c# first item i list

var first_item = list.First();

c# select first value from list

lstComp.First();
//You can also use FirstOrDefault() just in case lstComp does not contain any items.

//To get the Component Value:
var firstElement = lstComp.First().ComponentValue("Dep");

//This would assume there is an element in lstComp. An alternative and safer way would be...
var firstOrDefault = lstComp.FirstOrDefault();
if (firstOrDefault != null) 
{
    var firstComponentValue = firstOrDefault.ComponentValue("Dep");
}
