What Is C#?

C#, as mentioned earlier, is one of the languages you can use to create applications that will run in the .NET CLR. It is an evolution of the C and C++ languages and has been created by Microsoft specifically to work with the .NET platform. Because it is a recent development, the C# language has been designed with hindsight, taking into account many of the best features from other languages, while clearing up their problems.
Developing applications using C# is simpler than using C++, because the language syntax is simpler. Still, C# is a powerful language, and there is little you might want to do in C++ that you can ’ t do in C#. Having said that, those features of C# that parallel the more advanced features of C++, such as directly accessing and manipulating system memory, can only be carried out using code marked as unsafe . This advanced programmatic technique is potentially dangerous (hence its name), because it is possible to overwrite system – critical blocks of memory with potentially catastrophic results.
At times, C# code is slightly more verbose than C++. This is a consequence of C# being a type – safe language (unlike C++). In layperson ’ s terms, this means that once some data has been assigned to a type, it cannot subsequently transform itself into another unrelated type. Consequently, strict rules must be adhered to when converting between types, which means you will often need to write more code to carry out the same task in C# than you might write in C++, but you get two benefits: the code is more robust and debugging is simpler, and .NET can always track the type of a piece of data at any time. In C#, you therefore may not be able to do things such as “ take the region of memory 4 bytes into this data and 10 bytes long and interpret it as X, ” but that ’ s not necessarily a bad thing.
C# is just one of the languages available for .NET development, but it is certainly the best. It has the advantage of being the only language designed from the ground up for the .NET Framework and may be the principal language used in versions of .NET that are ported to other operating systems. To keep languages such as the .NET version of Visual Basic as similar as possible to their predecessors yet compliant with the CLR, certain features of the .NET code library are not fully supported. By contrast, C# can make use of every feature that the .NET Framework code library has to offer. The latest version of .NET includes several improvements to the C# language, partly in response to requests from developers, making it even more powerful.
