我有一个SharePoint日历事件,可以将任何类型的文件作为附件。有没有办法访问文件的内容/下载它们?我必须计算这些文件的校验和。

string siteURL = "http://yourserver/yourpathtothesite";
using (SPSite site = new SPSite(siteURL))
{
using (SPWeb web = site.OpenWeb())
{
string listName = "Events";
SPList calendarList = web.Lists[listName];
// get whatever item you are interested in
SPListItem item = calendarList.GetItemById(1);
foreach (String attachmentname in item.Attachments)
{
String attachmentAbsoluteURL = item.Attachments.UrlPrefix + attachmentname;
// To get the SPSile reference to the attachment just use this code
SPFile attachmentFile = web.GetFile(attachmentAbsoluteURL);
// To read the file content simply use this code
Stream stream = attachmentFile.OpenBinaryStream();
StreamReader reader = new StreamReader(stream);
String fileContent = reader.ReadToEnd();
}
}
}
