## C＃用户定义的异常 **(**C\# User-defined exceptions**)** ##

In C\#, we can **create our exception class by inheriting base class Exception**. Because as we know that **Exception** is the base class for all types of exceptions in C\#.

在C＃中，我们可以**通过继承基类Exception**来**创建异常类** 。 因为我们知道**Exception**是C＃中所有类型的异常的基类。

Here is the example of a **user-defined exception**,

这是**用户定义的异常**的示例，

using System;
    
    class UserDefineException: Exception
    {
        
    
        public UserDefineException(string str)
        {
        
            Console.WriteLine(str);
        }
    }
    
    class Program
    {
        
        static void Main()
        {
        
            UserDefineException M = new UserDefineException("User Define Exception");
    
            try
            {
        
                throw M;
            }
            catch (Exception e)
            {
        
                Console.WriteLine(e.Message);
            }
        }
    }

**Output**

**输出量**

User Define Exception
    Exception of type 'UserDefineException' was thrown.

In the above program, we created a class **"UserDefineException"** by inheriting the base class **"Exception"** and created a parameterized constructor, through the user-defined object in **"try block"** of **"Program"** class, it is caught in **"catch block"**.

在上面的程序中，我们通过继承基类**“ Exception”**创建了一个**“ UserDefineException”**类，并通过**“ Program”**类的**“ try块”**中的用户定义对象创建了一个参数化构造函数，将其捕获在**“ catch块”中“** 。
