Я развернул веб-часть в семействе сайтов.
Эта веб-часть пыталась прочитать содержимое документа в библиотеке документов.Он отлично работает в SharePoint 2007. Но это не работает в SharePoint 2010. Если размер документа небольшой, он работает нормально.в противном случае я получаю следующее исключение.
<code>

using (SPSite siteCol = new SPSite(siteurl))
{
using (SPWeb oWebsite = siteCol.OpenWeb())
{
oWebsite.AllowUnsafeUpdates = true;
SPFolder folder = oWebsite.GetFolder(folderurl);
SPFileCollection files = folder.Files;
SPFile file = files[filename];
Stream stream = file.OpenBinaryStream();
byte[] content = null;
BinaryReader reader = new BinaryReader(stream);
content = reader.ReadBytes((int)file.Length);//If the document size is higher, i am getting exception
oWebsite.AllowUnsafeUpdates = false;
}
}
Ошибка возникает, когда размер файла превышает 100 КБ.Пожалуйста, помогите мне решить эту проблему
