Question: Why strings are immutable?

Answer: 1) In VB6.0 and c++ strings are simple array of bytes, but in .Net it is class System.String and is immutable.

2) A string is a sequential collection of Unicode characters, which usually is used to represent text. A String, on the other hand, is a .NET Framework class (System.String) that represents a Unicode string with a sequential collection of System.Char structure.
