Remove html markup from string

I am reading in a field from the database and displaying in a GridView and in that field it contains <br/> tags in the text. So I am trying to remove these from the code but when I check the value of e.Row.Cells[index].Text it doesn't contain <br/> and is has ;br/&gt; instead.

So I tried creating a function that removes any substring starting with < and ending with > or starting with & and ending with ;. The code removes the <> but it is still showing br/

Code:

index = gv.Columns.HeaderIndex("Message");
if (index > 0)
{
   string message = RemoveHTMLMarkup(e.Row.Cells[index].Text);
   e.Row.Cells[index].Text = message;
}

static string RemoveHTMLMarkup(string text)
{
        return Regex.Replace(Regex.Replace(text, "<.+?>", string.Empty), "&.+?;", string.Empty);
}

How do I remove the <br/> tag?

Being regardless of the question, I am curious about what this is:

Since this is a literal string, you (sh|c)ould only use String.Replace():

static string RemoveHTMLNewLines(string text)
{
    return text.Replace("&lt;br/&gt;", string.Empty);
}

Or replace with Environment.NewLine if needed.

  1. De-entitize the string.
  2. Then use regex to to find and remove expected tags.

Or

If you have enough time to study and Use, then use HtmlAgilityPack package.
