I have two string arrays (str and str1):
string[] str = new string[] { "Sun", "Mon", "Tues", "Wed", "Thur", "Fri", "Sat" };
string[] str1 = new string[] { "Mon", "Tues", "Wed" };
string[] str2 = new string[10];
I want to create a new array which will contain the items that appears only in one of the arrays. The output will be:
str2[]={"Sun","Thur","Fri","Sat"}
You can use Enumerable.Except, it produces the set difference of two sequences by using the default equality comparer to compare values.
var str2= str.Except(str1);
NOTE: Don't forget to add System.Linq namespace like;
using System.Linq;
System.Linq. See Soner Gönül has provided working demoYou can use Enumerable.Except method with LINQ. Don't forget to add System.Linq namespace. like;
Produces the set difference of two sequences by using the default equality comparer to compare values.
string[] str = new string[] { "Sun", "Mon", "Tues", "Wed", "Thur", "Fri", "Sat" };
string[] str1 = new string[] { "Mon", "Tues", "Wed" };
var str2 = str.Except(str1);
foreach (var i in str2)
{
Console.WriteLine(i);
}
Output will be;
Sun
Thur
Fri
Sat
Here a demonstration.
string[] str = new string[] { "Sun", "Mon", "Tues", "Wed", "Thur", "Fri", "Sat" };
string[] str1 = new string[] { "Mon", "Tues", "Wed" };
var str2 = str.Where(t => !str1.Contains(t)).ToArray();
Also you can use Where with Contains
var str2 = str.Where(s => !(str1.Contains(s)).Select(s => s);
