populate a dictionary using linq

Question

I have the following empty Dictionary ``` Dictionary appTypeMap = new Dictionary(); ``` and the following list: ``` List 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.

Accepted Answer

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

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