内容之余，把做工程过程中较好的内容段备份一下，下边内容是关于C# 自定义异常的方法演示及说明的内容，希望能对各位朋友有一些好处。

internal class Employee
{
public int ID { get; set; }
public string Name { get; set; }
public int CurrPay { get; set; }
public Employee() { }
public Employee(int id, string name, int currpay)
{
this.ID = id;
this.Name = name;
this.CurrPay = currpay;
}
public virtual void GiveBunus(int amount)
{
var pay = CurrPay;
this.CurrPay += amount;
if (CurrPay > 10000)
{
this.CurrPay = pay;
var ex = new PayOverflowException("The employee's max pay should be no more than 10000.");
throw ex;
}
}
}
class Program
{
static void Main(string[] args)
{
var emp = new Employee(10001, "Yilly", 8000);
try
{
emp.GiveBunus(3000);
}
catch (PayOverflowException ex)
{
Console.WriteLine("异常信息:{0}n发生于{1}类的{2}方法", ex.Message,
ex.TargetSite.DeclaringType, ex.TargetSite.Name);
try
{
var file = new FileStream(@"c:customerexception.txt", FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(file, ex);
file.Close();
}
catch (Exception ex1)
{
var inner = new PayOverflowException(ex.Message, ex1);
throw inner;
}
}
}
}
}

值得注意的是：在实例化的时候调用的是PayOverflowException(stringmessage,Exceptioninner)构造函数，如果本程序如果有其他程序在调用的时候,可以通过.InnerExcetpion的Message属性进行查看内部异常。
