1. If our program does not catch an exception then the .NET CLR catches it.
2. It is possible to create user-defined exceptions.
3. All types of exceptions can be caught using the Exception class.
4. CLRExceptions is the base class for all exception classes.
5. For every try block there must be a corresponding finally block.
Unhandled Exception: System.lndexOutOfRangeException:
Index was outside the bounds of the array:
at CompSciBitsConsoleApplication.MyProgram.SetVal(Int32 index, Int32 val) in
D:\Sample\CompSciBitsConsoleApplication\MyProgram.cs:line 26
at CompSciBitsConsoleApplication.MyProgram.Main(String[] args) in
D:\Sample\CompSciBitsConsoleApplication\MyProgram.cs:line 20
1. The CLR failed to handle the exception.
2. The class MyProgram belongs to the namespace MyProgram.
3. The function SetVal() was called from Main() in line number 20.
4. The exception occurred in line number 26 in the function SetVal()
5. The runtime exception occurred in the project CompSciBitsConsoleApplication.
using System;
namespace CompSciBitsConsoleApplication
{
class MyProgram
{
static void Main(string[] args)
{
int index;
int val = 44;
int[] a = new int[5];
try
{
Console.Write("Enter a number:");
index = Convert.Tolnt32(Console.ReadLine());
a[index] = val;
}
catch(FormatException e)
{
Console.Write("Bad Format");
}
catch(IndexOutOfRangeException e)
{
Console.Write("Index out of bounds");
}
Console.Write("Remaining program");
}
}
}Unhandled Exception: System.lndexOutOfRangeException:
Index was outside the bounds of the array.
at CompSciBitsConsoleApplication.Program.Main(String[] args) in
D:\ConsoleApplication\Program.cs:line 14
1.The program did not handle an exception called IndexOutOfRangeException.
2. The program execution continued after the exception occurred.
3. The exception occurred in line number 14.
4. In line number 14, the program attempted to access an array element which was beyond the bounds of the array.
5. The CLR could not handle the exception.
1. try blocks cannot be nested.
2. In one function, there can be only one try block.
3. An exception must be caught in the same function in which it is thrown.
4. All values set up in the exception object are available in the catch block.
5. While throwing a user-defined exception multiple values can be set in the exception, object.
using System;
namespace CompSciBitsConsoleApplication
{
class MyProgram
{
static void Main (string[] args)
{
int index;
int val = 66;
int[] a = new int[5];
try
{
Consote.Write("Enter a number: ");
index = Convert.ToInt32(Console.ReadLine());
a[index] = val;
}
catch(Exception e)
{
Console.Write("Exception occurred ");
}
Console.Write("Remaining program ");
}
}
}
