Question

I have to add all the Id from the dataset that has Status value same as “Active” to the int array PromotionID. How is that possible. What am i missing?

int[] promotionID;
foreach (DataRow dr in ds.Tables[0].Rows[i]["Status"].ToString() == "Active")
{

    promotionID = new int[] { Convert.ToInt32(dr["Id"]) };
}

The error is:

foreach statement cannot operate on variables of type ‘bool’ because ‘bool’ does not contain a public definition for ‘GetEnumerator’

You’ll want something like this:

List<int> promotionLst = new List<int>();
foreach (DataRow dr in ds.Tables[0].Rows) {
    if (dr["Status"].ToString() == "Active") {
        promotionLst.Add(Convert.ToInt32(dr["Id"]));
    }
}
int[] promotion = promotionLst.ToArray();
