Specifies whether to perfom a case-sensitive comparison.
true if a case-insensitive comparison will be performed; otherwise, false.
By default, this property is set to false.
When defining the RuleStringComparisonAttribute in code, the value for the IgnoreCase property is passed as a named parameter. This means that you do not have to specify it. However, when specifying, use the following format: IgnoreCase = true (IgnoreCase := True, in Visual Basic).
