如何从C#数组中删除重复项? [英] How do I remove duplicates from a C# array?

问题描述

我一直在使用C#中的string[]数组，该数组从函数调用中返回.我可以转换为Generic集合，但我想知道是否有更好的方法可以做到这一点，可能是通过使用临时数组.

I have been working with a string[] array in C# that gets returned from a function call. I could possibly cast to a Generic collection, but I was wondering if there was a better way to do it, possibly by using a temp array.

从C#数组中删除重复项的最佳方法是什么?

推荐答案

您可以使用LINQ查询来做到这一点:

int[] s = { 1, 2, 3, 3, 4};
int[] q = s.Distinct().ToArray();
