Hello Please some help me with a code or algorithm to do this effectively.
I have two arrays ArrayA and ArrayB. I would love to search for A in B to return the result below

ARRAY A:

{“JACK|MATTER|15|Montgomery|40037228”
,“RICHARD|MATTER|35|ROWTOWN|40037228”
,“BECK|SPENCER|25|HuggesTown|40037228”
,“DAVID|MARY|28|HELLSPOT|5637829222”}

ARRAY B:

{“MATTER|JACK|Montgomery”,
“RICHARD|BOXER|ROWTOWN”,
“DAVID|MARY|HELLSPOT”}

RESULT:
{“DAVID|MARY|28|HELLSPOT|5637829222”,
“JACK|MATTER|15|Montgomery|40037228”}

Hi,

How about the following?

image

arrResult = arrA.Where(Function(s1) arrB.Any(Function(s2) s2.Split("|"c).All(Function(ss) s1.Split("|"c).Contains(ss)))).ToArray()

Hello Thanks @Yoichi for always coming to the rescue. It works fine , but wanted to add if I had this JACK|MATTER|15|Montgomery Site|40037228 as an element in arrA ,how do I make it still select this?
its not exactly Montgomery but then it has something like it

I modified it to this is this okay ?

arrA.Where(Function(s1) arrB.Any(Function(s2) s2.Split("|"c).All(Function(ss) s1.Contains(ss)))).ToArray()

Hi,

It should be as the following, for example.

arrA.Where(Function(s1) arrB.Any(Function(s2) s2.Split("|"c).All(Function(ss2) s1.Split("|"c).Any(Function(ss1) ss1.Contains(ss2))))).ToArray()

Evaluate them using Srting.Contains method.

OR

arrA.Where(Function(s1) arrB.Any(Function(s2) s2.Split("|"c).All(Function(ss2) s1.Split("|"c).Any(Function(ss1) ss1.StartsWith(ss2))))).ToArray()

Evaluate them using Srting.StartsWith method.

Please note that there is possibility to match unintended string.

Regards,
