如何使用C＃比较两个RichTextBox文本 [英] How to compare two richtextbox text using C#

问题描述

我编写了一个逻辑来比较两个ricttext框的内容，但是输出差异文本未在预期索引处突出显示。它比预期的索引早开始。

I have written a logic to compare two ricttext boxes content, but the output difference text is not highlighted at the expected index. It starts ahead of the expected index. I have given below the logic i have used.

private void CompareRichTextContents(RichTextBox target, RichTextBox dest)
    {
        string[] targetLines = target.Lines;
        string[] destLine = dest.Lines;
        List<string> result=targetLines.Except(destLine).ToList<string>();
        foreach (string str in result)
        {

            int lineIndex=Array.IndexOf(targetLines, str);
            int lineCount=0;
            for (int index = 0; index < lineIndex; index++)
            {
                lineCount+=targetLines[index].Length;
            }
            target.SelectionBackColor = Color.Yellow;
            target.SelectionColor = Color.Black;
            target.SelectionStart = lineCount;
            target.SelectionLength = str.Length;

        }
    }
