Select all keys except some key

Question

I Only know one key from dictionary and I want to Select all other key that are present.

I don't want to remove the KeyValue pair that I know but want to select rest.

For example, I have:

Key:Health
Value: 123

Key:Vision
Value: 345

Key:Dental
value:567

and I know that Health will be there. So I want to select all other Keyvalue pairs except Key:Health

Could any one suggest a C# code to implement this ?

Answer 1

var allKeyValuesButHealth = dict.Where(kv => kv.Key != "Health");

Since this is a deferred executed LINQ query it's a good idea to materialize it with ToList, ToArray or even ToDictionary if you want to use it multiple times.
