25 cze 2024 · In C#, appending or concatenating enumerables is a common operation when working with collections. There are several approaches to achieve this, each with its advantages and use cases. In this post, we will explore different methods to append enumerables in C# with code examples.
25 cze 2024 · One of the simplest ways to append two IEnumerable collections is by using the Concat method provided by LINQ. This method concatenates two sequences and returns a new sequence containing elements from both input sequences.
The following example demonstrates how to implement the IEnumerable<T> interface and how to use that implementation to create a LINQ query. When you implement IEnumerable<T>, you must also implement IEnumerator<T> or, for C# only, you can use the yield keyword.

Here's a simple example: IEnumerable<int> numbers = new List<int> { 1, 2, 3 }; List<int> numbersList = numbers.ToList(); numbersList.Add(4); 2. Concatenate Two IEnumerables
