Difference between Class and Structure

CLASSSTRUCTURE
Classes are of reference types.Structs are of value types.
All the reference types are allocated
 on heap memory.		All the value types are allocated on
stack memory.
Allocation of large reference type
is cheaper than allocation of large
 value type.		Allocation and de-allocation is cheaper
in value type as compare to reference type.
Class has limitless features.Struct has limited features.
Class is generally used in large programs.Struct are used in small programs.
Classes can contain constructor or
 destructor.		Structure does not contain constructor
or destructor.
Classes used new keyword for
creating instances.		Struct can create an instance, without
new keyword.
A Class can inherit from another class.A Struct is not allowed to inherit from
another struct or class.
The data member of a class can be
protected.		The data member of struct can’t be
protected.
Function member of the class can be
 virtual or abstract.		Function member of the struct cannot
 be virtual or abstract.
Two variable of class can contain
 the reference of the same
object and any operation
on one variable can affect another
variable.		Each variable in struct contains its own
copy of data(except in ref and out
parameter variable) and any operation
on one variable can not effect another
 variable.

View vs Partial View MVC

The primary difference is that a Partial View is designed to be rendered within other full Views and as a result it will not contain all of the markup that a full View might ( since it is designed to work within other Views ). For example, a normal View might look like this and contain all of the elements present in a traditional HTML page :  <!DOCTYPE html> <html> <head> <meta charset = utf-8 /> <title> Example </title> </head> <body> <!-- Your Content Here --> </body> </html> where as a Partial View might only contain a small section that it needs to render and since it should be displayed within an existing View, it won't require the necessary tags like <head>, <html>, etc. because it is implied that these should already be present when a Partial View is rendered. An example partial View might look like this :  <div> <!-- Example --> <ul> ...
