.net SqlDataReader VB C＃

Question

I have this statement:

if (sqlClass.Reader != null && sqlClass.Reader.HasRows)
    {
        do
        {
            data = sqlClass.Reader.GetString(0); //error line System.InvalidOperationException {"Invalid attempt to read when no data is present."}
        } while (sqlClass.Reader.Read());
    }

the object sqlClass.Reader is of type System.Data.SqlClient.SqlDataReader

In C# it gives me an InvalidOperationException but in VB it worked fine, what would the reason be and how do I solve this?

Answer 1

Something like this:

if (null != sqlClass.Reader)
{
    while (sqlClass.Reader.Read())
    {
        data = sqlClass.Reader.GetString(0);
    }
}
