我有一个RichTextBox,我想在text的middle中使用add some text. 例如,我得到了这段文字:
I have a RichTextBox and I want to add some text in the middle of the text. For example I got this text:
"FirstText SecondText"
"FirstText SecondText"
我想在"FirstText" and the "SecondText".之间添加一些文本 我试图split the text to 2 strings并在第一个文本中添加我的多余文本,然后在第二个字符串中添加他.它起作用了,但是却破坏了我的richTextBox1.SelectionColor (I got color...). 那么如何在不剪切richTextBox1.Text的情况下添加文本,或者如何保存所有颜色数据?
I want to add some text between the "FirstText" and the "SecondText". I have tried to split the text to 2 strings and add to the first my extra text then add him the second string. It worked but it is destroy my richTextBox1.SelectionColor (I got color...). So how can I add text without cutting my richTextBox1.Text or How can I save all the color data?
推荐答案您是否熟悉开始位置和结束位置?您可以简单地执行以下操作
Are you familiar with the starting position and ending positions ? you could simply do something like this
richTextBox1.SelectionStart = index; richTextBox1.SelectionLength = length;//you need to assign an integer where to start richTextBox1.SelectedText = "Good";它将用"Good"一词替换文本中您已为其指定长度的任何位置
it will replace whatever position in text where you have assigned length with the word "Good"
