Passing a DataReader

Hello,
I am passing a DataReader object to a calling methid but when I try to get the data out of DataReader in the calling methid I get the error that data does not exist
I know that the connection has to be open and I did make sure that it is. I can go through the records in the methid that creates the reader, but not in the method that calls it.
Here is my code:

Public Class Conn
{

public SqlDataReader GetData(string strStatement)
{
SqlDataReader dr = null;

try
{

SqlCommand cmd = new SqlCommand(strStatement, cn1);
cn1.Open();

dr = cmd.ExecuteReader();
while(dr.Read())
{
Console.WriteLine(dr.GetString(0));//this works fine!

}
}
catch (System.Exception e)
{
System.Console.WriteLine(e.Message.ToString());
return null;

}
return dr;
}

Now this is the calling procedure:

string strPropSelect="SELECT * FROM TMYTABLE";
dr = conn.GetData(strPropSelect);
if (!dr.HasRows)//this is fine
{
System.Console.WriteLine("ERROR: Failed to load property data");
return;
}

//but it errors out below
System.Console.WriteLine(dr.GetString(0));


Thanks for any help!!!
