When I started learning C# half the time I was trying to find Java equivalents so that I can learn effectively, leveraging my existing Java skills. At times I was so frustrated by my knowledge or lack there of. I'm penning this piece in the hope that my experience might help Java programmers to learn Java's new cousin (or villain according to some view points!). I'll only deal with those functionalities which are present in Java but are modified / changed completely in...

When you create a C# class, you can make it available as a COM object to code outside of the VS.NET framework. This is done through use of the utility REGASM. REGASM creates a COM Type Library that describes the COM aspects of the class for use by both early binding in C++ (through #import directives) and late binding systems (such as VB6, through project references), and registers the COM class in the Registry under the HKLMSoftwareCLSID hierarchy. However, every...

Interface implementation can be confusing... I see a feature in C# that can be very confusing. In the example below we have a class (Test) that implements 2 interfaces (I1 and I2). So the logic says that we should have implementations in the class Test for both MyFunction() methods from I1 and I2. BUT! As you see in the example below everything works fine with only 1 implementation. This is not as correct as we expect, because we can't be sure which of the two interfaces...

In C# also inner classes are possible. The program code demonstrates the implementation of inner classes and structures in classes. If we want to create an instance out side the class the inner class and inner structure should be public. Unlike java there will only one EXE is created, but in java more than one class files will create. The following program is self explanatory with proper output //Here Demonstrating class ,innerclass and inner structure //Demonstrating...
