ผมอยากทราบว่า Exception ที่ใช้บ่อยในการเขียนโปรแกรม C# มีอะไรบ้างครับ

try
{
	// The set of code and function here
	// reviewed by an Experienced lead.
}
catch (System.FileNotFoundException Ex)
{
	//File Not Found Exception is Different from Divide by zero.
	//Look at the Inheritance hierarchy in MSDN for FileNotFoundException
	//and DivideByZeroException.
	//So I don't care Which one First, FileNotFond or DivideByZero
}
catch( System.DivideByZeroException Ex) 
{
	//Divide by Zero Exception. Need More Specialized care
}
catch (System.ArithmeticException Ex)
{
	// For any ArithmaticException except DivideByZero. Because I already handled it 
	// before this catch statement
}
catch(System.Exception Ex)
{
	//I am not expecting that this would Occur. As per my Lead
	//I placed it for safe to handle any Exception in the world 
	// That derived from Exception.
}
finally
{
	//Clean-up code
}
