The exception handling techniques very use full to display
the errors in meaningfull way.
The syntax of exception handling as follows.
try
{
}
catch(Exception )
{
}
catch(Exception )
{
}
finally
{
}
Here the set of codes executed if any error found in try
block the catch block will be executed.We may have any
number of exception in catch but it will only one executed
according to the type of error.But the finally block must
executed automatically whether error found or not.
try
{
SqlConnection con = new SqlConnection();
con.ConnectionString =" ----";
String sql;
sql = "---";
SqlCommand cmd = new SqlCommand(sql,con);
cmd.CommandType = CommandType.Text;
cmd.ExectuteNonQuery();
}
catch(FileNotFoundException e)
{
Console.WriteLine("Error:"+e.Message);
}
catch(SqlException ee)
{
Console.WriteLine("Error:"+ee.Message);
}
finally
{
Console.WriteLine("This program written by S.Senthil
umar");
}

Sorry, i think th above answer is not clear.
In ASP.Net Exception Handling is an one of an excellent
concept given by Microsoft.
Now, let me explain you how to handle exceptions in ASP.Net?
If any exceptiuons get raised in ASP.Net it will effect to
the whole project i mean to say , if we get exception we get
a error page in the browser while loading..and that is
viewable
for the client and the user. when it is like that what is
the use of using ASP.Net.
so, to avoid this problem we have to create an Customized
Error Page and then goto web.config and write a parameter in
CustomErrors tag as
defaultRedirect = "CustomErrorPage.aspx"
and according to the security change the
mode="On/Off/RemoteOnly"
