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。

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。
