整数类型的取值范围:
SByte: -128~127
Byte: 0~255
Int16: -32768~32767
UInt16: 0~65535
Int32: -2147483648~2147483647
UInt32: 0~4294967295
Int64: -9223372036854775808~9223372036854775807
UInt64: 0~18446744073709551615

如果类型取值超出了取值范围，程序在运行时就会发生溢出。
Byte溢出代码：
复制代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace IntegrateOverflow
{
class Program
{
static void Main(string[] args)
{
byte b = 100;
b = (byte)(b + 200); // 溢出
Console.WriteLine(b);
}
}
}
