Update specific object in array <p>I have a DataTable and an array of objects that I loop through.</p> <p>For each row in a data table, I search through my collection of objects with Linq, and if found, that object needs to be updated. But how do I refresh my collection without reloading it from the database?</p> <pre><code>Car[] mycars = Cars.RetrieveCars(); //This is my collection of objects //Iterate through Cars and find a match using (DataTable dt = data.ExecuteDataSet(@"SELECT * FROM aTable").Tables[0]) { foreach (DataRow dr in dt.Rows) //Iterate through Data Table { var found = (from item in mycars where item.colour == dr["colour"].ToString() &amp;&amp; item.updated == false select item).First(); if (found == null) //Do something else { found.updated = true; Cars.SaveCar(found); //HERE: Now here I would like to refresh my collection (mycars) so that the LINQ searches on updated data. //Something like mycars[found].updated = true //But obviously mycars can only accept int, and preferably I do not want to reload from the database for performance reasons. } </code></pre> <p>How else can I search and update a single item in the array?</p>
