How to query on an Entity attribute key only when it's of type KeyValuePair ? RRS feed

    Hi,
    I have an entity contact with an attribute of type "KeyValuePair", the key name is "degree" and the value depends from one contact to another.

    I need to set the value of the degree of each contact, so I want to basically write something like this :

    contact.Attributes["degree"].Value=123;

    But this statement isn't accepted, it says that the attributes is expecting a KeyValuePair type not just a key, but I can't do that because that's what i want to set.

    Can you please help ?
    Thanks

    Hi,
    there is no such an attribute type as "KeyValuePair" for crm entities, please check the attribute definition inside your entity.
    If for example is a whole number, just set in this way:

    contact["new_degree"] = 123;

    and pay attention also to the logicalname (if is a custom attribute it will contain the prefix)

    Hi Guido, Thank you for your reply.

    I tried what you just wrote but it said : "Cannot apply indexing with [] to an expression of type Entity"


    EDIT:

    That's the rest of this part in my code:

     foreach (var contact in result.Entities)
                    {
                        var studentdegree = contact["degree"];

                          ............
                      }

    Hi _Vikram,
    I've been trying to do this:
     foreach (var contact in result.Entities)
                    {
                        var studentdegree = contact.Attributes["degree"];
                         .........
                    }

    also I've tried : contact.Attributes["degree"].Value;

    but this is the error i receive :
