Question

我在c＃中有一个字符串。我想将该字符串拆分为2个字符串集，如：

string str = "Split handles splitting upon string and character delimiters."

输出应为：

1: "Split handles"
2: "splitting upon"
3: "string and"
4: "character delimiters."

这样做的最佳方法是什么？

以下是我的尝试：

    private List<string> Spilt(string text)
    {
        List<string> bunch = new List<string>();
        int block = 15;
        string[] words = text.Split(' ');
        int length = words.Length;
        int remain = 0;

        while(remain < length)
        {
            bunch.Add(string.Join(" ", words.Take(block)));
            remain += block;
        }

        return bunch;
    }

Answer 1

最简单的方法是在每个空间拆分，然后重新加入＆＃34;对回来，像这样：

var pairs = str.Split(' ')
    .Select((s,i) => new {s, i})
    .GroupBy(n => n.i / 2)
    .Select(g => string.Join(" ", g.Select(p=>p.s)))
    .ToList();

试试这个

        string str = "Split handles splitting upon string and character delimiters.";
        var strnew = str.Split(' ');
        var strRes = string.Empty;
        int j = 1; 
        for (int i = 0; i < strnew.Length; i=i+2)
        {
            strRes += j.ToString()+": " + @"""" + strnew[i] + " " + strnew[i+1] + @"""" +"\n" ;
            j++; 
        }
        Console.Write(strRes); 
        // print strRes
