c# - 如何拆分字符串并删除每个第 n 个元素？

Question

我正在做这样的事情

public string[] getArray() {

    string text = "1 ab cd 2 ef gh 3 ij kl 4 mn";
    string[] arr = text.Split(" ").remove(every third element); //remove the 1,2,3,4 etc

    return arr;
}

Answer 1

您可以 use Linq to skip every nth element .

public string[] getArray() {

    string text = "1 ab cd 2 ef gh 3 ij kl 4 mn";
    string[] arr = text.Split(" ").Where((x, i) => i % 3 != 0).ToArray();
    return arr;
}
