I'm trying to catch the exception thrown when I insert a already existing user with the given username into my database. As the title says then I'm using EF. The only exception that's thrown when I try to insert the user into to db is a "UpdateException" - How can I extract this exception to identify whether its a duplicate exception or something else?
catch (UpdateException ex)
{
SqlException innerException = ex.InnerException as SqlException;
if (innerException != null && innerException.Number == ??????)
{
// handle exception here..
}
else
{
throw;
}
}
Put the correct number at ??????
that corresponds to unique constraint violation (I don't know it from the top of my head).
