C# Array.Find search

Question

I want to search from the array. This is my code

string[] Main_Events = { "Five Ships In The Harbour", "Australia Day", "Christmas", "New Years", "The Melbourne Cup", "Australian Open Tennis" };
string search_str = "Australia Day";

string value1 = Array.Find(Main_Events, element => element.Contains(search_str));

The search works fine if i search Australia Day but if the search is The Australia Day. The value of value1 is null.

How can i search if the search value is The Australia Day and in the array the value is Australia Day then the value of value1 should be Australia Day or true.

I am using Array.Find because i want to search from 5 different arrays. Like Main_Events, i have four other arrays.

Thanks in advance

For custom search you have to create your own extension search method. I think you know why it is returning null on The Australia Day. — Waqar Ahmed

ok so do you mean i should use foreach to compare the values but i was using this because i have to search through 5 different arrays and then writing 5 foreach loops to search will increase the code thats why i use array.find — Owais Ahmed

Try to search element in search_str:

string value1 = Array.Find(Main_Events, element => element.Contains(search_str) || search_str.Contains(element));

Its not a generic solution. Suppose he have Football Cup and Tennis Cup. Guess what happens when you try to find 'Cup'. Also its depends on the requirement and input though :)

in such a case just use FindAll the solution will work fine . var value1 = Array.FindAll(Main_Events, element => element.Contains(search_str) || search_str.Contains(element));

@WaqarAhmed yes, it depends, but it may be an option

If you need the array node value to be equal to or a substring of the given string then you can change the search to below:

var value1 = Array.Find(mainEvents, element => searchStr.Contains(element));

You can change accordingly for case insensitive comparison(by converting to uppercase).

string[] Main_Events = { "Five Ships In The Harbour", "Australia Day", "Christmas", "New Years", "The Melbourne Cup", "Australian Open Tennis" };
string search_str = "The Australia Day";

List<string> search_strs = search_str.Split(null).Where(s => s != string.Empty).ToList();
if (search_strs.Count > 0)
{                  
    List<string> searchResult = Main_Events.Where(x => search_strs.Any(keyword => (x).Contains(keyword))).ToList();                                                                   
}
