I parse table from a Html table, that has 4 columns, and then i write that into a Database, using Sqlbulkcopy.

i need to be able to add a value from a textbox to the array/list before i bulk upload. This is so i can reference based on a machine name from a database ?

C#

string Url = "http://" + TextBox1.Text + "/logs/Logfile.html";

HtmlAgilityPack.HtmlWeb WebPage = new HtmlAgilityPack.HtmlWeb();

            HtmlAgilityPack.HtmlDocument document = WebPage.Load(Url);


            var table = new DataTable("Sample Table");


            table.Columns.Add("Entry", typeof(string));
            table.Columns.Add("Date", typeof(string));
            table.Columns.Add("Time", typeof(string));
            table.Columns.Add("Description", typeof(string));
            table.Columns.Add("Server", typeof(string));

            var nodes = document.DocumentNode.SelectNodes("//table[7]/tr[position() > 1]");


            nodes

            .Skip(1) // skips for headers
            .Select(tr => tr.Elements("td").Select(td => td.InnerText.Trim())
            .ToArray())
            .ToList()
            .ForEach(row => table.Rows.Add(row));


            using (SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
            {
                conn.Open();
                using (SqlBulkCopy copy = new SqlBulkCopy(conn))
                {

                    copy.DestinationTableName = "LogEntries";
                    copy.WriteToServer(table);

                    conn.Close();
                }
            }

Solution 1

it's not clear what exactly you want to write, so I made just an example:

C#

table.Rows.Add("entry", "date", "time", textBox1.Text, "server");

Hi mark, I Parse a data Table from a Html File (below), as per the Below, there are multiple Rows in the Html File ( it's a Log file), all the log entries are retrieved from the Html File. That Works no problem ( about 40 entries ), Each of these log files sit on Different servers, so i have a Textbox, where the Server name is Typed, and will then retrieve the Log File.

I Need to add the Textbox1.text Value into the Datatable,the Datatable is Filled with the log entries using the .ForEach(row => table.Rows.Add(row));... if that is changed to include the Textbox1.text, then the Data is Blank, for the Ammount of Rows..

<table border="0" cellpadding="2" width="100%">
<tr bgcolor="#F7F7FF">
<th>Entry</th>
<th>Date</th>
<th>Time</th>
<th>Description</th>
</tr>
<tr bgcolor="#F0F0FF">
<td>BLANK ROW</td> !! This is Skipped with the "/tr[position() > 1]"
<td>ENTRY NUMBER</td>
<td>DATE</td>
<td>TIME</td>
<td>Description HERE</td>
</tr>

Solution 2

I think you mean like this example. I'm not used to adding all methods behind eachother as you do with the nodes object. Maybe there is also a way to add the server to the list, but I would do it this way:

C#

string Url = "http://" + TextBox1.Text + "/logs/Logfile.html";
 
HtmlAgilityPack.HtmlWeb WebPage = new HtmlAgilityPack.HtmlWeb();
 
            HtmlAgilityPack.HtmlDocument document = WebPage.Load(Url);
 

            var table = new DataTable("Sample Table");
 

            table.Columns.Add("Entry", typeof(string));
            table.Columns.Add("Date", typeof(string));
            table.Columns.Add("Time", typeof(string));
            table.Columns.Add("Description", typeof(string));
            table.Columns.Add("Server", typeof(string));
 
            var nodes = document.DocumentNode.SelectNodes("//table[7]/tr[position() > 1]");
 

            nodes
 
            .Skip(1) // skips for headers
            .Select(tr => tr.Elements("td").Select(td => td.InnerText.Trim())
            .ToArray())
            .ToList()
            .ForEach(row => table.Rows.Add(row));
 

            for(DataRow row in table.Rows)
               row["Server"] = TextBox1.Text;

            using (SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
            {
                conn.Open();
                using (SqlBulkCopy copy = new SqlBulkCopy(conn))
                {
 
                    copy.DestinationTableName = "LogEntries";
                    copy.WriteToServer(table);
 
                    conn.Close();
                }
            }

VB

nodes

            .Skip(1) // skips for headers
            .Select(tr => tr.Elements("td").Select(td => td.InnerText.Trim())
            .ToArray())
            .ToList()
            .ForEach(row => table.Rows.Add(row));


DataColumn Servcol = new DataColumn("CloudServer", typeof(String));

table.Columns.Add("Servcol");

foreach (DataRow row in table.Rows)
                      {
                         row["servcol"] = txt_Server.Text;
                     }

works Like a Charm....

for the Input, Put me in the Right direction
