I have created a list collection and I am trying to pass a string back to it. It a data member in a WCF class.
Public List<HumDTO> HumID
{

    get;
    set;

}

when I get a instance of the class"

QueryDTO aDTO = new QueryDTO

Inside this instance is my list

I am trying to pass some value back into the list:

aDTO .HumID = "W352936514";

and I am getting a error
Cannot implicitly convert type string to System.Collection.Generic.List<>

Please let me know what I am doing wrong.

Your field is of type List<HumDTO>
Your value is of type string

It's a little difficult to understand what you're trying to achieve. Could you tell us a little more about the HumDTO type?

Basically I have a ID number which was originally set-up as a string, But now we need the HumDTO to accept a list of IDs.

I created a class HumDTO :

[DataContract]
Public class HumDTO

{

[DataMember(IsRequired = true)]
public string HumID
{

    get;
    set;
}
}

Next I call the class above from another class which is called QueryDTO
[DataMember]
public List<HumDTO> HumaID
{

      get;
      set:
}

I created a test Case and her it is

QueryDTO qDTO = new QueryDTO();
qDTO.Accountnumber = "111111111";
qDTO .HumId = "1253647W";

Cannot implicitly convert type string to System.collection.Generic.List<>

You're treating QueryDto as if it is a single HumDto whereas in fact it has a member HumId which is itself many HumDtos.

I'm not sure what the aim is but if you wanted to get or set a HumId you need something like:
foreach(HumDto hd in QueryDto.HumId) {
hd.humid = "1234567W";
}
