如何忽略文本框中的大小写 [英] how to ignore case in textbox

问题描述

这是我的代码

Hi this is my code

MResult = MResult.Replace(txtSearch.Text, "<span style=\"color:#c1330e; padding:0px 2px 0px 2px\">" + txtSearch.Text + "</span>");

在这里，我给出txtSearch.Text.tolower()只需要小写字母oly.
从文字文本中选择我的文本框文本是唯一的

如果我给小写或大写，它想正确显示.

here i give txtSearch.Text.tolower() it takes only lowecase oly.
here from literal text am selecting my textbox text alone

if i give lowecase or uppercase it want to show correctly. how can it work for all case?

推荐答案

尝试如下操作.

Try as below.

string MResult = "hdshdjshdjsinputhdjshdjhdINPUTDHSJHDJInputdhsdjshdjhdj";
string search = txtSearch.Text;//"input"
string replaceWith = "1234";
MResult = System.Text.RegularExpressions.Regex.Replace(MResult, search, replaceWith, System.Text.RegularExpressions.RegexOptions.IgnoreCase);

一个文本框将以您输入的格式(即大写或小写)存储文本-因此您不会遇到任何问题.
只是默认文本框应该可以正常工作.

A textbox will store text in the format (i.e. upper or lower case) you enter - so you should not be facing any problems in this.
Just the default text box should work correctly.
