This article mainly introduces how LINQ traverses multiple arrays, which has certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let Xiaobian take you to understand it together.

LINQ iterates over multiple arrays in a loop

A friend asked me a C#question: Is there any way LINQ can traverse multiple arrays in a loop? His code goes something like this:

foreach (var x in array1) { DoSomething(x); } foreach (var x in array2) { DoSomething(x); }

In this case, the loop body would be large, and he didn't want this repetitive code. However, he doesn't want to create an array that holds all the elements of array1 and array2. LINQ offers an elegant solution: the Concat operation. We can rewrite the above code using a single loop, as follows:

foreach (var x in array1.Concat(array2)) { DoSomething(x); }

Note that since LINQ operates at the enumerator level, it does not generate new arrays to hold the elements of array1 and array2. So, in addition to being elegant, it's efficient.

Thank you for reading this article carefully. I hope that the article "LINQ how to traverse multiple arrays" shared by Xiaobian will be helpful to everyone. At the same time, I hope that everyone will support it more, pay attention to the industry information channel, and more relevant knowledge is waiting for you to learn!
