C-Sharp Filter Example - Filter - Sample Code

Description: Illustrates the C# Syntax for Filter.

Example Class Main:

using System;
public class clsFilter
{
 
    public void Main()
    {
 
 
        //****************************************************************************************
        // Purpose: Returns a zero-based array containing a subset of a String array based on
        // specified filter criteria.
        //
        // Syntax: 	Filter (Source As String(), Match As String, Include As Boolean, _
        // Compare As CompareMethod) As String()
        //
        // Source - Required - one-dimensional string array to be searched
        // Match - required - string to search for
        // Include - optional - Boolean value indicating whether to return substrings that 
        // include or exclude Match.
        // Compare - optional - numeric value indicating compare method - CompareMethod.Binary
        // or CompareMethod.Text
        //****************************************************************************************
 
        Console.WriteLine("Example #1: 	Filter(Source, Match, Include,Compare) As String");
        string[] myStrings = new string[4];
        myStrings[0] = "This";
        myStrings[1] = "is";
        myStrings[2] = "my";
        myStrings[3] = "string";
 
        string[] FilteredStrings = null;
        FilteredStrings = Microsoft.VisualBasic.Strings.Filter(myStrings, "is", true, Microsoft.VisualBasic.CompareMethod.Text);
 
        foreach (string myItem in FilteredStrings)
        {
            Console.WriteLine(myItem); // Returns ["This", "Is"].
        }
 
 
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
 
 
        //Prevent console from closing before you press enter
        Console.ReadLine();
 
    }
 
 
}

Example Class Program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace CSharp_Syntax
{
    class Program
    {
        static void Main(string[] args)
        {
 
 
            clsFilter myFilter = new clsFilter();
            myFilter.Main();
 
        }
    }
