These Exceptions are thrown when certain errors are found in your C# code or in the methods you call.
All of these exceptions can be caught using a catch block in C#.
Here are some of the common Exceptions:
| EXCEPTION CLASS | CAUSE OF EXCEPTION |
| SystemException | It is used as a base class for other exceptions. Occurs on a failed run time check |
| AccessException | Occurs when failed to access a type member (method or a field) |
| ArgumentException | Occurs when an Argument to a method is invalid |
| ArgumentNullException | Occurs when a null argument is passed to a method which does not accept it |
| ArgumentOutofRangeException | Occurs when argument value is out of range |
| ArithmeticException | Occurs due to arithmetic over-flow or under-flow |
| ArrayTypeMismatchException | Occurs when you attempt to store different type of object in an array |
| BadImageFormatException | Occurs when the image is in the wrong format |
| CoreException | Its the BaseClass for the Exceptions thrown by runtime |
| DivideByZeroException | Occurs when you attempt to divide by zero |
| FormatException | Occurs if the format of an argument is wrong |
| IndexOutofRangeException | Occurs when an array index is out of range |
| InvalidCastException | Occurs when you attempt to cast to an invalid class |
| InvalidOperationException | Occurs if a method is called at an invalid time |
| NotFiniteNumberException | Occurs when a number is invalid |
| NotSupportedException | Occurs if a method is not implemented by a class |
| NullReferenceException | Occurs if you attempt to use an unassigned reference |
| OutofMemoryException | Occurs if the memory is not enough for execution |
| StackOverflowException | Occurs when stack overflows |
Thanks for the Info. I have a query on the order in which the exceptions should be caught. For ex, If I have a line of code which might throw 2-3 types of exceptions, is there any kind of order in which the exceptions should be caught?
ReplyDeleteCode snippet ex:
Try
{
string strText = strArrayValues[5].ToString();
}
Catch(...)
{
//catch code here
}
For the above line of code there might be the possibility of throwing index out of range or null reference or invalid cast exception. So is there any order in which we need to catch the type of exception occured from the code under try??
Thanks in Advance.
