In C # what is the difference between string and string

In C # there is string and there is System.String .

What is the difference between the two? It is considered better to use this other. Are there any hidden dangers when mixing their use?

If they are the same, then why are they both? Why not just one or the other?

Answer 1

System.String is the name of the real CLR.NET class, just as System.Int32 is the real name of this class. But C # developers wanted it to be very similar to C and C ++, where the native types (e.g. int ) are in lower case, so they added aliases for the main native types.

Answer 2
