Comment write some data to excel fichier(.xlsx)

[ForumBot]

This is what I am trying to do:

-

Create an Excel file (.xlsx) c://test/files/work1_4.13.14.xlsx with name + value (date).

example: work1_4.13.14.xlsx

-

Set headers to the file.

example: [Name] [Age] [City].

-

I have 3 `List` objects containing names, ages, and cities that I need to fill into the Excel sheet.

This is the format I would like the data to be in:

```
Name Age City
Ben 20 xyz
Jack 25 xyz
Mike 45 zyx

```

How can I send the data to the Excel sheet in this format?

Try this code

```
Microsoft.Office.Interop.Excel.Application oXL;
Microsoft.Office.Interop.Excel._Workbook oWB;
Microsoft.Office.Interop.Excel._Worksheet oSheet;
Microsoft.Office.Interop.Excel.Range oRng;
object misvalue = System.Reflection.Missing.Value;
try
{
//Start Excel and get Application object.
oXL = new Microsoft.Office.Interop.Excel.Application();
oXL.Visible = true;

//Get a new workbook.
oWB = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(""));
oSheet = (Microsoft.Office.Interop.Excel._Worksheet)oWB.ActiveSheet;

//Add table headers going cell by cell.
oSheet.Cells[1, 1] = "First Name";
oSheet.Cells[1, 2] = "Last Name";
oSheet.Cells[1, 3] = "Full Name";
oSheet.Cells[1, 4] = "Salary";

//Format A1:D1 as bold, vertical alignment = center.
oSheet.get_Range("A1", "D1").Font.Bold = true;
oSheet.get_Range("A1", "D1").VerticalAlignment =
Microsoft.Office.Interop.Excel.XlVAlign.xlVAlignCenter;

// Create an array to multiple values at once.
string[,] saNames = new string[5, 2];

saNames[0, 0] = "John";
saNames[0, 1] = "Smith";
saNames[1, 0] = "Tom";

saNames[4, 1] = "Johnson";

//Fill A2:B6 with an array of values (First and Last Names).
oSheet.get_Range("A2", "B6").Value2 = saNames;

//Fill C2:C6 with a relative formula (=A2 & " " & B2).
oRng = oSheet.get_Range("C2", "C6");
oRng.Formula = "=A2 & \" \" & B2";

//Fill D2:D6 with a formula(=RAND()*100000) and apply format.
oRng = oSheet.get_Range("D2", "D6");
oRng.Formula = "=RAND()*100000";
oRng.NumberFormat = "$0.00";

//AutoFit columns A:D.
oRng = oSheet.get_Range("A1", "D1");
oRng.EntireColumn.AutoFit();

oXL.Visible = false;
oXL.UserControl = false;
oWB.SaveAs("c:\\test\\test505.xls", Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing,
false, false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

oWB.Close();
oXL.Quit();
