I am uploading file from application to sharepoint document library.
upto 50MB Files uploading well.when i upload more than 50MB its not allowing.

my IIS is IIS 6.0.

how to do that.

in sharepoint document library under WEB APPLICATION GENERAL SETTING i have set

file upload size to 200MB But its not working.

and web.config i added this:

<httpruntime executiontimeout="3600">

here is my code:

protected void btnUpload_Click(object sender, EventArgs e)
string uploadedFilePath = @"E:\New Folder\";
string sharePointListPath =

if (FileUpload1.HasFile)
uploadedFilePath + FileUpload1.FileName);

Label1.Text = "File name: " +
FileUpload1.PostedFile.FileName + "
" +
FileUpload1.PostedFile.ContentLength + " bytes
" +
"Content type: " +

uploadedFilePath + FileUpload1.FileName,
sharePointListPath + FileUpload1.FileName);
catch (Exception ex)
Label1.Text = "ERROR: " + ex.Message.ToString();
Label1.Text = "You have not specified a file.";

protected void UploadFileToSharePoint(string UploadedFilePath,string SharePointPath)
WebResponse response =null;

// Create a PUT Web request to upload the file.
WebRequest request = WebRequest.Create(SharePointPath);

request.Credentials = CredentialCache.DefaultCredentials;

request.Method = "PUT";

// Allocate a 1 KB buffer to transfer the file contents.
// You can adjust the buffer size as needed, depending on
// the number and size of files being uploaded.
byte[] buffer = new byte[1024];

// Write the contents of the local file to the
// request stream.
using (Stream stream = request.GetRequestStream())
using (FileStream fsWorkbook = File.Open(UploadedFilePath,
FileMode.Open, FileAccess.Read))
int i = fsWorkbook.Read(buffer, 0, buffer.Length);

while (i > 0)
stream.Write(buffer, 0, i);
i = fsWorkbook.Read(buffer, 0, buffer.Length);

// Make the PUT request.
response = request.GetResponse();
catch (Exception ex)
throw ex;

Generally, the uploading limit of ASP.NET FileUploader is 4MB. But you can increase the limit of length of uploaded file by using the following code into your web.config file in your website.

<httpruntime maxrequestlength="20480" executiontimeout="600">

he source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

2) Add the following section to the configuration file of your application:



<compilation debug="true">
