Remarks
This method is called by the base implementation of ToDisplayString and ToSafeString 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, and 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 quotation marks ('), change each to two single quotation marks ('').
If the property value contains the key/value separator or property entry separator (as specified in the constructor), double quotation marks ("), a single quotation mark ('), or starts or ends with spaces, enclose the entire value in single quotation marks (').
