Can anyone explain me this.

I think it is because String.Compare () returns 0 or 1 which are nothing but of type int32.

I think surekha is right.

In this type ,we write
string.compare and use GetType() method then we find----System.Int32
string.Equals and use GetType() method then we find---System.Boolean
string.Join and use GetType() method then we find----System.System
Always remember
string.compare and use GetType() method then we find----System.Int32
string.Equals and use GetType() method then we find---System.Boolean
string.Join and use GetType() method then we find----System.System

You are right Jay but its not System.System for string.Join...it is System.string...

I'm just curious it about the result of the comparison, String.Compare(str, "Hello World?" ) , it it returned -1?
Can anyone please explain me this?

Compare method has always return type is integer.

String comparison performs a case-sensitive comparison.
Assume s1 and s2 are two strings,
If s1 is equal to s2 then it returns zero.
If s1 is greater than s2 then it returns 1.
If s1 is less than s2 then it return -1.

public static int Compare(string strA, string strB)
Member of System.String
..................
return type of Compare method is int &
public Type GetType()
Return Value
Type: System.Type
..............................
The exact runtime type of the current instance.

Compare() methods always returns Int32 type because Int32 shows lexical relationship between the two comparands.
No matter what the string is, it will still return Int32 as answer.
For example :-
string str= null;
Console.WriteLine( String.Compare(str, null ).GetType());
Return : System.Int32
Note : Those who are thinking that first string will be compared and if matched/unmatched Boolean value will be returned and then it's type will be returned on the basis of 0/1. No such thing will happen here guyzzz !!.
Thank You :).
