Question

我是一个真正的新手，虽然我发现一个问题和答案非常相似（Winforms C# change string text order）我仍然需要一些帮助，特别是由于下面的第3点使得它有点棘手。 / p>

该字符串由3个“单词”组成，其顺序需要更改。字符串总是具有相同的模式：“WordOne WordTwo WordThree” - 一些例子是“Car Storage Sydney”，“Boat Storage Melbourne”和“Caravan Storage Brisbane”。
每个'Word'总是由一个空格分隔。据我了解，这将用于拆分变量，然后可以重新格式化以实现所需的订单更改（见下文4）
这是一个有点棘手的地方：第三个'Word'有时实际上是两个单词，即“Word 3”而不是“WordThree”或许更好地用另一个例子解释：“Boat Storage Gold Coast”< / p>
所需的订单更改是“WordThree WordOne WordTwo”（基本上，只是将“WordThree”从后面移到前面）所以使用与上面1中相同的示例，完成的结果将是“悉尼汽车存储” “，”墨尔本船存储“和”布里斯班大篷车存储“。基于有时两个措辞的“三个字”，如上面的3.所示，那个棘手的问题将是“黄金海岸船存储”

我希望我已经解释得很好。

除了上面3.中描述的问题，我认为它应该是这样的，只是我粗略的新手尝试代码：

string wordsBefore = "WordOne WordTwo WordThree";
string[] wordsWorking = wordsBefore.Split(new string[]{" "});
string wordsAfter = ("{0} {1} {2}", wordsWorking[2], wordsWorking[0], wordsWorking[1]);

我认为这非常接近？

但是，当然，由于上面3中描述的问题，需要额外的代码来检测“WordThree”何时包含两个单词并以某种方式将它们作为一个单词处理。我想你知道我的意思了！

急切等待一些帮助！

Answer 1

您可以告诉Split仅提供一定数量的结果：

string wordsBefore = "WordOne WordTwo Word Three";
string[] wordsWorking = wordsBefore.Split(new [] {' '}, 3);
string wordsAfter = string.Format("{0} {1} {2}", 
                wordsWorking[2], wordsWorking[0], wordsWorking[1]);

// result: "Word Three WordOne WordTwo"

或者如果你想聪明地使用String.Format：

string wordsBefore = "WordOne WordTwo Word Three";
string[] wordsWorking = wordsBefore.Split(new [] {' '}, 3);
string wordsAfter = string.Format("{2} {0} {1}", wordsWorking);

Answer 2

string wordsBefore = "WordOne WordTwo WordThree";
string[] wordsWorking = wordsBefore.Split();
string wordsAfter = ("{0} {1} {2}", string.Join(" ", wordsWorking.Skip(2)), wordsWorking[0], wordsWorking[1]);

Answer 3

保持简单。

string wordsBefore = "WordOne WordTwo WordThree";
string[] wordsWorking = wordsBefore.Split(new string[]{" "});
string word1 = wordsWorking[0];
string word2 = wordsWorking[1];
string word3 = wordsWorking[2];

if (wordsWorking.length == 4)
   word3 = word3 + " " + wordsWorking[3];

string wordsAfter = ("{0} {1} {2}", word3 word1, word2);

Answer 4

const string wordsBefore = "WordOne WordTwo Word Three";
string[] wordsWorking = wordsBefore.Split();
var thirdWord = wordsWorking.Skip(2).Aggregate((s, s1) => s + " " + s1);    
string wordsAfter = string.Format("{0} {1} {2}", thirdWord, wordsWorking[0], wordsWorking[1]);

Answer 5

以下是我的例子：

string text = "word one<splittag>word two and some other words<splittag>word three with   some text";
        string[] words = text.Split(new string[] { "<splittag>" }, StringSplitOptions.None);
        Label1.Text = String.Format("{2},{0},{1}", words[2], words[0], words[1]);

希望它有所帮助！
