File Uploading control in asp.net

When i start my code with file upload control it's all over, but i have to fight with my exception
with exception message of string or binary data would be truncated.I cannot come to know which binary data would be truncated
and also i had created a table of name INFORMATION with columns id,name,photo
query=create table information (id int,name varchar(size),photo varbinary(max))
id=some number
name=name of the uploaded file
photo=content of uploaded file(eg:->JPEG OR PPG..ETC)
and also i had taken one textbox to enter id no and one fileuploadcontrol and one button(upload)
here is my front end code

protected void btnupload_Click(object sender, EventArgs e)
{
    string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
    string contenttype=FileUpload1.PostedFile.ContentType;
    using (Stream fs=FileUpload1.PostedFile.InputStream)
    {
        using (BinaryReader br=new BinaryReader(fs))
        {
         byte[] bt = br.ReadBytes((int)fs.Length);
         string constr = ConfigurationManager.ConnectionStrings["naveen"].ToString();
            using (SqlConnection con=new SqlConnection(constr))
            {
                string query = "insert into information values(@id,@name,@photo)";
                using (SqlCommand cmd=new SqlCommand(query))
                {
                    cmd.Connection = con;
                    cmd.CommandText = query;
                    cmd.Parameters.AddWithValue("@id", TextBox1.Text);
                    cmd.Parameters.AddWithValue("@name", filename);
                    cmd.Parameters.AddWithValue("@photo", contenttype);
                    con.Open();
                    int i=cmd.ExecuteNonQuery();----->Here is the statement which i have got exception
                    con.Close();
                    if (i>0)
                    {
                        Label1.Text = "File uploaded succesfully";
                    }
                    else
                    {
                        Label1.Text = "failed to upload";
                    }
                }
            }

        }
    }
}
