C# List Remove By Index

When working with lists in C#, you may need to remove an item from the list by its index. This can be accomplished easily using the List<T>.RemoveAt method.

Syntax

public void RemoveAt(int index);

The RemoveAt method takes the index of the item to be removed as input.

Example

Here's an example of how to use the RemoveAt method:

List<string> fruits = new List<string>();
fruits.Add("apple");
fruits.Add("banana");
fruits.Add("orange");
Console.WriteLine("Before removal:");
foreach (string fruit in fruits)
{
    Console.WriteLine(fruit);
}

fruits.RemoveAt(1);

Console.WriteLine("After removal:");
foreach (string fruit in fruits)
{
    Console.WriteLine(fruit);
}

In this example, we create a list of fruits and add three items to it. We then print out the list before removing an item at index 1 (the second item). Finally, we print out the list again to show that the item has been removed.

Conclusion

The List<T>.RemoveAt method is a useful tool when working with lists in C#. It allows you to remove an item from the list by its index, which can be helpful when you need to reorder or modify the list.
