Hello everyone,
Am new to programming. I have project developed by a friend which am working on and tutoring myself on it. He has a database in an mdf file and has a code for the database back but i develop another project but using an sql database not like his in .mdf mine as a connection string to database in sql server but when i used his on code i got an error. below is his code and what do i need to modify.

private void databaseBackupToolStripMenuItem2_Click(object sender, EventArgs e)
       {
           try
           {
               Cursor = Cursors.WaitCursor;
               timer1.Enabled = true;
               if ((!System.IO.Directory.Exists("C:\\DBBackup")))
               {
                   System.IO.Directory.CreateDirectory("C:\\DBBackup");
               }
               string destdir = "C:\\DBBackup\\ERPS_DB " + DateTime.Now.ToString("dd-MM-yyyy_HH-mm-ss") + ".bak";
               con = new SqlConnection(cs.DBcon);
               con.Open();
               string cb = "backup database [" + System.Windows.Forms.Application.StartupPath + "\\ERPS_DB.mdf] to disk='" + destdir + "'with init,stats=10";
               cmd = new SqlCommand(cb);
               cmd.Connection = con;
               cmd.ExecuteReader();
               con.Close();
               st1 = User.Text;
               st2 = "Successfully backup the database";
               cf.LogFunc(st1, System.DateTime.Now, st2);
               MessageBox.Show("Successfully performed", "Database Backup", MessageBoxButtons.OK, MessageBoxIcon.Information);
           }
           catch (Exception ex)
           {
               MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
           }
       }

我的尝试：



i尝试将数据库名称从他自己的数据库名称更改为我自己的数据库名称，但似乎他在一个文件中，但我自己的数据库是在一个sql服务器中，它不包含在项目文件中他自己的

What I have tried:

i tried changing the database name from his own to my own database name but it seems his is in a file but my own database is in an sql sever which is not included in the project file like his own
