富文本框中的WPF。在框中查找或選擇文本？

Question

編輯：包括在後

我想提出一個一擲千金的遊戲，我所擁有的一切，除了消除對雙方的數字，因爲他們猜測工作的結束了我的整個程序代碼。希望有人能指導我...

Here is what my GUI looks like

GUI after first round. Box 1 is "my" box, bolded boxes are ones I've already opened

我有一個WPF在這2個富文本框。我有一組數字，我把一半放在一個文本框中，一半放在另一個文本框中。我將這些值顯示爲適合遊戲主題的貨幣。

這是我對陣列碼，並顯示在文本框中：

//initialize array with dollar values 
     displayNumbers = new int[] {0, 1, 5, 10, 25, 50, 75, 100, 200, 300, 400, 500, 750, 
      1000, 5000, 10000, 25000, 50000, 75000, 100000, 200000, 300000, 400000, 500000, 750000, 1000000}; 

     //initialize usedNumbers array with a length 
     usedNumbers = new int[displayNumbers.Length]; 

     //display amounts in 1st textblock. boxSize = 26 (size of array) 
     for(int i = 0; i<(boxSize/2); i++) 
     { 
      textBox1.AppendText(displayNumbers[i].ToString("C0") + " \n"); 
     } 

     //display amounts in 2nd textblock 
     for(int i = boxSize/2; i < boxSize; i++) 
     { 
      textBox2.AppendText(displayNumbers[i].ToString("C0") + "\n"); 
     } 

我的遊戲目前的工作方式是，該陣列洗牌無論你按下一步的按鈕，該值將是下一個隨機數值在數組中。在我洗牌之前，我會在側面顯示數值。

如何獲取我在數組中的索引的當前值，然後在我的富文本框中查找該數字，然後更改顏色或背景等，以便用戶知道該值不在板上？

我已經在使用按鈕的內容來顯示與該按鈕相關的值，但我也應該從側邊框中消除該值。

從我在網上找到的，我認爲指針可能是我的答案？但我不知道如何使用這些...

我還是一個初學者，所以如果這可以用初學者的條件回答，我真的很感激它。

Answer 1

對您的問題的回答需要多個代碼塊。既然你沒有展示太多的部分，我只是引導你完成任務的建議和參考。

1. 您不需要跟蹤指數，因爲按鈕有你需要的RichTextBox和處理搜索量，即文本。

2. 從文本框中刪除所選數量。

   a。點擊按鈕後，首先在富文本框中搜索數量"$" + searchAmount + " \n"。請參閱link1或link2的解決方案。一個接一個地搜索文本框。如果在第一個發現不需要在第二個文本框中的seacrh。

   b。選擇搜索量並裝飾它。

   c。我的建議是用StrikeThrough裝飾它，而不是從文本框中刪除它。你也可以用紅色來突出顯示。刪除選定的文本很簡單，使用textBox1.SelectedText = "";。紅色突出顯示可以使用textBox1.SelectionColor = Color.Red;完成。對於刪除線，您必須使用TextRange和TextDecorationCollection。請參閱link3。
