Question

i am try to get data from excel file and save it in int [] array=new int[9]; want to do this using for loop , in order to get value from file "one row at a time" . i done with reading data fro file but couldont store it into int [] through iteration.

    static void Main()
    {
        string i="B1410";
        string j="J1410";
        Excel.Application xlApp = new Excel.Application();
   Excel.Workbook xlWorkbook = 

    xlApp.Workbooks.Open(@"E:\Normalized_sheet1.xlsx");
        string currentsheet = "Sheet1";
        Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[currentsheet];
        Excel.Range xlRange = xlWorksheet.get_Range(i, j.ToString());
        Object[,] valueArray = 

     (Object[,])xlRange.get_Value(Excel.XlRangeValueDataType.
    xlRangeValueDefault);
      int[] array = new int[9];

       array =  Convert.ToInt32((Object[,])xlRange.get_Value
                 (Excel.XlRangeValueDataType.xlRangeV    
                  alueDefault.ToString()));   //Error

        // Release Com object by decrementing the reference count

        xlApp.Quit();
        Console.ReadLine();

   }

Answer 1

Your array is only scoped to the for loop.

for (int k = 1; k < 500; k++)
{
    int[] array = new int[9];
}

Declare it outside.

int[] array = new int[9];
for (int k = 1; k < 500; k++)
{
    // ...
}

Answer 2

Your array is only 9 elements long, but k can by up to 499 . You can't insert one element into this array per iteration of the for loop as you'll get in IndexOutOfBoundsException thrown.

array probably needs to be the same size as the max value of k , ie 499.
