PropertyFilter Class

Trace filter that filters based on the value of a property.


Note: The functionality of this filter is superseeded by ExpressionFilter and it is only maintained for backwards compatibility.

The initializeData for this filter contains a single property comparison, e.g. initializeData="Id == 1".

The value must consist of a property name from one of the values supported by TraceFormatter, the C# equality operator (double equals signs) and then a single value. Matching quotes around the value are removed and whitespace (outside of any quotes) is ignored, e.g. "Id == 1" and " Id == '1' " are equivalent.

The property is converted to a string using TraceFormatter and then compared with the value.
