Example: Use a single generic method that takes an IList<T> input parameter and iterate through both a list of integers and an array of string.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication2
{public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{string[] str = { "0", "1", "2", "3", "4" };
List<int> intL = new List<int>();
for (int x = 0; x < 5; x++)
{
intL.Add(x);
}
ProcessList<string>(str);
ProcessList<int>(intL);
}
static void ProcessList<T>
{
foreach (T item in coll)
{
MessageBox.Show(item.ToString());
}
}
}
}
