Question

我的上传表单显示两条错误消息，即使我的文件是36kb并且它说它们超过100000，它仍然似乎无法正常工作。发生了什么？我正在从一个Web表单进行测试，当将控件放在服务器上时，它根本不输出更新的错误消息，而是输出旧消息。此外，它不是一次正确上传到文件结构（从事物的外观在同一文件夹内）

    //this code checks if the fileupload control has input inside it, then proceeds to the next page with the document saved.
    public partial class UploadFileControl : System.Web.UI.UserControl

        {

        }

您确定ContentLength系列吗？也许如果你改变这个

if (FileUploadControl.PostedFile.ContentLength < 10000)

到这个

if (FileUploadControl.PostedFile.ContentLength < 10485760) // 10mb

代码将成功运行

上传不正常，不会给出正确的消息/文件太大/错误的文档类型
