Is there a an easier way to initialize a List>, like a Dictionary?

Question

Actually I need something like List> but I want to be able to initialize it like dictionary (i.e. without writing new KeyVa

Answer 1

Because you do not have a dictionary you cannot use a dictionary initiailzer. You have a list so you could use a list initializer which will be the closest you could get:

var l = new List> 
{
    new KeyValuePair("key1", "value1"),
    new KeyValuePair("key2", "value2"),
};

Here's the minimum requirement for you to use dictionary initializer: the class must implement IEnumerable and the class must have a public method Add which takes 2 arguments (where the first argument represents the key and the second argument the value). So you could write a custom class which satisfies those requirements and you will be able to use the syntax you have shown in your question.
