This should produce a nice table, but it does not work. It looks like escape characters not work. I print the text in an asp label.


private string GetTableData(DataTable dt)
    {

        StringBuilder TableData = new StringBuilder();
        // retrieve header row column labels
        TableData.AppendFormat("Row");
        foreach (DataColumn dc in dt.Columns)
        {
            TableData.AppendFormat("/t{0}", dc.ColumnName);
            TableData.AppendFormat("/t");
        }

        // retrieve rows
        int j = -1;
        foreach (DataRow dr in dt.Rows)
        {
            TableData.AppendFormat("[{0}]", ++j);
            foreach (DataColumn dc in dt.Columns)
            {
                TableData.AppendFormat("/t{0}", dr[dc]);
            }
            TableData.AppendFormat("/n");
        }

        return TableData.ToString();
    }

use the \ in place of the /

Change /t  to \t
and /n to \n

Strange

I try this

            StringBuilder TableData = new StringBuilder();
            TableData.AppendFormat("AA\tKK\tBB");
            TableData.AppendFormat("\n");
            TableData.AppendFormat("AAB\tBBK\tKK");
            Debug.WriteLine(TableData.ToString());

with gives me as result

AA      KK      BB
AAB      BBK      KK

With this code
        StringBuilder TableData = new StringBuilder();
        TableData.AppendFormat("AA\tKK\tBB");
        TableData.AppendFormat("\n");
        TableData.AppendFormat("AAB\tBBK\tKK");
        lblTest.Text = TableData.ToString(); //asp lable
I get just this is the output.

AA KK BB AAB BBK KK

Debug.WriteLine(TableData.ToString()); does not work in my asp.net 2.0 website in VS
