Try:
db_pageID = Convert.ToInt32(objDataReader["id"]);

 
Answer #2    Answered By: Randy Warren     Answered On: Jan 09

(int)objDataReader["id"];
or
int.Parse(objDataReader["id"].ToString());

 
Answer #3    Answered By: Frederick Greene     Answered On: Jan 09

Might need to check for a null value first.


if(objDataReader["id"] != System.DbNull.Value)
db_pageID = (int)objDataReader["id"];
else
db_pageID = -1;

ids = ids + Convert.ToString(ds.Tables[0].Rows[i].ItemArray["id"]) + ",";

cannot convert  string to int
