Consider the code below.

Public interface IstringInterface

{ String str {get;}

}

Public class StringClass: IstringInterface

{ //Implicit implementation

Public string str

{ Return “Implicit interface Implementation” ;

}

//explicit implemenatation

Public string IstringInterface.str

{ Return “Explicit interface Implementation” ;

}

}

Main()

{ StringClass obj = new StringClass();

//Implicit

Obj.str // work fine Calling way 1

(IstringInterface (Obj)).str // works fine calling way 2

//Explicit

Obj.str// not works Calling way 1

(IstringInterface (Obj)).str // // works fine calling way 2

}

For the implicit implementation Calling way 1 and Calling way 2 works fine. But Here, from the yellow line, if we use the explicit implementation then we will not be able to call the method directly, and only the calling way 2 will work.
