Add comparison option to GetParametersValue(s)

[ghost]

I found having a case insensitive option to be useful where API contracts were poorly defined.

This indeed looks like a useful improvement but, if you don't mind, please raise an issue to describe the improvement you are submitting, why you thing its helpful, etc.

The issue is particularly important because I reference them in the release notes) to let developers know what new in each released version.

Thanks

oh and kudos for including unit test to prove that your improvement works as intended!

Looks good to me!

Thank you for your contribution.

I have raised an issue to cover this.

You should note that while this change is non-breaking when compiling code it is breaking if consumers just drop in a new DLL without recompiling as the additional optional argument will cause the symbol table to change. If you want to ensure this is non-breaking in all circumstances we can use method overloads without default value so that the original method signatures would also remain in the symbol table.

//Original signatures
GetParameterValue(string) 
GetParameterValues(string) 

//Additional new signatures
GetParameterValue(string, StringComparison) 
GetParameterValues(string, StringComparison)
