populate a dictionary using linq

Question

I have the following empty Dictionary

Dictionary<Guid, string> appTypeMap = new Dictionary<Guid, string>(); 

and the following list:

List<ApplicationType> allApplicationTypes = _applicationTypeService.GetAll() 

Application type is described as follows:

public class ApplicationType {    public Guid id {get; set;}    public String name {get; set;} } 

I want to populate the dictionary using LINQ.
How do I do that? Thanks.

Answer 1

appTypeMap = allApplicationTypes.ToDictionary(x => x.id, x => x.name); 

However, it will create a new dictionary, not fill yours.
