<h2 id="x10d">X10D</h2>
|
|
|
|
<p>X10D (pronounced <em>extend</em>), is a .NET package that provides extension methods for numerous types. The purpose of this library is to simplify a codebase by reducing the need for repeated code when performing common operations. Simplify your codebase. Take advantage of .NET. Use extension methods.</p>
|
|
<p><em>(I'm also <a href="https://www.pcmag.com/encyclopedia/term/dogfooding">dogfooding</a> this library, so there's that.)</em></p>
|
|
<h3 id="what-are-extension-methods">What are extension methods?</h3>
|
|
<p>Extension methods are a clever .NET feature that augment existing types with new functionality. They are defined as
|
|
static methods in a static class, and are called as if they were instance methods on the type they are extending. Take,
|
|
for example, the following code:</p>
|
|
<pre><code class="lang-csharp">public static class Program
|
|
{
|
|
public static void Main()
|
|
{
|
|
string str = "Hello, world!";
|
|
Console.WriteLine(str.Reverse());
|
|
}
|
|
}
|
|
|
|
public static class StringExtensions
|
|
{
|
|
public static string Reverse(this string str)
|
|
{
|
|
char[] chars = str.ToCharArray();
|
|
Array.Reverse(chars);
|
|
return new string(chars);
|
|
}
|
|
}
|
|
</code></pre>
|
|
<p>This will print <code>!dlrow ,olleH</code> to the console. The <code>Reverse</code> method is defined in the <code>StringExtensions</code> class, yet is
|
|
called as if it were an instance method on the <code>str</code> variable, even though it's not.</p>
|
|
<h3 id="why-use-extension-methods">Why use extension methods?</h3>
|
|
<p>Extension methods were introduced when LINQ was added to .NET. LINQ is a set of extension methods that provide a way to
|
|
query, filter, and transform data. If you were to access LINQ's methods statically, you would have to write code like
|
|
this:</p>
|
|
<pre><code class="lang-csharp">public static class Program
|
|
{
|
|
public static void Main()
|
|
{
|
|
int[] numbers = { 1, 2, 3, 4, 5 };
|
|
IEnumerable<int> evenNumbers = Enumerable.Where(numbers, x => x % 2 == 0);
|
|
IEnumerable<int> doubledNumbers = Enumerable.Select(evenNumbers, x => x * 2);
|
|
int sum = Enumerable.Sum(doubledNumbers);
|
|
Console.WriteLine(sum);
|
|
}
|
|
}
|
|
</code></pre>
|
|
<p>And if you wanted to one-line this, you'd have to write this:</p>
|
|
<pre><code class="lang-csharp">public static class Program
|
|
{
|
|
public static void Main()
|
|
{
|
|
int[] numbers = { 1, 2, 3, 4, 5 };
|
|
Console.WriteLine(Enumerable.Sum(Enumerable.Select(Enumerable.Where(numbers, x => x % 2 == 0), x => x * 2)));
|
|
}
|
|
}
|
|
</code></pre>
|
|
<p>This is a lot of code to write, and it's not very readable. The nested method calls make it incredibly difficult to
|
|
follow. However, because LINQ is implemented as extension methods, you can write the following code instead:</p>
|
|
<pre><code class="lang-csharp">public static class Program
|
|
{
|
|
public static void Main()
|
|
{
|
|
int[] numbers = { 1, 2, 3, 4, 5 };
|
|
Console.WriteLine(numbers.Where(x => x % 2 == 0).Select(x => x * 2).Sum());
|
|
}
|
|
}
|
|
</code></pre>
|
|
<p>Because the methods are called as if they were instance methods on <code>IEnumerable<T></code>, they can be chained together,
|
|
making the code much more readable.</p>
|
|
<p>X10D aims to provide these same benefits as LINQ, but for dozens of other types and for countless other use cases.</p>
