Error creating document from using list using Document Template

Question

Hi All,
I am trying to create a document from sharepoint list and upload it to a document library using item added and item updated event receiver methods. I can create metadata from list update in document library but unable to open the document. The error message
I get is "we're sorry. we can't open "Filename" because we found a problem with its contents. no error detail available". Please see the below code.
SPSecurity.RunWithElevatedPrivileges(delegate()
                   try
                       string TemplateUrl = string.Empty;
                       SPWeb web = properties.OpenWeb();
                       web.AllowUnsafeUpdates = true;
                       SPDocumentLibrary olist = web.Lists["NewLibList"] as SPDocumentLibrary;
                       String url = olist.RootFolder.ServerRelativeUrl.ToString();
                       SPFile file = null;
                       file = web.GetFile(olist.DocumentTemplateUrl);
                       if (file != null)
                           SPListItem oItems = properties.ListItem;
                           web.AllowUnsafeUpdates = true;
                           byte[] readStream = file.OpenBinary();
                           SPFile uploadedFile = olist.RootFolder.Files.Add("http://site/subsite/Libraryname/" + properties.ListItemId.ToString() + ".docx", readStream,
true);
                           SPListItem listitem = uploadedFile.Item;
                           listitem["Firstname"] = oItems["Firstname"];
                           listitem["Lastname"] = oItems["Lastname"];
                           if (uploadedFile.CheckOutType != SPFile.SPCheckOutType.None)
                               uploadedFile.CheckIn(string.Empty);
                           listitem.Update();
                           uploadedFile.Update();
                           web.AllowUnsafeUpdates = false;
                   catch (Exception ex)
                       EventLog.WriteEntry(EventLogName, ex.Message, EventLogEntryType.Error);

Hi,
Please try to use the code below:
SPSecurity.RunWithElevatedPrivileges(delegate()
try
string TemplateUrl = string.Empty;
SPWeb web = properties.OpenWeb();
web.AllowUnsafeUpdates = true;
SPDocumentLibrary olist = web.Lists["NewLibList"] as SPDocumentLibrary;
String url = olist.RootFolder.ServerRelativeUrl.ToString();
SPFile file = null;
file = web.GetFile(olist.DocumentTemplateUrl);
if (file != null)
SPListItem oItems = properties.ListItem;
web.AllowUnsafeUpdates = true;
Stream readStream = file.OpenBinaryStream(); //file is SPFile type
SPFile uploadedFile = olist.RootFolder.Files.Add("http://site/subsite/Libraryname/" + properties.ListItemId.ToString() + ".docx", readStream, true);
uploadedFile.CheckOut();
SPListItem listitem = uploadedFile.Item;
listitem["Firstname"] = oItems["Firstname"];
listitem["Lastname"] = oItems["Lastname"];
listitem.Update();
uploadedFile.Update();
uploadedFile.CheckIn(string.Empty);
web.AllowUnsafeUpdates = false;
catch (Exception ex)
EventLog.WriteEntry(EventLogName, ex.Message, EventLogEntryType.Error);
If the issue still exists, I suggest you dubug your code and check whether line of code error.
