Question

Error Cannot implicitly convert type 'string[]' to 'System.Collections.Generic.List<string>' 

The above error is caused when I call a method to a web service

List<string> bob = myService.GetAllList(); 

Where: GetAllList =

[WebMethod]         public List<string> GetAllList()         {              List<string> list ....             return list;         } 

I have rebuilt the whole solution, updated the service references and still I get a cast exception any ideas?

Answer 1

you need to do this:

List<string> bob = new List<string>(myService.GetAllList()); 

An overload for the constructor of a generic list takes an IEnumerable of the specified type to initialize the array. You can not, like the exception states, implicitly cast it staright to that type.
