我用来读取2个richtextbox内容的代码如下:

richTextBox1.Text = File.ReadAllText(tfsVersionFilePath);
richTextBox2.Text = File.ReadAllText(dbVersionFilePath);

现在,我需要比较两个富文本框内容,并突出显示两个richtextbox中更改的字符.目的是as in TFS通过c#应用程序获得差异并突出显示字符(比较文件).谢谢.

编辑:

int length = (richTextBox1.Text.Length > richTextBox2.Text.Length) ? richTextBox1.Text.Length : richTextBox2.Text.Length;
for (int i = 0; i < length; i++)
{ 
   if (richTextBox1.Text[i] != richTextBox2.Text[i])
   {
      /* and then start your highlight selection here, 
      this is where some difference between the two rich 
      text boxes begins */

      richTextBox1.Select(i, 1); 
      richTextBox1.SelectionColor = System.Drawing.Color.Yellow; 
      richTextBox1.SelectionBackColor = System.Drawing.Color.Red;
   }
}

我从调试中理解的是,在执行特定行之后,指向文本光标的richTextBox1 Select或SelectionColor或SelectionBackColor方法增加到7个位置.如何保持 richTextBox1 …
