How do I get column names to print in this C# prog

Question

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 DataTable 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?
    }
}

Answer 1

foreach (DataRow row in dt.Rows)
{
    foreach (DataColumn column in dt.Columns)
    {
        ColumnName = column.ColumnName;
        ColumnData = row[column].ToString();
    }
}

Answer 2

You can access column name specifically like this too if you don't want to loop through all columns:

table.Columns[1].ColumnName

Answer 3

Print datatable rows with column

Here is solution 

DataTable datatableinfo= new DataTable();

// Fill data table 

//datatableinfo=fill by function or get data from database

//Print data table with rows and column


for (int j = 0; j < datatableinfo.Rows.Count; j++)
{
    for (int i = 0; i < datatableinfo.Columns.Count; i++)    
        {    
            Console.Write(datatableinfo.Columns[i].ColumnName + " ");    
            Console.WriteLine(datatableinfo.Rows[j].ItemArray[i]+" "); 
        }
}


Ouput :
ColumnName - row Value
ColumnName - row Value
ColumnName - row Value
ColumnName - row Value

Answer 4

You need to loop over loadDT.Columns, like this:

foreach (DataColumn column in loadDT.Columns)
{
    Console.Write("Item: ");
    Console.Write(column.ColumnName);
    Console.Write(" ");
    Console.WriteLine(row[column]);
}

Code for Find the Column Name same as using the Like in sql.

foreach (DataGridViewColumn column in GrdMarkBook.Columns)  
                      //GrdMarkBook is Data Grid name
{                      
    string HeaderName = column.HeaderText.ToString();

    //  This line Used for find any Column Have Name With Exam

    if (column.HeaderText.ToString().ToUpper().Contains("EXAM"))
    {
        int CoumnNo = column.Index;
    }
}
