C# remove a full string from an array based on a substring [duplicate]

Question

Say I have an array of strings

string[] my_array = { "XY:1234567;ZW:124", "XY:124252"};

And a user inputs string user_input = "1234567";

how can I remove the entire string from my_array

so after remove XY:1234567;ZQ:124 is removed based on the partial input

my_array = { "XY:124252" };

My first attempt:

string[] my_array = { "XY:12345678;ZW:124", "XY:124252" };
string user_input = "1234567";
if(my_array.Contains(user_input))
    Console.WriteLine("Inside");
else
    Console.WriteLine("Not Inside");

Outputted Not Inside

My second attempt:

string[] my_array = { "XY:12345678;ZW:124", "XY:124252" };
string user_input = "%1234567%"; // Tried % to do a partial string I think?
if(my_array.Contains(user_input))
    Console.WriteLine("Inside");
else
    Console.WriteLine("Not Inside");

Outputted Not Inside

Im out of ideas

array.Contains checks if the array contains the entire string. You want array.Any(s => s.Contains(...)). — CodeCaster

you need String.Contains(). Try like:

string[] my_array = { "XY:12345678;ZW:124", "XY:124252" };
string user_input = "1234567";
foreach( var item in my_array)
{
   if(item.Contains(user_input))
      Console.WriteLine("Inside");
   else
      Console.WriteLine("Not Inside");
}
