C#入门11.5_预定义异常类(2)

InvalidCastException 类型的显示转换在运行时失败时，就会引发此异常

ArrayTypeMismatchException 当存储一个数组时，如果由于被存储的元素的实际类型与数组的实际类型不兼容而导致存储失败，就会引发此异常

ArithmeticException 算术运算期间异常发生的基类 

DivideByZeroException 试图除以零引发

OverflowException 溢出时引发 

FormatException 参数格式无效时引发

public static void RunSnippet()
	{
		bool mybool=true;
		try{
		char mychar=Convert.ToChar(mybool);
			Console.WriteLine(mychar);
		}
		catch(InvalidCastException ex)
		{
			Console.WriteLine(ex.Message.ToString());
		}
	}

public static void RunSnippet()
	{
		string[] mystr={"Cat","Dog","Pig"};
		object[] myobj=mystr;
		try
		{
			foreach(object outobj in myobj)
			{
				Console.WriteLine(outobj);
				Console.WriteLine(outobj.GetType());
				myobj[2]=13;
			}
		}
		catch(ArrayTypeMismatchException ex)
		{
			Console.WriteLine(ex.Message.ToString());
		}
		
		
	}

输出结果为：

Cat
System.String
试图访问类型与数组不兼容的元素。

public static void RunSnippet()
	{
		try
		{
			int num=10;
			Console.WriteLine(num/0);
		}
		catch(ArithmeticException ex)
		{
			Console.WriteLine(ex.Message.ToString());
		}
		
	}

public static void RunSnippet()
	{
		try
		{
			byte mybyte=Convert.ToByte(Console.ReadLine());
			Console.WriteLine(mybyte);
		}
		catch(DivideByZeroException ex)
		{
			Console.WriteLine(ex.Message.ToString());
		}
		
	}
