How Can I Efficiently Remove Elements from a Regular Array in C#?

The removal skills of the element of ordinary array elements

It is not easy to remove elements from the array containing specific objects (such as FOO objects). This article will explore two different methods to achieve this operation efficiently.

Removeat () method of using the list object

Although the ordinary array of C#does not have a built -in Removeat () method, we can cleverly use the List object to achieve it. After converting the array to list, you can use the Removeat () method to remove the element. After that, the modified List is converted back to the array to complete the element removal operation.

Custom expansion method

Another method is to create a custom extension method to simulate the behavior of the Removeat () method on the ordinary array. This method allows direct operations to operate the array without intermediate conversion. The code provided in the article is an unprepared implementation, which can be used as the starting point for your own realization. Application expansion method

After the definition of custom extension, it can be easily applied to ordinary arrays. Just call the extension method on the array and specify the index to remove the element. This operation will return a new array that does not include the element.
