upload a file in SharePoint Document Library

[570enrico]

Hi
i'm new in programming SharePoint and i must realize an .NET application tha upload file in a document library and change the document propriety in this document library. In google i have found the nex code:

String fileToUpload = @"D:\TestSP.txt";
String sharePointSite = "http://yoursite.com/sites/Research/";

sharePointSite = "http://milsharep01/home.aspx";
String documentLibraryName = "Shared Documents";
using (SPSite oSite = new SPSite(sharePointSite))
{
using (SPWeb oWeb = oSite.OpenWeb())
{
if (!System.IO.File.Exists(fileToUpload))
throw new FileNotFoundException("File not found.", fileToUpload);
SPFolder myLibrary = oWeb.Folders[documentLibraryName];
// Prepare to upload
Boolean replaceExistingFiles = true;
String fileName = System.IO.Path.GetFileName(fileToUpload);
FileStream fileStream = File.OpenRead(fileToUpload);
// Upload document
SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);
// Commit
myLibrary.Update();
}
}
when i try to execute appeare the next error message:
"
The Web application at http://milsharep01/home.aspx could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application."
in istruction new SPSite(sharePointSite).
Where is my mistake? How can i do for solve this situation?
Where can i found some lab tha explain how solve my problem?

Thanks in advance

UploadFileToDocumentLibrary(@”C:\test.txt”, @”http://home-vs/Shared Documents/textfile.txt”);

and here is the function

public static bool UploadFileToDocumentLibrary(string sourceFilePath, string targetDocumentLibraryPath)

{

//Flag to indicate whether file was uploaded successfuly or not

bool isUploaded = true;

try

{

// Create a PUT Web request to upload the file.

WebRequest request = WebRequest.Create(targetDocumentLibraryPath);



//Set credentials of the current security context

request.Credentials = CredentialCache.DefaultCredentials;

request.Method = “PUT”;



// Create buffer to transfer file

byte[] fileBuffer = new byte[1024];



// Write the contents of the local file to the request stream.

using (Stream stream = request.GetRequestStream())

{

//Load the content from local file to stream

using (FileStream fsWorkbook = File.Open(sourceFilePath, FileMode.Open, FileAccess.Read))

{

//Get the start point

int startBuffer = fsWorkbook.Read(fileBuffer, 0, fileBuffer.Length);

for (int i = startBuffer; i > 0; i = fsWorkbook.Read(fileBuffer, 0, fileBuffer.Length))

{

stream.Write(fileBuffer, 0, i);

}



}

}



// Perform the PUT request

WebResponse response = request.GetResponse();



//Close response

response.Close();

}

catch (Exception ex)

{

//Set the flag to indiacte failure in uploading

isUploaded = false;

}



//Return the final upload status

return isUploaded;

}
