Question

I am sure this is quite simple but I cannot seem to get this right.
I have a built up a ICollection of Users. This collection could have 1 or many.
I now want to loop through this collection and assign a variable to each user that I can then use to fill in a spread sheet.

At present I have this code :

    string username = null;

        foreach (var user in dailyReport)
        {
             username = user.UserName;
        }

        Cell cell= worksheet.Cells["B5"];
        cell.PutValue(username);

Now obviously this just puts the last user of the collection into cell B5!
How do I collect all user.UserNames so I can place them in B5, B6, B7 and so on????

You need to put the value inside the foreach loop. The specific thing you are asking for–getting a different variable for every value in the collection–is not possible, and isn’t what you want anyway.

string column = "B"; // or whatever your column is
int row = 1; // or whatever your starting value is

foreach (var user in dailyReport)
{
    string username = user.UserName;
    string cellAddress = String.Format("{0}{1}", column, row);
    Cell cell = worksheet.Cells[cellAddress];

    cell.PutValue(username);

    row++; // make sure to increment the row, or every username goes in the same cell
}
