System.ArgumentOutOfRangeException then add data to DataTable

[Slava]

Hello!

I use DataTable and AngleSharp.

Shows error while adding data to DataTable (below). Although there is no such error when using the standard VS DataGridView.What could be the problem?

System.ArgumentOutOfRangeException: The specified argument is out of range.Parameter name: index at AngleSharp.Common.ObjectExtensions.GetItemByIndex [T] (IEnumerable`1 items, Int32 index) at AngleSharp.Dom.HtmlCollection`1.get_Item (Int32 index)




My code:

private void Form1_Load(object sender, EventArgs e)

{

dt.Columns.Add("Ip", Type.GetType("System.String"));

dt.Columns.Add("Port", Type.GetType("System.String"));

dt.Columns.Add("Country", Type.GetType("System.String"));

dt.Columns.Add("Anonymity", Type.GetType("System.String"));

dt.Columns.Add("Google", Type.GetType("System.String"));

dt.Columns.Add("Https", Type.GetType("System.String"));

proxyGrid.ShowRowHeader = true;

proxyGrid.AllowFiltering = true;

proxyGrid.DataSource = dt;

}

async Task StartCrawl()

{

try

{

var config = Configuration.Default.WithDefaultLoader().WithCss().WithJs();

var address = "url";

var context = BrowsingContext.New(config);

var document = await context.OpenAsync(address);

var trs = document.QuerySelectorAll(".table-responsive tbody tr");

foreach (var item in trs)

{

if (item != null)

{

var tds = item.QuerySelectorAll("td");

if (tds != null)

{

dt.Rows.Add(new object[]

{

tds[0].TextContent,

tds[1].TextContent,

tds[3].TextContent,

tds[4].TextContent,

tds[5].TextContent,

tds[6].TextContent,

});

}

}

}

}

catch (Exception ex)

{

MessageBox.Show(ex.ToString());

}

finally

{

MessageBox.Show("Collect");

}

}

The problem has been resolved. Edited QuerySelector. True, it remained unclear why this did not occur in the standard DataGridView

Thanks
