Interface implementation in C#

Question

Hi guys Can someone tell me why I am getting output as I am from I1 in both the cases explained below. interface I1 { void Cal1(); } interface I2 { void Cal1(); } class Program : I1  I2 { void I1 .Cal1() { Console .WriteLine( I am from I1 ); } void I2 .Cal1() { Console .WriteLine( I am from I2 ); } static void Main( string [] args) { I1 i1 = new Program (); i1.Cal1(); //Actual output: I am from I1 I1 i2 = new Program (); i2.Cal1(); //Actual output: I am from I1 Expecting I am from I2 Thanks Prakash

i2 needs to be a variable of the interface type I2 to get the output you're expecting. So you need: I2 i2 = new Program(); i2.Call();

Thanks Vulpes for pointing the mistake. It was typo from my side :)
