Unsafe code( pointers ), shows and example of a copy, where a byte* is casted to a int* and then dereferenced. Such operation in c produces undefined behavior(

  There is no concept of "dereferencing" in C# because there are no pointers. Technically it is possible to force the environment to allow you to write unsafe code but I've never seen this in reality and I'm having a hard imagining where it would be useful.

    One thing where it is useful is manipulating image data. You can get a raw pointer from the Bitmap class you can then manipulate with unsafe code which is orders of magnitude faster than the normal variant. Basically you're saying, for a single method or a block of code "Please turn off all safety nets, but only for these 20 lines". The places where it's useful or necessary are quite few, though.
