此代码是NBuilder的一部分。我今天过得很糟糕......为了证明这一点，我不明白这个（简单）代码试图做什么。

这是答案，后面是代码。

GetRandom.Phrase(5) == null or et or ut or do or elit or amet.. 
                       (nothing over 4 characters)
GetRandom.Phrase(4) == null or sit or sed or do .. 
                       (nothing over 3 characters)
GetRandom.Phrase(3) == null or et or ut or do  (nothing over 2 characters)
GetRandom.Phrase(2) == null 
GetRandom.Phrase(1) == null

和代码...

private static readonly string[] latinWords = { "lorem", "ipsum", "dolor", 
    "sit", "amet", "consectetur", "adipisicing", "elit", "sed", "do",
    "eiusmod", "tempor", "incididunt", "ut", "labore", "et", "dolore",
    "magna", "aliqua" };

public virtual string Phrase(int length)
{
    var count = latinWords.Length;
    var result = string.Empty;
    var done = false;
    while (!done)
    {
        var word = latinWords[Next(0, count - 1)];
        if (result.Length + word.Length + 1 > length)
        {
            done = true;
        }
        else
        {
            result += word + " ";
        }
    }
    return result.Trim();
}

我会认为该方法应该返回 x 个短语或至少指定长度的随机短语？

该代码返回一个小于或等于指定长度的随机短语（以字符为单位）。关键是这一行：

if (result.Length + word.Length + 1 > length)

这保证了结果的字符长度（包括新添加的单词）不超过length.
