SqlDataReader.GetInt32 problem

[devi]

I'm using this method to populate a comboBox directly from the db but when i execute i get this error: InvalidCastException was unhandled.Specified cast is not valid.

here is the method.
private void buildcboAuthors()
{
string strQuery = "Select k.Name as State_Name from States k where k.Name_ID=19 or k.Name_ID=17 or k.Name_ID=20 or k.Name_ID=11 or k.Komuna_ID=04";

SqlCommand cmd = new SqlCommand(strQuery, sqlConn);

this.sqlConn.Open();
SqlDataReader dtRead = cmd.ExecuteReader();
ArrayList Komuna = new ArrayList();
while (dtRead.Read())
{
Komuna.Add(new AddValue(dtRead.GetString(1), dtRead.GetInt32(0)));

}
dtRead.Close();
this.sqlConn.Close();
this.cmbStates.DataSource = Komuna;
this.cmbStates.DisplayMember = "View";
this.cmbStates.ValueMember = "Value";

}
what am I doing wrong ???

can anyone help me

Trying adding a .ToString() to the end of the GetInt32() Method

     Komuna.Add(new AddValue(dtRead.GetString(1),
                dtRead.GetInt32(0).ToString()));
