c# - copying of specific range of excel cells from one worksheet to another worksheet

Question

I am writing a C# program which copies a range of cells from a worksheet of one workbook to a worksheet of an other workbook. But the problem I am facing is I am only able to copy and paste the whole worksheet of first workbook. I want to know how to select only a specific range(from row 5 [column 1 to column 10] to row 100 [column 1 to column 10]) and paste it in second workbook worksheet starting from row 2 column 8.

Also i want to know how a fill a column say from C1 to C100 with some value in a direct way instead of using the loop like below

for(i=1;i<2;i++)
{
for(j=1;j<101;i++)
{
worksheet.cells[i,j]="Fixed";
}
}

Here is the code that i have written so far

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Excel = Microsoft.Office.Interop.Excel;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            Excel.Application srcxlApp;
            Excel.Workbook srcworkBook;
            Excel.Worksheet srcworkSheet;
            Excel.Range srcrange;
            Excel.Application destxlApp;
            Excel.Workbook destworkBook;
            Excel.Worksheet destworkSheet;
            Excel.Range destrange;
            string srcPath;
            string destPath;
//Opening of first worksheet and copying
            srcPath="C:\Documents and Settings\HARRY\Desktop\incident.csv";
            srcxlApp = new Excel.Application();
            srcworkBook = srcxlApp.Workbooks.Open(srcPath);
            srcworkSheet = srcworkBook.Worksheets.get_Item(1);
            srcrange = srcworkSheet.UsedRange;
            srcrange.Copy(Type.Missing);

//opening of the second worksheet and pasting
            destPath = "C:\Documents and Settings\HARRY\Desktop\FIXED Aging incident Report.xls";
            destxlApp = new Excel.Application();
            destworkBook = destxlApp.Workbooks.Open(destPath,0,false);
            destworkSheet = destworkBook.Worksheets.get_Item(1);
            destrange = destworkSheet.Cells[1, 1];
            destrange.Select();

            destworkSheet.Paste(Type.Missing, Type.Missing);
            destworkBook.SaveAs("C:\Documents and Settings\HARRY\Desktop\FIXED Aging incident Report " + DateTime.Now.ToString("MM_dd_yyyy") + ".xls");
            srcxlApp.Application.DisplayAlerts = false;
            destxlApp.Application.DisplayAlerts = false;
            destworkBook.Close(true, null, null);
            destxlApp.Quit();
            srcworkBook.Close(false, null, null);
            srcxlApp.Quit();

        }
    }
}

You should be able to do this:

        Excel.Range from = srcworkSheet.Range("C1:C100");
        Excel.Range to = destworkSheet.Range("C1:C100");

        from.Copy(to);
