Question

I\'m looking to write a large 2d array to an Excel worksheet using C#. If the array is 500 x 500, the code that I would use to write this is as follows:

 var st         


        

Answer 1

I just wrote a small example that worked for me. Originally found at SO this answer. I had to adapt this answer as in my Interop assembly (Excel 14 Object Library) there is no more method Worksheet.get_Range(.., ..)

var startCell = ws.Cells[1, 1];
int row = 500, col = 500;
var endCell = ws.Cells[row, col];
try
{
    // access range by Property and cells indicating start and end           
    var writeRange = ws.Range[startCell, endCell];
    writeRange.Value = myArray;
}
catch (COMException ex)
{
    Debug.WriteLine(ex.Message);
    Debugger.Break();
}
