byte
ushort
uint
ulong
float
double
decimal
bool
char
string
sbyte, short, int and long are singed integer type.
byte, ushort, unit and ulong are unsigned integer types
Predefined C# types have alias in System namespace.
For example, the alias for int type is System.Int32
using System;
class Program
{
static void Main(string[] args)
{
int i = 5;
System.Int32 j = 10;
Console.WriteLine(i);
Console.WriteLine(j);
}
}
The output:
5
10
