Remarks

This method is called by the base implementation of ToDisplayString and ToFullString when formatting property values to be placed in the output string.

The base implementation of this method gets the PropertyDescriptor for the property and uses its TypeConverter to produce a string representation, then it applies the following formatting rules:

If the property value is an Enum type that is marked with the FlagsAttribute, replace every comma (",") with a pipe ("|");
If the property value contains one or more single quotes ('), change each to two single quotation marks ('');
If the name/value separator or property entry separators (as specified in the constructor) contains one or more double quotes("), equal signs (=), or semicolons (;), then enclose the entire value in single quotation marks (').
