WPF 文本溢出

Question

我目前正在尝试这样做，以便当我接受一个字符串时，它会填满第一个文本块，直到它溢出，然后它应该从文本块 2 开始。目前，我将它的字符串切成两段最后一个单词的最后一个结尾，我猜是可以放入文本块 1 的最大字符数，后半部分是 2，但我遇到的问题是永远不可能弄清楚在哪里切断文本，因为当它换行时，剩下的空间会占用不同的大小。所以我只剩下 textblock 1 在末尾有一些被截断的文本，这使得两者之间似乎缺少一些单词。有没有办法以编程方式找到文本块上的溢出？

ps- 文本块是在运行时在 C# 中创建的，而不是 wpf 标记。

这就是我所做的。我使用 myDescription 并尝试根据我近似的大小将其放入 myDesc[0] 和 [2] 中。问题是，如果我猜测大小阈值太大，它会给 myDesc[0] 留下一个 ... 或截断的词，如果我把它估计得太小，它就会有巨大的尴尬差距。我切断的任何数字都没有。

TextBlock[] myDesc = new TextBlock[2];
string myDescription = infoLoader.games[gameID].description[currentLanguage];
        string[] myWords = myDescription.Split(' ');

        string firstPart = "";
        string secondPart = "";


        int currentWord = 0;


        // New and improved way
        int currentLine = 0;
        int charsInLine = 0;
        while (currentWord < myWords.Length)
        {
            // Determine the size of the word based on the number of characters and size of certain characters in it.
            int myWLength = myWords[currentWord].Length;
            int iCount = 0;
            for (int i = 0; i < myWords[currentWord].Length; i++)
            {
                if (myWords[currentWord][i] == 'm' || myWords[currentWord][i] == 'M')
                {
                    Console.Write("M or m. ");
                    myWLength++;
                }
                else if (myWords[currentWord][i] == 'i' || myWords[currentWord][i] == 'l' || myWords[currentWord][i] == 'I' || myWords[currentWord][i] == 'j' || myWords[currentWord][i] == 'í' || myWords[currentWord][i] == 't')
                {
                    iCount++;
                }
            }
            iCount = (iCount / 2);
            myWLength -= iCount;
            if (myWords[currentWord] == "SKIP")
            {

查看与 TextBlock 关联的TextWrapping属性，或许可以使您的代码更简单。

<StackPanel>
  <TextBlock Text="One line of text"/>
  <TextBlock Width="50" TextWrapping="WrapWithOverflow" Text="One line of text"/>
  <TextBlock Width="50" TextWrapping="Wrap" Text="One line of text"/>
</StackPanel>
