I want to return a string of matches found in the array1
public static string[] FindMatchs(string[] array1, string[] array2) {
return array1.Where(x => array2.Contains(x)).ToArray();
}
input:
var a1 = new string[] { "ca", "tr", "stack" };
var a2 = new string[] { "car", "house", "tree", "stackoverflow", "bus" };
the method should return "ca", "tr", "stack"
I made a mistake in my previous code. Please see below for a working example.
You want to use a combination of .Contains() and .Any() to achieve what you are looking for.
Here is a code example based on your code, that should work (names in signature has been changed for clarity):
public static string[] FindMatchs(string[] array, string[] filter) {
return array.Where(x => filter.Any(y => x.Contains(y))).ToArray();
}
Here is a live example of it: https://dotnetfiddle.net/HdB79V
You are almost there.. a slight change to the line in you method.
return array1.Where(x => array2.Any(y=>y.Contains(x))).ToArray();
The following example returns matches in two lists:
public class names
{
public int ID {get;set;}
public string Name {get;set;}
}
List<names> l1 = new List<names>();
List<names> l2 = new List<names>();
Populate both list:
for example
Name xyz = new Name()
xyz.id = 1;
xyz.name = "blah";
l1.Add(xyz)
var matches = (from l1 in list1
join l2 in list2 on l1.Name equals l2.Name
select sp).ToList();
OR if you want to use Arrays only
var list1 = new string[] {"xyz", "abc"};
var list2 = new string[] {"abc"};
var matches = list1.Intersect(list2);
foreach (string s in matches)
{
//s will return common
}
