You need to separate the security-related exceptions from the other exceptions for database operations at
run time.
Which code segment should you use?
A. catch (System.Security.SecurityException ex)
{
//Handle all database security related exceptions.
}
B. catch (System.Data.SqlClient.SqlException ex)
{
for (int i = 0; i < ex.Errors.Count; i++){
if (ex.Errors[i].Class.ToString() == "14") {
//Handle all database security related exceptions.
}
else{
//Handle other exceptions
}
}
}
C. catch (System.Data.SqlClient.SqlException ex)
{
for (int i = 0; i < ex.Errors.Count; i++){
if (ex.Errors[i].Number == 14){
//Handle all database security related exceptions.
}
else{
//Handle other exceptions
}
}
}
D. catch (System.Data.SqlClient.SqlException ex)
{
for (int i = 0; i < ex.Errors.Count; i++){
if (ex.Errors[i].Message.Contains("Security")){

//Handle other exceptions
}
