我该如何移除 <p></p> 从C＃中的字符串末尾开始（如果存在）？

Question

Can someone help suggest how I can create a function that will trim off some text if it appears at the end of a string in C#. What I have is some strings that end with:

<p>&nbsp;</p>

So for example var a = "sometext<p>&nbsp;</p>";

I know that I can use text.EndsWith("<p>&nbsp;</p>") to detect if it matches but then how could I remove that?

Answer 1

You could use a regular expression

Regex.Replace(text, "<p>&nbsp;</p>$", "")

This way, you don't have to check .EndsWith("<p>&nbsp;</p>")

Answer 2

假设您只想删除标记，如果标记位于标记的结尾，请使用：

text.Substring(0, text.Length - "<p>&nbsp;</p>".Length);

Answer 3

I would use LastIndexOf and Substring:

string toReplace = "<p>&nbsp;</p>";
if(a.EndsWith(toReplace)) a.Substring(0, a.LastIndexOf(toReplace));

Answer 4

try this:

RemoveFromEndIfContains("<p>&nbsp;</p>");


function string RemoveFromEndIfContains(string text, string remove)
{
if (text.EndsWith())
  return text.Substring(0, text.Length - remove.Length);
else
  return text;
}

Answer 5

text.Remove(text.Length - "<p>&nbsp;</p>".Length);

从该字符串中删除从指定位置开始到最后一个位置的所有字符。
