Is there a Integer class in c#?

Question

We have Integer class in JAVA, but I couldn't find any equivalent class in C#? Does c# have any equivalent? If not, how do I get JAVA Integer class behavior in c#?

Why do I need this?

It is because I'm trying to migrate JAVA code to c# code. If there is an equivalent way, then code migration would be easier. To addon, I need to store references of the Integer and I don't think I can create reference of int or Int32.

Answer 1

C# has a unified type system, so int can be implicitly boxed into an object reference. The only reason Integer exists in Java is so that it can be converted to an object reference and stored in references to be used in other container classes.

Since C# can do that without another type, there's no corresponding class to Integer.

Answer 2

Code migration won´t work out of the box for any type of language without any manual changes. There are things such as a class Integer that simply does not exist within (C# why should it anyway, see recursives answer), so you´d have to do some work on your own. The nearest equivalent to what you´re after is Int32 or its alias int. However you may of course write your own wrapper-class:

    public class Integer     {         public int Value { get; set; }           public Integer() { }         public Integer( int value ) { Value = value; }           // Custom cast from "int":         public static implicit operator Integer( Int32 x ) { return new Integer( x ); }          // Custom cast to "int":         public static implicit operator Int32( Integer x ) { return x.Value; }           public override string ToString()         {             return string.Format( "Integer({0})", Value );         }     }
