        {
            HttpFileCollection uploads = HttpContext.Current.Request.Files;
            for (int i = 0; i < uploads.Count; i++)
            {
                HttpPostedFile upload = uploads[i];

                if (upload.ContentLength == 0)
                    continue;


                string c = System.IO.Path.GetFileName(upload.FileName);
                string filename = System.IO.Path.GetFileNameWithoutExtension(upload.FileName);
                string extension = System.IO.Path.GetExtension(upload.FileName);

                string nfilepath;
                nfilepath = "D:\\saravana\\Spatiotemporal Approach\\SourceMain\\source_uploadfiles\\" + c;

                catch (Exception Exp)
                {

                cmd.Connection = con;
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = "insert into filedetails(filename,filetype,filepath) values('" + filename + "','" + extension + "','" + nfilepath + "')";

                    con.Close();

            }
        }

推荐答案

您可能没有引用程序集"System.Web".它与.NET Framework捆绑在一起，因此在GAC中，在添加引用"窗口的.NET选项卡中引用.该类型的全名是System.Web.HttpFileCollection， http://msdn.microsoft.com /en-us/library/system.web.httpfilecollection.aspx [ ^ ].

You probably did not reference the assembly "System.Web". It''s bundled with .NET Framework, so it''s in the GAC, referenced in a .NET tab of the window "Add Reference". The full name of the type is System.Web.HttpFileCollection, http://msdn.microsoft.com/en-us/library/system.web.httpfilecollection.aspx[^].

命名空间为System.Web
