Converting string to lowercase in a dictionary.


Open original thread
I have a dictionary where both key and value are of type string.
Values are starting with capital letter like "Test".
I have to check whether this dictionary contains user input strings. User inputed strings can be of any case like mix of lower/upper case.

How do I convert dictionary values into lower case and compare against lower case converted user input values?


Dictionary <string,string> str = new Dictionary<string,string>();

now user input string can be "test". i will do it ToLower() on user input string. How do I use dictionary's contains method? how do I convert dictionary values into lower case and compare it? Remember I dont have key now..

Please suggest
