Upload programatically multiple file with same name in doc lib then it shoud not replace the old one. It should create the new entry?

protected

void btnUpload_Click(object sender, EventArgs e)

{

if (fileUpload.HasFile)

{

if (fileUpload.PostedFile.ContentLength > 0)

{

string fileName = fileUpload.FileName;

using (SPWeb oWeb = siteUrl.OpenWeb())

{

oWeb.AllowUnsafeUpdates =

true;

SPDocumentLibrary docLib = oWeb.Lists["ETS-DocFile"] as SPDocumentLibrary;

string fileExtension = fileUpload.FileName.Substring(fileUpload.FileName.IndexOf("."));

byte[] fileByte = fileUpload.FileBytes;

string destUrl = fileName + fileExtension;

SPFile destFile = docLib.RootFolder.Files.Add(destUrl, fileByte, true);

destFile.Update();

oWeb.AllowUnsafeUpdates =

false;

}

}

}
