Public propertyNumberGets a number that identifies the type of error.
Public propertyProcedureGets the name of the stored procedure or remote procedure call (RPC) that generated the error.
Public propertyServerGets the name of the instance of SQL Server that generated the error.
Public propertySourceGets the name of the provider that generated the error.

This class is created by the .NET Framework Data Provider for SQL Server when an error occurs. An instance of SqlError is created and managed by the SqlErrorCollection, which in turn is created by the SqlException class.

Messages with a severity level of 10 or less are informational and indicate problems caused by mistakes in information that a user has entered. Severity levels from 11 through 16 are generated by the user, and can be corrected by the user. Severity levels from 17 through 25 indicate software or hardware errors. When a level 17, 18, or 19 error occurs, you can continue working, although you might not be able to execute a particular statement.

The SqlConnection remains open when the severity level is 19 or less. When the severity level is 20 or greater, the server usually closes the SqlConnection. However, the user can reopen the connection and continue. In both cases, a SqlException is generated by the method executing the command.

For more information on errors generated by SQL Server, see Cause and Resolution of Database Engine Errors. For more information about severity levels, see Database Engine Error Severities.
