This seemed related, but I didn't understand it properly: c# Dictionary: making the Key case-insensitive through declarations
It is indeed related. The solution is to tell the dictionary instance not to use the standard string compare method (which is case sensitive) but rather to use a case insensitive one. This is done using the appropriate constructor:
var dict = new Dictionary<string, YourClass>( StringComparer.InvariantCultureIgnoreCase);
The constructor expects an
IEqualityComparer which tells the dictionary how to compare keys.
StringComparer.InvariantCultureIgnoreCase gives you an
IEqualityComparer instance which compares strings in a case-insensitive manner.
