I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component public class AllViewComponent : ViewComponent { private readonly UserManager<ApplicationUser> _userManager; public AllViewComponent(UserManager<ApplicationUser> userManager) { _userManager = userManager; } public async Task<IViewComponentResult> InvokeAsync() { List<StudentViewModel> allUsers = new List<StudentViewModel>(); var items = await _userManager.Users.ToListAsync(); foreach (var item in items) { allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email }); }
Introduction
Definition : “Basic data types are those that are not composed of other data types.Primitive Data types are:
- int
- char
- float
- double
- void
fundamental data types.
int
It is a keyword which is used to define integer numbers. Normally they are associated with theVariables to store singed integer values in memory locations. That is, using this data type both
Positive and negative numbers can be stored in the memory . To represent only unsigned numbers
it is normally associated with a qualifier unsigned.
For example, unsigned int is used to define only positive numbers. Negative numbers cannot be
Stored if a variable is associated with unsigned int. the size and the range of integer vary from
Machine to machine as shown below:

Float
It is a keyword which is used to define floating point numbers. The floating point numbers are Also called real numbers. Normally they are associated with the variables (also called identifiers) To store floating point numbers in memory locations. That is , using this data type both positive And negative floating point numbers can be stored in the memory.
Double
It is a keyword which is used to define high precision floating point numbers Normally they are Associated with the variables to store large floating point numbers in memory locations. That is, Using this data type both positive and negative large floating point numbers can be stored in the Memory.
Char
It is a keyword which is used to define single character or a sequence of character called string.
Normally , They are associated with the variables to store a character or a string in memory
Locations. Each character stored in the memory is associated with a unique value called an ASCII
(American standard Code For Information Interchange) value.
Void
It is an empty data type. It is normally used in functions to indicate that the function does not
Return any value. Since no value is associated with this data type, it does not occupy any space
in the memory. Normally, it is not associated any variable (except pointers).
