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。

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)
