Add Multiple values to ComboBox

Is there a shorter way to add all the numbers from 1-100 into a combobox in c#? Currently the method i am aware of is to add 1 by 1 manually and that consumes time. Is there a faster way to do it?

P.S I am very new to c#, so if you could kindly explain your code to me that would be very helpful. :D

This question has already been answered by Alfie Goodacre and is an efficient way to add multiple items to a combobox with little code, but for people new to c# or programming in general, the simplest way to add numerous numbers to a combobox would be a single for loop as follows, wouldn't it?

for (int i = 1; i <= 100; i++)
{
    comboBox1.Items.Add(i);
}

The integer variable "i" starts at 1 and increments by one. As long as it's lower or equal to 100, its value will be added as an item to the combobox.

Firstly you should create an array containing 1-100. This can be done like so

int[] list = Enumerable.Range(1, 100).Cast<object>().ToArray();

After this you need to add them all at once with AddRange()

comboBox1.Items.AddRange(list);

This code will add 1-100 to your comboBox

To use this code you need using System.Linq; at the top of your document

EDIT: Thanks to @Badiparmagi for correcting me on adding the values to the comboBox
