Also new to linq2sql, does MyData direct to call stored_procedure ADDFILE in the database? or do we need to drag the ADDFILE sp into the O/R designer？
another question is how to read from database, and display it on page in asp.net? anyway, thanks a lot !

Great work Aneef,

I have a table in the DB called Documents. Instead of creating the stored proc, I just let LINQ do everything for me… Your “byte[] filebyte = FileUploader.FileBytes;” is just what I needed.

Document d = new Document
{
guid=Guid.NewGuid(),
file_ext=ext.Replace(“.”,”").Substring(0,3),
file_nm=file_name,
file_bin=file_binary,
is_active=true,
upload_page_type=rblLocation.SelectedValue,
upload_dt=DateTime.Now,
upload_by=Common.CurrentUserLogin
};

db.ControlDocuments.InsertOnSubmit(d);
db.SubmitChanges();

Hi Shyam,

LINQ Namespace is enough for this. you have to add a LINQ to SQL Class and Name it as MyData, this will create your MyDataDataContext Class for your use.
