我有一个Windows表单,它将永远将数据加载到我的datagridview中.

我一直在这行中得到错误:

    dataGridView1.Rows.Add(row);

跨线程操作无效:控制'dataGridView1'从其创建的线程以外的线程访问.

这是我的代码:

    public List<string> _checked = new List<string>();

    private void getBarcodProperty()
    {                
        string query = "select Name from RfidUnic where Barcode = @barcode";

        while (true)
        {
            while (_checked.Count > 0)
            {
                SQLiteCommand cmd = new SQLiteCommand(query, sqliteConnection);
                cmd.Parameters.AddWithValue("@barcode", _checked[0]);
                sqliteConnection.Open();

                SQLiteDataReader da = cmd.ExecuteReader();

                if (da.Read())
                {
                    if (!da.IsDBNull(0))
                    {
                        string[] row = new string[] { da[0].ToString(), "1", _checked[0] };
                        dataGridView1.Rows.Add(row);
                        _checked.RemoveAt(0);
                    }
                }
                else
                {
                    string[] row = new string[] { "empty", "1", _checked[0] };
                    dataGridView1.Rows.Add(row); …
