This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. And I have no idea what you mean by "assign it into excel" for example, or what help you actually need.

Your question is a bit ambiguous, nevertheless, here is how you can export datatable into excel file:
--------
string directory = @"C:\NOTES";

if (!Directory.Exists(directory))
Directory.CreateDirectory(directory);

var dataTable = ExcelTable();

var workbook = new ExcelFile();
var worksheet = workbook.Worksheets.Add("Sheet1");
worksheet.InsertDataTable(dataTable, new InsertDataTableOptions() { ColumnHeaders = true });

var table = worksheet.Tables.Add("InformationTable", worksheet.GetUsedCellRange(true), true);
table.BuiltInStyle = BuiltInTableStyleName.TableStyleMedium2;

workbook.Save(Path.Combine(directory, "InformationTable.xlsx"));
--------

If you need to print an excel file from c# then just add this:

--------
workbook.Print("Your printer's name or use 'null' for default printer.");
--------

According to ApplicationClass Class (Microsoft.Office.Interop.Excel) | Microsoft Docs[^], the Application class does not contain a CreateDirectory method. You need to use the Save or SaveAs method from the WorkBook class.

You should also not create folders in the root of the C: drive; there are much better places to save your data - see Where should I store my data?[^].
