Is it possible to extend arrays in C#?
提问by Jader Dias
I'm used to add methods to external classes like IEnumerable. But can we extend Arrays in C#?
我习惯于向 IEnumerable 等外部类添加方法。但是我们可以在 C# 中扩展数组吗？
I am planning to add a method to arrays that converts it to a IEnumerable even if it is multidimensional.
我计划向数组添加一个方法，即使它是多维的，也可以将其转换为 IEnumerable。

static class Extension
{
public static string Extend(this Array array)
{
return "Yes, you can";
}
}
class Program
{
static void Main(string[] args)
{
int[,,,] multiDimArray = new int[10,10,10,10];
Console.WriteLine(multiDimArray.Extend());
}
}

I did it!
我做到了！
public static class ArrayExtensions
{
public static IEnumerable<T> ToEnumerable<T>(this Array target)
{
foreach (var item in target)
yield return (T)item;
}
}

Yes. Either through extending the Arrayclass as already shown, or by extending a specific kind of array or even a generic array:
是的。通过扩展Array已经显示的类，或者通过扩展特定类型的数组甚至通用数组：
public static void Extension(this string[] array)
{
// Do stuff
}
// or:
public static void Extension<T>(this T[] array)
{
// Do stuff
}
The last one is not exactly equivalent to extending Array, as it wouldn't work for a multi-dimensional array, so it's a little more constrained, which could be useful, I suppose.
最后一个并不完全等同于 extends Array，因为它不适用于多维数组，所以它受到了更多的限制，我想这可能很有用。
