Class ExceptionLoggingHelper

Utility class for logging exceptions.

Inheritance

Object

ExceptionLoggingHelper

Namespace: TehGM.Wolfringo.Utilities

Assembly: Wolfringo.Core.dll

Syntax

public static class ExceptionLoggingHelper

Remarks

By default, if exception is caught, and exception is logged inside of the handling block, the log scope will be lost. The way around this is to log the exception using `when` keyword.
This class contains methods that return true so they can be used with `when` syntax.

Usage sample:

try
{
    // ...
}
catch (Exception ex) when (ex.LogAsError(_log, "Exception has occured")) { }
