Question

I have a C# dictionary, Dictionary<Guid, MyObject> that I need to be filtered based on a property of MyObject.

For example, I want to remove all records from the dictionary where MyObject.BooleanProperty = false. What is the best way of acheiving this?

Answer 1

Since Dictionary implements IEnumerable<KeyValuePair<Key, Value>>, you can just use Where:

var matches = dictionary.Where(kvp => !kvp.Value.BooleanProperty);

To recreate a new dictionary if you need it, use the ToDictionary method.
