Also add the line below to the Page_Load Page.Form.Attributes.Add("enctype", "multipart/form-data"); 回答2: You cannot upload files using AJAX => you should not be placing a FileUpload control inside an UpdatePanel because this UpdatePanel sends an AJAX request to the server. 回答3: I also uploaded a file using the FileUpload

The C# language designers made the choice, when designing the language, that all

Even after fetching all the rows, rowcount stays at -1 . Is it a sqlite3 bug? I have already checked if there are rows in the table. I can get around this checking if a fetchone() returns something different than None , but I thought this issue would be nice to discuss. Thanks. 回答1: From the documentation : As required by the Python DB
