C# - Usinq Linq to select items that is in a semi-comma separated string?

To select items from a collection based on whether they are present in a semi-colon separated string using LINQ in C#, you can follow these steps:

  1. Split the semi-colon separated string into an array of items.
  2. Use LINQ's Where method to filter the collection based on whether each item exists in the array.

Here's an example:

using System; using System.Linq; class Program { static void Main() { // Sample semi-colon separated string string semiColonSeparatedString = "apple;banana;orange;grape"; // Sample collection of items string[] items = { "apple", "banana", "cherry", "grape" }; // Split the semi-colon separated string into an array of items string[] stringItems = semiColonSeparatedString.Split(';'); // Use LINQ to select items from the collection that are in the semi-colon separated string var selectedItems = items.Where(item => stringItems.Contains(item)); // Output the selected items Console.WriteLine("Selected Items:"); foreach (var item in selectedItems) { Console.WriteLine(item); } } }

In this example, the output will be:

Selected Items: apple banana grape

This demonstrates how you can use LINQ to select items from a collection based on whether they exist in a semi-colon separated string.
