Programmatically getting the last filled excel row using C#

Couple ways, 

using Excel = Microsoft.Office.Interop.Excel;

Excel.ApplicationClass excel = new Excel.ApplicationClass();
Excel.Application app = excel.Application;
Excel.Range all = app.get_Range("A1:H10", Type.Missing);

OR

Excel.Range last = sheet.Cells.SpecialCells(Excel.XlCellType.xlCellTypeLastCell, Type.Missing);
Excel.Range range = sheet.get_Range("A1", last);

int lastUsedRow = last.Row;
int lastUsedColumn = last.Column;

This is a common issue in Excel.

Here is some C# code:

// Find the last real row
nInLastRow = oSheet.Cells.Find("*",System.Reflection.Missing.Value, 
System.Reflection.Missing.Value, System.Reflection.Missing.Value,    Excel.XlSearchOrder.xlByRows,Excel.XlSearchDirection.xlPrevious, false,System.Reflection.Missing.Value,System.Reflection.Missing.Value).Row;

// Find the last real column
nInLastCol = oSheet.Cells.Find("*", System.Reflection.Missing.Value,     System.Reflection.Missing.Value,System.Reflection.Missing.Value, Excel.XlSearchOrder.xlByColumns,Excel.XlSearchDirection.xlPrevious,    false,System.Reflection.Missing.Value,System.Reflection.Missing.Value).Column;

or using SpecialCells

Excel.Range last = sheet.Cells.SpecialCells(Excel.XlCellType.xlCellTypeLastCell, Type.Missing);
Excel.Range range = sheet.get_Range("A1", last);

Pryank's answer is what worked closest for me. I added a little bit towards the end (.Row) so I am not just returning a range, but an integer.

int lastRow = wkSheet.Cells.SpecialCells(XlCellType.xlCellTypeLastCell, Type.Missing).Row;
