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;
}
}
}
