SharePoint 2010 ——自定义上传页面与多文件上传解决方案

最近项目遇到一个很麻烦的问题，原以为很容易解决，结果搞了那么久，先开个头，再慢慢写

1.创建Sharepoint空白项目，创建应用程序页面，创建custom action,

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <CustomAction Description="Customize the upload.aspx file for a document library"
               RegistrationType="List"
                RegistrationId="101"
                GroupId="Permissions"
                Id="05511583-fb44-4eca-817a-45892250da9e"
                Location="Microsoft.SharePoint.ListEdit"
                Sequence="1000"
                Title="Customize Upload Form (TCL SUNJUNLIN)"
                >
    <UrlAction Url="~site/_layouts/Custom.ApplicationPage/SetCustomUploadProperties.aspx?List={ListId}" />
  </CustomAction>
</Elements>

3.编写自定义上传页面；
