I'd say the biggest difference between the two languages is that C# is object oriented and C is not, which is basically a new way of programming. It might take some time to get used to it, but it is the way to go. Even scripting languages such as PHP have full OO support for some time now.

I'm not a fan of C# though. I don't use it so someone correct me if I'm wrong, but C# can only run on a Windows machine (they developed C#) or requires a third party software platform. If you want to learn a new language then I'd look into C++ (the improved version of C, also object oriented).

You are correct, C# is based on the .NET Framework therefore limited to Microsoft Windows platforms.

There are things link Mono, which can be cross platform.

right so c# is just like c++ in sense as it has been built from c and is just an extension.
