Convert Linq Query Result to Dictionary

Try using the ToDictionary method like so:

var dict = TableObj.Select( t => new { t.Key, t.TimeStamp } )
                   .ToDictionary( t => t.Key, t => t.TimeStamp );

Looking at your example, I think this is what you want:

var dict = TableObj.ToDictionary(t => t.Key, t=> t.TimeStamp);

Try the following

Dictionary<int, DateTime> existingItems = 
    (from ObjType ot in TableObj).ToDictionary(x => x.Key);

Or the fully fledged type inferenced version

var existingItems = TableObj.ToDictionary(x => x.Key);
