字符串替换 [英] string replace

问题描述

我是.net的新手.
如何替换字符串，这意味着当我在TextBox中输入一些文本并且要从数据库中检索值时，我想通过在结果中突出显示该文本来显示在TextBox中输入的内容.

我该怎么做?

Hi,

I am new to .net.
How can I replace a string, that means when I enter some text in a TextBox and I am retrieving a value from database, I want to display what I entered in the TextBox by highlighting that text in the result.

How can I do that?

推荐答案

试试看:

Try this:

String toHighlight = textBoxX.Text;
String dataFromDatabase = GetDBResult(); //I assume reading from the DB was not part of your problem
String startHighlightTag = "<span class=\"highlight\">"
String endHighLighTag = "</span>";

String dataToRender = dataFromDatabase.Replace(toHighlight, startHighLightTag + toHighLight + endHighlightTag);

//output dataToRender to a div or whatever

您必须对类突出显示有一些CSS定义，以便突出显示看起来完全符合您的要求.

干杯

You''ll have to have some CSS definition for the class highlight so that the highlighting looks exactly as you want.
