Multiple File Upload [ASP.NET 2.0]

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :.NET Framework



I got a new requirement for multiple files upload. User wants the directory structure(like explore) in left side and files structure in the right side. In our application developed using asp.net 2.0 and client shouldn’t allow to use third party controls.


can anyone provide any approach on this using asp.net .2.0 itself would be helpful for me.


Thanks & Regards,

Multiple File Upload Class


I'm using this example here:


And have added some GUID for unique filenames.

I'm in the middle of trying to get the 3 filenames as strings and thought I'd put it in an external class file, but when I build the page:

public class MultipleFileUploader
    public static Boolean doMultipleFileUploader(string sFileUpload01,
        string sFileUpload02, string sFileUpload03)
        HttpFileCollection uploadedFiles = Request.Files;
        string sFileGuid = System.Guid.NewGuid().ToString();
        for (int i = 0; i < uploadedFiles.Count; i++)
            HttpPostedFile userPostedFile = uploadedFiles[i];
                if (userPostedFile.ContentLength > 0)
                    string serverFileName = Path.GetFileName(userPostedFile.FileName);
                    string getFileExtension = Path.GetExtension(serverFileName);//get the file extension
                    string sSaveLocation = Server.MapPath(sFilePath + "/") + sFileGuid + getFileExtension;
                    string sFileName = sFileGuid + serverFileName;
                    string FinalFileName = sFileGuid + getFileExtension;

Upload a File to a SharePoint Document Library - Part I

The following helper class demonstrates a few techniques that allow documents to be uploaded to a SharePoint document library programmatically without using the API or a custom web service. You don't need to specify a document library name, and it will create any folders specified in the URL as required. File meta data will be updated if any properties are passed.

Asp.Net upload file access denied



I have the problem below, if anyone can help me, appreciate it.

Server Error in '/' Application.

Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Hig

File Upload to an .ashx Script.


Hoping that someone can help me with this. I've been tearing my hair out for days looking for sources and coming up with nothing.

Basically, the scenario is this: I'm working on a project whereby an iPhone will make an HTTP-POST call to an .ashx file on my site. The POST will consist of some fields and a file.

I'm having difficulty - read that as no luck what-so-ever - in finding the form fields or the file when I look at the HTTPContext object in the debug mode of Visual Studio. And if I look at HTTPContext.Request.Files.Count (where I would expect to find a file count) the value is always zero!!

Please help, very confused by this!



Using the single *.rpt file with multiple data sources


I've created a set of CrystalReports (*.rpt files) for an ASP.NET web app on a development server. I call each report using the following code:

protected void BTN_RunReport_Click(object sender, ImageClickEventArgs e)
CrystalReportViewer_ClientLetter.Visible = true;

ConnectionInfo con = new ConnectionInfo();
con.ServerName = Constants.ServerIP;
con.DatabaseName = Constants.DatabaseName;
con.UserID = Constants.UserID;
con.Password = Constants.Password;

CrystalReportViewer_ClientLetter.ReportSource = Server.MapPath(Constants.ClientLetters);
ParameterFields parameter = CrystalReportViewer_ClientLetter.ParameterFieldInfo;
ParameterField batchdate = new ParameterField();
batchdate.Name = "@BatchDate";
ParameterDiscreteValue batchdate_value = new ParameterDiscreteValue();
batchdate_value.Value = Convert.ToDateTime(txtBatchDate.Text);

foreach (TableLogOnInfo tlf in CrystalReportViewer_ClientLetter.LogOnInfo)
tlf.ConnectionInfo = con;

why I can not upload file to web by using WebClient.UploadFile method?



I am using WebClient.UploadFile method to upload a file to a web page.

The code is like this:

WebClient client = new WebClient(); 
byte[] responseBinary = client.UploadFile(url, fileName); 
string response = Encoding.UTF8.GetString(responseBinary);

But I can not upload it to server.

I used fiddler to see what happens, and it shows me the following information:

http status code: 302, request headers: POST /testing/upload/default.aspx HTTP/1.1

http status code: 302, request headers: GET /testing/upload/default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1

http status code: 200, request headers: GET /(X(1)S(22pynhvxd3eqsb455pudx145))/testing/upload/default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1

I would like to know, why I get 302 code, and why it redirect me to the strange url with (X(1)S(22pynhvxd3eqsb455pudx145)) ?

By the way, the web page is ok to upload file by using web explorer.
