Question

我有一个长字符串，想要在预定义的字数统计后在新行中断开该字符串。

我的字符串如下：

字符串是编程中使用的数据类型，例如整数和浮点单元，但用于表示文本而不是数字。它由一组字符组成，这些字符也可以包含空格和数字。

我希望在50个字符之后将此字符串拆分为新行。

Answer 1

string text = "A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers.";

int startFrom = 50;
var index = text.Skip(startFrom)
                .Select((c, i) => new { Symbol = c, Index = i + startFrom })
                .Where(c => c.Symbol == ' ')
                .Select(c => c.Index)
                .FirstOrDefault();


if (index > 0)
{
    text = text.Remove(index, 1)
        .Insert(index, Environment.NewLine);
}

Answer 2

琐碎的是，您可以轻松地在 50个字符之后完成拆分，为此简单：

    string s = "A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers.";
    List<string> strings = new List<string>();
    int len = 50;
    for (int i = 0; i < s.Length; i += 50)
    {
        if (i + 50 > s.Length)
        {
            len = s.Length - i;
        }
        strings.Add(s.Substring(i,len));
    }

您的结果保存在strings。

Answer 3

        string thestring = "A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. It is comprised of a set of characters that can also contain spaces and numbers.";
        string sSplitted = string.Empty; 
        while (thestring.Length > 50)
        {
            sSplitted += thestring.Substring(1, 50) + "\n";
            thestring = thestring.Substring(50, (thestring.Length-1) -50);
        }
        sSplitted += thestring;
