Hi I am uploading file from asp.net 3.5 to sharepoint server 2010.
My code is give below

WebResponse response = null;

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

request.Credentials = CredentialCache.DefaultNetworkCredentials;

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[1029120];

// 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)
{
L.Text = ex.Message.ToString() + "" + ex.Source.ToString() + "" + ex.StackTrace.ToString();
}
finally
{
// response.Close();
}

Its throw error is
The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse()

Thanks

Not at the moment. You code is kind of confusing to me.

I think it's bombing on the stream.write in the while loop. You can delete that code and run it to see if that clears the error 500.

I can post some sample code in vb that reads a file stream in bytes, so the bytes can be manipulated or altered.

This will read the stream 1 byte at a time, regardless of size. You can check for certain bytes to omit them, like the BOM marker. It reads 1 byte at a time, and when it reaches the linefeed, it creates a line array of bytes. You can just loop the bdx to build a byte array. I think this is what your trying to do, but I'm not clear on your intentions.

But you should get the principle of reading a file at the more advanced level, in which you can work and alter the data.

Sorry about the VB, that what I write in. the principle should be the same in c-sharp.
