推荐答案
使用String.Replace或String.Trim很难删除数字之间的空格，因为它们是非常愚蠢的方法：它们只是寻找一个字符串并替换它 - 它们并不关心它在字符串中的位置。 br />
相反，试试一个正则表达式：
It's difficult to remove the space between numbers with String.Replace or String.Trim, because they are remarkably dumb methods: they just look for a string and replace it - they don't care where in the string it is.
Instead, try a Regex:
string input = " 2365 2365 ";
string output = Regex.Replace(input, @"(?<=\d+)\s+(?=\d+)", "");
这将删除数字组之间的所有空格并单独留下目的。
使用javascript进行正则表达式是否可行？
是 - 只需使用javascript替换方法：
Which will remove all the spaces between groups of numbers and leave the ends alone.
"is it possible in Regular Expression using javascript?"
Yes - just use the javascript Replace method:
<!DOCTYPE html>
<html>
<body>
<p>Click the button!</p>
<p id="demo"> 1234 5678 </p>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction()
{
var str = document.getElementById("demo").innerHTML;
var res = str.replace(/(\d+)(\s+)(\d+)/,"
1
3）;
document .getElementById（ demo).innerHTML=res;
}
< / 脚本 >
< / body >
< / html >
3"); document.getElementById("demo").innerHTML=res; } </script> </body> </html>
