Question

I have a datatable customerTbl and I step through the rows

foreach (DataRow row in customerTbl.Rows)
{
         string CustomerID = row["Customer ID"].ToString();
}

However, the column Customer ID returns byte[]. How can I convert this to a string (CustomerID)?

I tried something like

string CustomerID = Convert.ToBase64String(row["Customer ID"]);

but it obviously doesn’t work

Thanks in advance

Depending on the encoding of the bytes, you’d need the correct Encoding object to perform the conversion. Assuming it is ASCII, you can do this:

string customerID = Encoding.ASCII.GetString((byte[])row["Customer ID"]);

If in a different encoding (UTF8, UTF16, etc.), use the appropriate one.
