal followed by M is the decimal type if the money is sometimes an integer then it can be used without m because the integral type is implicitly converted to decimal, and evaluates to decimal. Therefore, you can initialize decimal variables with integers without using suffixes
