从 vb.net 中的字符串中删除 img 标签 [英] Remove img tag from string in vb.net

问题描述

我的项目中有收件箱选项卡，我只想显示正文的 40 个字符，而不是所有正文.具有所有属性意味着完整的 src 但有时它不来意味着 src 可以被剪切.所以如何从正文中删除这个 img 标签并只获取简单的文本.

推荐答案

为了快速破解，您可以使用如下的正则表达式:

For a quick hack, you can use a regular expression like the following:

Dim input As String = "test<img>" ' your data here
Dim imgRegex As New Regex("<img[^>]*>", RegexOptions.IgnoreCase)
Dim output As String = imgRegex.Replace(input, "")

对于更一般的 HTML 解析，您应该使用 HTML Agility Pack.
