No overload for method ' ' takes 8/11 arguments

Question

I have these two code snippets:

public void AddDocumentSet(string siteUrl, string libName, string docSetName, string mSISDN, string accountNumber, string hardCopyLocation, string verifiedBy, DateTime veriDate)
        {
          ClientContext clientContext = new ClientContext(siteUrl);
          Web web = clientContext.Web;
          List byTitle = clientContext.Web.Lists.GetByTitle(libName);
          clientContext.Load<Site>(clientContext.Site);
          ContentTypeCollection contentTypes = byTitle.ContentTypes;
          clientContext.Load<ContentTypeCollection>(contentTypes, (Expression<Func<ContentTypeCollection, object>>) (types => ClientObjectQueryableExtension.Include<ContentType>(types, new Expression<Func<ContentType, object>>[]
          {
            (Expression<Func<ContentType, object>>) (type => type.Id),
            (Expression<Func<ContentType, object>>) (type => type.Name),
            (Expression<Func<ContentType, object>>) (type => type.Parent)
          })));
          IEnumerable<ContentType> source = clientContext.LoadQuery<ContentType>(Queryable.Where<ContentType>((IQueryable<ContentType>) contentTypes, (Expression<Func<ContentType, bool>>) (c => c.Name == "Earchive document")));
          clientContext.ExecuteQuery();
          ContentType contentType = Enumerable.FirstOrDefault<ContentType>(source);
          ListItem listItem = byTitle.AddItem(new ListItemCreationInformation()
          {
            UnderlyingObjectType = FileSystemObjectType.Folder,
            LeafName = docSetName
          });
          listItem["ContentTypeId"] = (object) contentType.Id.ToString();
          listItem["Title"] = (object) "Documents for account ";
          listItem["MSISDN"] = (object) mSISDN;
          listItem["Account_x0020_Number"] = (object) accountNumber;
          listItem["Hard_x0020_Copy_x0020_Location"] = (object) hardCopyLocation;
          listItem["Verified by"] = (object) verifiedBy;
          listItem["Date of verification"] = (object) veriDate;
          listItem.Update();
          clientContext.Load<List>(byTitle);
          clientContext.ExecuteQuery();
        }




public void AddDocument(string siteUrl, string libName, string docListUrl, string docName, byte[] docStream, string mSISDN, string accountNumber, string hardCopyLocation, string documentName, string verifiedBy, DateTime veriDate)
    {
      ClientContext clientContext = new ClientContext(siteUrl);
      File file = clientContext.Web.Lists.GetByTitle(libName).RootFolder.Files.Add(new FileCreationInformation()
      {
        Content = docStream,
        Overwrite = false,
        Url = siteUrl + docListUrl + docName
      });
      file.ListItemAllFields["MSISDN"] = (object) mSISDN;
      file.ListItemAllFields["Account_x0020_Number"] = (object) accountNumber;
      file.ListItemAllFields["Hard_x0020_Copy_x0020_Location"] = (object) hardCopyLocation;
      file.ListItemAllFields["Document_x0020_Name"] = (object) documentName;
      file.ListItemAllFields["Verified by"] = (object) verifiedBy;
      file.ListItemAllFields["Date of Verification"] = (object) veriDate;
      file.ListItemAllFields.Update();
      clientContext.ExecuteQuery();

 

And I am calling them from another script C# script inside program.

r.AddDocumentSet(XXX +
Document.Field("Document Section 1\\Account").Value,
Document.Field("Document Section 1\\MSISDN").Value.ToString(),
Document.Field("Document Section 1\\Account").Value.ToString(),
Document.Field("Document Section 1\\Hard Copy Location").Value.ToString(),
Document.Field("Document Section 1\\Verified by").Value.ToString(),
Document.Field("Document Section 1\\Date of Verifica00tion").Value.ToString());
            Processing.ReportMessage("Document Set created. ");
}catch(System.Exception e){
Processing.ReportMessage("Document Set already exists. ");
}


r1.AddDocument(XXX +Document.Field("Document Section 1\\Account").Value+"/",
              "contract_"+
            Document.Field("Document Section 1\\Account").Value + "(" +
            Document.Field("Document Section 1\\MSISDN").Value + ").pdf", bytes
            , Document.Field("Document Section 1\\MSISDN").Value.ToString()
            , Document.Field("Document Section 1\\Account").Value.ToString()
            , Document.Field("Document Section 1\\Hard Copy Location").Value.ToString()
            , Document.Field("Document Section 1\\Document Name").Value.ToString()
            , Document.Field("Document Section 1\\Verified by").Value.ToString()
            , Document.Field("Document Section 1\\Date of Verifica00tion").Value.ToString());


}

And I get these errors:

No overload for method 'AddDocumentSet' takes '8' arguments (line 6, pos 1) No overload for method 'AddDocument' takes '11' arguments (line 69, pos 1)

I am not a C# rockstar but I have tried everything. rebuilt dll, rewriten the snippets again, but nothing helped. I hope someone could show me the right code.
