How would i be able to present this information in a rich text box or any type of visual outputs. C#

Question

This is the code and i need to present the output on screen in a windows form. Would prefer if it is a text box.

var res = (from x in dt.AsEnumerable()
           group x by (string)x["Weather"] into y
           select new { Key = y.Key, Count = y.Count() }).ToArray();

Answer 1

https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/creating-a-datatable-from-a-query-linq-to-dataset Indicates this should be possible:

var res = from x in dt.AsEnumerable()
       group x by (string)x["Weather"] into y
       select new { Key = y.Key, Count = y.Count() };

var newdt = res.CopyToDataTable();

datagridview1.DataSouce = newdt;

All that remains is for you to drop a DataGridView control on your form, Ensure it's AutoGenerateColumns property is set to true, and give it a better name than datagridview1 (on the form and in the code above)

Answer 2

You can get the data to List

var r = (from x in test.AsEnumerable()
                 group x by (string) x["Weather"] into y
                 select new
                     {
                     Key = y.Key, Count = y.Count()
                     }).ToList();

Then Iterate and get all the data to string and assign that to textbox.Text Property.

 string result = "";
        foreach ( var weatherData in r )
            {
            result += weatherData.Key + " " + weatherData.Count + "\r\n";
            }
myTextBox.Text = result;
