Initialize var to null

Question

I have seen how to initialize var to null. This does not help in my situation. I have

string nuller = null;
var firstModel = nuller;
if(contextSelectResult.Count() > 0)
    firstModel = contextSelectResult.First();

I get error

Cannot implicitly convert type 'SomeNamespace.Model.tableName' to 'string'.

I am trying to avoid try/catching InvalidOperation for First() when no first exists as its expensive. So, how can I get past the scope issue here?

Answer 1

You can try this:

var firstModel=(dynamic) null; 

Answer 2

You can use FirstOrDefault() instead.

firstModel = contextSelectResult.FirstOrDefault();

if(firstModel != null)
{
   ...
}
