Answer 1

I think you want SqlDbType instead of sqldbtype

More info here

using System.Data.sqldbType.Nvarchar;

cmd.Parameters.Add("@BillNo", SqlDbType.NVarChar).Value = TextBox1.Text;
cmd.Parameters.Add("@CustomerName", SqlDbType.NVarChar).Value =TextBox2.Text;
cmd.Parameters.Add("@Address", SqlDbType.NVarChar).Value =TextBox3.Text;
cmd.Parameters.Add("@StartDate", SqlDbType.NVarChar).Value = Rdbsdate.SelectedDate;
cmd.Parameters.Add("@EndDate", SqlDbType.NVarChar).Value =Rdbddate.SelectedDate;
cmd.Parameters.Add("@Systemurl",SqlDbType.Image).Value= pic;
cmd.Parameters.Add("@Numberofcopies", SqlDbType.NVarChar).Value=TextBox7.Text;
cmd.Parameters.Add("@Amount", SqlDbType.NVarChar).Value = TextBox8.Text;
cmd.Parameters.Add("@Total",SqlDbType.NVarChar).Value= TextBox9.Text;

cmd.ExecuteNonQuery();

It appears as though you are trying to save a byte[] to your table ‘tblphotosetting’ but the corresponding field in the table (Systemurl) is expecting an item of data of type varchar. You need to decide what you actually want to save in that field and either adjust the table schema, or the database code.

So the desire is in fact to store an image in the systemUrl field of the table ‘tblphotosetting’. This field is currently a varchar so will need to be of type ‘Image’. The following SQL script will make this change.

alter table tblphotosetting 
    alter column Systemurl image null

Also there has been a bit of a theme in this question answer session whereby casing has not been used correctly in this C# code, therefore I would suggest that if an IDE is not already being used, then one can download and use Visual Studio Express for free.
