Question

some simple types like int, string , ....are easy to realize that they are ValueTypes Or RefrenceTypes. But I wanna to know is there any way to distinguish?

Answer 1

Strings are not value types.

Here is a list of the most commonly used value types:

• bool (System.Boolean)
• byte (System.Byte)
• char (System.Char)
• decimal (System.Decimal)
• double (System.Double)
• float (System.Single)
• int (System.Int32)
• long (System.Int64)
• sbyte (System.SByte)
• short (System.Int16)
• uint (System.UInt32)
• ulong (System.UInt64)
• ushort (System.UInt16)
• System.DateTime

Besides those:

• Any type that is an enum
• Any type that is a struct

All other types are reference types.
