update value in list c# code example

Example 1: find a value in list of objects in c#

var item = TextPool.FirstOrDefault(o => o.Name == "test");
if (item != null)
       item.value = "Value";

Example 2: how to add a value to a list in python

myList = [apples, grapes]
fruit = input()#this takes user input on what they want to add to the list
myList.append(fruit)
#myList is now [apples, grapes, and whatever the user put for their input]

Example 3: 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");
}

Example 4: update values in array in php

//With Keys
$array['key3'] = 'new value';
//Without Knowing Keys
$array[2] = 'new value';
