C#/.NET: Assessing the SqlException severity

Posted by jpluimers on 2012/02/22

When handling SqlExceptions in C#, it is wise to assess the Class, as it indicates the severity.

Some classes are user error, others are fatal, etc.

This extension class will help you:

using System;
using System.Data.SqlClient;

namespace bo.MsSql
{
    /// <summary>
    /// see http://msdn.microsoft.com/en-us/library/ms164086.aspx
    /// </summary>
    public static class SqlExceptionSeverety
    {
        public static bool IsInformational(this SqlException sqlException)
        {
            return sqlException.Class < 10;
        }

        public static bool IsUserCorractable(this SqlException sqlException)
        {
            return (sqlException.Class >= 10) && (sqlException.Class < 17);
        }

        public static bool IsSoftwareError(this SqlException sqlException)
        {
            return (sqlException.Class >= 17) && (sqlException.Class < 20);
        }

        public static bool IsFatalSystemProblem(this SqlException sqlException)
        {
            return sqlException.Class >= 20;
        }
    }
}
