  • 万恶的剪贴板==》为存储而生

    近几天逆天经常大量复制粘贴一些图文信息,在某些特定的场合,图片都是无法直接粘贴进去的,就比如博客园的编辑器。

    源码:https://github.com/dunitian/DNTLive/tree/master/Software/万恶剪贴板

    要弄个什么还要把word里面的图片或者网上的图片先弄出来,这是多么的蛋疼啊~

    于是就有了万恶的剪贴板==》为存储而生

    其实是个很简单的功能点==》稍微说下核心代码

    获取文本内容var dataStr = Clipboard.GetText();

    获取单个图片var imgObj = Clipboard.GetImage();

    获取图文格式(网页或者Word之类的)

    var data = Clipboard.GetDataObject();
    if (data.GetDataPresent(DataFormats.Html, true))
    {
      return data.GetData(DataFormats.Html, true).ToString();
    }

    正则匹配图片:Regex.Matches(dataStr, @"<img([^>]*)s*src=('|"")([^'""]+)('|"")", RegexOptions.ECMAScript)

    异步批量下载图片:webClient.DownloadFileAsync(uri,path)

    贴代码:
