why we declare class name as data type in C# as well as method return type as class name.

e.g
private TraceViewContainerModel cmTraceviewContainer;
internal Device device;

here TraceViewContainerModel and Device is class name.

public TraceViewViewModel AddTraceObject(TraceObject trc, bool isNew)
{
bool useCurrentAxisSettings = false;
ZedGraph.Scale xaxisScale = null;

Again TraceViewViewModel this is class which is declare as return type in another class.

Hi Ravi.

It a object oriented programming language.
If you are dealing with any string type functionality the the return type of your method should be string as below.


public string SomeMethod()
{
string s="sridhar thota";
return s;// am returning string i.e., "sridhar thota"
}

But if you are returning a object type i.e., fields more than two or three of a classlike below, then we have to use class name as return type.


public class TraceViewViewModel 
{
public int traceid {get;set;}
public string tarcename {get;set;}
}
public TraceViewViewModel SomeMethod()
{
TraceViewViewModel obj=new TraceViewViewModel ();
obj.traceid =1;
obj.tarcename ="test";
return obj;// am returning obj i.e., TraceViewViewModel object so we will declare return type method as class name.
}

Hope you got some idea.
