GridFSFileInfo fileInfo;
var options = new GridFSFindOptions
{
Limit = 1
};
FilterDefinition<GridFSFileInfo> filterDefinition = Builders<GridFSFileInfo>.Filter
.Where(ee => ee.Id.Equals(new ObjectId(fileId)));
using (var cursor = _mongoDbHelper.Bucket.Find(filterDefinition, options))
{
fileInfo = cursor.ToList().FirstOrDefault();
}
byte[] file = _mongoDbHelper.Bucket.DownloadAsBytes(new ObjectId(fileId));
UploadedFile uploadedFile = new UploadedFile(fileInfo.Filename, file);
return uploadedFile;
我使用MongoDB的V2在C#中,我想通過給FILEID但在網上downaload的byte []和另外獲取文件名:MongoDB的V2 C#獲取文件名
_mongoDbHelper.Bucket.Find(filterDefinition, options)
其拋我一個例外:
System.InvalidOperationException
和消息是:
{document} .Id不受支持。
但是GridFSFileInfo具有屬性名稱ID。 我如何找到文件名?
