C＃Windows窗体如何将Datagridview到数据库（SQL Server）？

Question

I need Insert data in Datagridview to Database in Sql Server 2008. But don't work.

".Rows(i)" Message Error:

'Non-invocable member 'System.Windows.Forms.DataGridView.Rows' cannot be used like a method.'

Code C# (Windows Form)

SqlConnection Conn = new SqlConnection();
SqlCommand cmd = new SqlCommand();
StringBuilder sb = new StringBuilder();
SqlTransaction tr;

private void testExcel_Load(object sender, EventArgs e)
{
    string appConn = ConfigurationManager.ConnectionStrings["connDB"].ConnectionString;
    Conn = new SqlConnection();
    if (Conn.State == ConnectionState.Open)
    {
        Conn.Close();

    }
    Conn.ConnectionString = appConn;
    Conn.Open();
}

private void button2_Click(object sender, EventArgs e)
{
    tr = Conn.BeginTransaction();

    sb.Remove(0, sb.Length);
    sb.Append("INSERT INTO tableAset (Id,AsId,AsRefid,Invid,TypeName)");
    sb.Append("VALUES (@Id,@AsId,@AsRefid,@Invid,@TypeName)");
    string sqlSave = sb.ToString();

    for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
    {     
      cmd.CommandText = sqlSave;
      cmd.CommandType = CommandType.Text;
      cmd.Connection = Conn;
      cmd.Transaction = tr;
      cmd.Parameters.Clear();

      cmd.Parameters.Add("@Id", SqlDbType.Int).Value = dataGridView1.Rows(i).Cells(0).Value;
      cmd.Parameters.Add("@AsId", SqlDbType.VarChar).Value = dataGridView1.Rows(i).Cells(1).Value;
      cmd.Parameters.Add("@AsRefid", SqlDbType.VarChar).Value = dataGridView1.Rows(i).Cells(2).Value;
      cmd.Parameters.Add("@Invid", SqlDbType.VarChar).Value = dataGridView1.Rows(i).Cells(3).Value;
      cmd.Parameters.Add("@TypeName", SqlDbType.VarChar).Value = dataGridView1.Rows(i).Cells(4).Value;

      cmd.ExecuteNonQuery();
      tr.Commit();
      MessageBox.Show("It's Done!", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
    }
}

Thank you very much for your time. :)

Answer 1

You should use rows[i] instead, the same goes for the Cells:

dataGridView1.Rows[i].Cells[0].Value

Take a look at the Rows property

Answer 2

只需用方括号替换圆括号

dataGridView1.Rows[i].Cells[0].Value;

Answer 3

I recommend to use SqlBulkCopy.You can easily get the GridView data in DataTable format and you can pass the DataTable to SqlBulkCopy WriteToServer You can check this example. https://www.aspsnippets.com/Articles/Using-SqlBulkCopy-to-insert-bulk-data-from-GridView-to-database-in-ASPNet.aspx
