ASP. C # int type has no change in the range of values in 32/64-bit environment

Recently in the study suddenly thought, I in 64-bit environment, int value range has changed? To test this result, I did the following:
1, Environment: Win7 flagship 64-bit +VS2010 SP1 (version number: 10.0.40219.1sp1rel) +.net 4.0.30319 Sp1rel
2. Code:

Code to copy code as follows
Using System;
Using System.Collections.Generic;
Using System.Linq;
Using System.Text;

Namespace ConsoleApplication1
{
Class Program
{
static void Main (string[] args)
{
Console.WriteLine ("Maximum value of type int:" +int. MaxValue);
Console.WriteLine ("Maximum value of Int64 type:" + int64.maxvalue);
Console.WriteLine (maximum value of "long": "+ Long.) Maxvalue.tostring ());
Console.WriteLine (maximum value for "ULONG type:" + ulong.) Maxvalue.tostring ());
Console.readkey ();

}
}
}

As can be seen, the program ConsoleApplication1.exe has been running in 64-bit state (not 64-bit *32 tag), but the int is still 2.1 billion (decimal does not count ^q^)
So, int in 64-bit environment, more than 2.1 billion will overflow
Other than that. NET Int64 and C # Long, the value is the same.

The difference between C # int Int32 Int64
The Int16 value type represents a signed integer value between 32768 and +32767.

The Int32 value type represents a signed integer value between -2,147 (Www.111cn.net) and 483,648 to +2,147,483,647.

The Int64 value type represents an integer value between 9,223,372,036,854,775,808 and +9,223,372,036,854,775,807.
