Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ILog. When you use instance method syntax to call this method, omit the first parameter. For more information, see Online

Extension Methods (Visual Basic) or Online

Extension Methods (C# Programming Guide).

Remarks

This method first checks if this logger is ERROR enabled by reading the value property. This check happens always and does not depend on the implementation. If this logger is ERROR enabled, then it converts the message object (passed as parameter) to a string by invoking the appropriate IObjectRenderer. It then proceeds to call all the registered appenders in this logger and also higher in the hierarchy depending on the value of the additivity flag.

WARNING Note that passing an Online Exception to this method will print the name of the Online Exception but no stack trace. To print a stack trace use the ErrorExt(ILog, Object, Exception) form instead.
