How do I get column names to print in this C# program?
- by Kevin
I've cobbled together a C# program that takes a .csv file and writes it to a datatable. Using this program, I can loop through each row of the data table and print out the information contained in the row. The console output looks like this:
--- Row ---
Item: 1
Item: 545
Item: 507
Item: 484
Item: 501
I'd like to print the column name beside each value, as well, so that it looks like this:
--- Row ---
Item: 1 Hour
Item: 545 Day1 KW
Item: 507 Day2 KW
Item: 484 Day3 KW
Item: 501 Day4 KW
Can someone look at my code and tell me what I can add so that the column names will print? I am very new to C#, so please forgive me if I've overlooked something. Here is my code:
// Write load_forecast data to datatable.
DataTable loadDT = new DataTable();
StreamReader sr = new StreamReader(@"c:\load_forecast.csv");
string[] headers = sr.ReadLine().Split(',');
foreach (string header in headers)
{
loadDT.Columns.Add(header); // I've added the column headers here.
}
while (sr.Peek() > 0)
{
DataRow loadDR = loadDT.NewRow();
loadDR.ItemArray = sr.ReadLine().Split(',');
loadDT.Rows.Add(loadDR);
}
foreach (DataRow row in loadDT.Rows)
{
Console.WriteLine("--- Row ---");
foreach (var item in row.ItemArray)
{
Console.Write("Item:");
Console.WriteLine(item); // Can I add something here to also print the column names?
}
}
