you are trying to convert reader into a string not a string collection by using ToString(); then obviously it will throw you an error. Try type casting the reader yar....

Amazing! Why would you even expect something like that? And what would be the purpose? A string is a string, not a collection of strings.

Datareader is a "stream-based" data object and the data can be access only sequentially. So, there is no way to directly assign the data reader to a string collection.

Below is one of the ways to accomplish what you wish -

C#

if (reader.HasRows)
{
    while (reader.Read())
    {
         dodetails.Add(reader.GetString(column_number))
    }
}

HTH!

Solution 2

C#

StringCollection dodetails = new StringCollection();
//Checking whether reader contains any value oe not.
if (reader.HasRows)
  {
      int i=0;
           while (reader.Read())
           {
               dodetails.Add(reader.GetValue(i));
              //Storing all Datarader value into collection
           }
   }
