我有一个时区感知对象：
date = timezone.now()
然后我使用一些中间件获取用户的时区，所以我把它作为一个字符串，如：
tz = "America/New_York"
这可能是一个非常简单的问题，但我无法在任何地方找到答案：如何将日期对象的时区更改为用户的时区？我试过date.localize(tz)，但这给了我一个错误。我做错了什么。
答案 0 :(得分：0)
您需要将字符串转换为时区对象，然后使用 static void Main(string[] args)
{
using (ClientContext context = new ClientContext(sp_site_address))
{
context.AuthenticationMode = ClientAuthenticationMode.FormsAuthentication;
context.FormsAuthenticationLoginInfo = new FormsAuthenticationLoginInfo(username, pwd);
List list = context.Web.Lists.GetByTitle(requests_list_name);
CamlQuery query = new CamlQuery();
query.ViewXml = "<View><RowLimit>100</RowLimit></View>";
ListItemCollection items = list.GetItems(query);
context.Load(items);
context.ExecuteQuery();
foreach (ListItem oListItem in items)
{
FileCollection files = GetAttachments(context, list, oListItem);
foreach (Microsoft.SharePoint.Client.File f in files)
{
Download(f.ServerRelativeUrl, FolderToSaveTo, context, f.Name);
}
lstRequests.Add(Agreement);
}
}
}
public static FileCollection GetAttachments(ClientContext ctx, List list, ListItem item)
{
ctx.Load(list, l => l.RootFolder.ServerRelativeUrl);
ctx.Load(ctx.Site, s => s.Url);
ctx.ExecuteQuery();
Folder attFolder = ctx.Web.GetFolderByServerRelativeUrl(list.RootFolder.ServerRelativeUrl + "/Attachments/" + item.Id);
FileCollection files = attFolder.Files;
ctx.Load(files, fs => fs.Include(f => f.ServerRelativeUrl, f => f.Name, f => f.ServerRelativeUrl));
ctx.ExecuteQuery();
return files;
}
public static void Download(string serverFilePath, string destPath, ClientContext context, string filename)
{
using (FileInformation ffl = Microsoft.SharePoint.Client.File.OpenBinaryDirect(context, serverFilePath))
{
if (System.IO.Directory.Exists(destPath))
{
using (FileStream fileStream = System.IO.File.Create(destPath + "\\" + filename))
{
using (MemoryStream stream = new MemoryStream())
{
ffl.Stream.CopyTo(stream);
stream.WriteTo(fileStream);
}
}
}
}
}
