How to select exact string from List?-CodePudding

I have Json List

    {
        country: "INDIA      "
        },
 {
        country: "INDIA      "
        },
        {
        country: "INDIANA    "
        },
        {
    country: "AFRICA      "
        }

I am filtering country from the List which I have

var flights = new List<allflights>();
flights = flights.Where(x => x.Country.Contains(selectedvalue)).ToList();

In the above case if I select INDIA, INDIANA is also added to the List. But I want to pick only exact country which I am selecting. Need all the INDIA items to be added to the list. Don't want any other items to be added.

CodePudding user response：

You can modify your linq expression like below

flights.Where(x => x.Country.Equals(selectedvalue)).ToList();

Note: You can add additional code to trim the strings to fine tune per your needs

CodePudding user response：

you have to trim strings before comparing and use == instead of contains

var selectedvalue="INDIA";

List<allflights> selectedFlights = allFlights
.Where(a=> a.Country.Trim() == selectedvalue.Trim())
.ToList();

I can't see your data, so maybe you will need to use

a.Country.Trim().ToLower() == selectedvalue.Trim().ToLower())
