Question

我有一个datagridview1，它有5列，我从datagridview2中添加到该gridview项，这没什么错，现在当我尝试使用2面额for循环从Datagridview1中获取这些值时，将其插入到我的sql db中，则显示此错误。

索引超出范围。必须为非负数且小于集合的大小。参数名称索引。

我希望我解释得很好。

Public Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Try

            con.ConnectionString = "Data Source = OMAR\MSSQLSERVER01;Initial Catalog=AccountsC20;Persist Security Info=True;User ID=ofamo;"
            con.Open()
            cmd.Connection = con



            Dim Selected = ListBox1.SelectedValue.ToString()
            If Selected = "0" Then
                MessageBox.Show("Make sure to select a valued product")
            Else
                MessageBox.Show((TextBox4.Text) + 1)

                For i As Integer = 0 To DataGridView1.RowCount - 1

                    For j As Integer = 0 To DataGridView1.ColumnCount - 1

                        cmd.CommandText = "Insert into SInvoice  Values('SIV-" & (TextBox4.Text) + 1 & "',0," & j + 1 & ",(select nodeno from productmast where arabic_name= '" & Selected & "')," & DataGridView1.Item(i, 2).Value & ",0.000000,'2019-04-04 13:40:00'," & DataGridView1.Item(i, 4).Value & "," & DataGridView1.Item(i, 3).Value & ",'',0,1,1,1,1,'04/04/2019 13:39:44','',1.000000,1,0,'','b',0.000000,5,0.000000," & DataGridView1.Item(i, 3).Value & ",'Nos',1.000000,'','','','','','','','','','','','','','','','','','','','','',0,3,'" & Label4.Text & "',1,1,1,1,1,1,0.000000)"
                        cmd.ExecuteNonQuery()

                    Next


                Next

您将以哪种方式填充datagridview 1或2？如果您使用的是喜欢数据表的数据，或者可以使用require_once("../../../../wp-load.php"); $buildName = $_POST['buildName']; $myBuild = $_POST['array']; $myBuild2 = json_decode('array'); echo $myBuild2; print_r($myBuild); $wpdb->insert('wp_usermeta', array( 'meta_key' => $buildName, 'meta_value' => $myBuild2 ), array( ) );非常轻松，快速地将数据传输到sql数据库，但是我不知道您是否希望这样做或是否使用数据表等。

sqlbulkcopy

尝试在每个循环中使用，看看是否有所不同

索引超出范围，并且必须为非负数并且小于集合的大小
