fetch data from IBM DB2 using C#
 
Hi all,
We have a requirment to develop windows based application using C# 2.0 and IBM DB2.
For connecting to DB2, I am refering IBM.Data.DB2.dll in my application. During run time it raise exception in connection declaration.
I have DB2 Client in my local machine, and it is connecting to server also. But through appliaction it raise exception.
I got IBM.Data.DB2.dll from server machine. I refered this dll into my application. I am attaching my code snippet here.

DB2Connection Con = new DB2Connection("Server=myserver; Database=dbname; UID=Db2admin; PWD=password;");
DB2Command cmd = new DB2Command();
cmd.CommandText = "Select * from Reports";
cmd.Connection = Con;
cmd.CommandTimeout = 60;
Con.Open();
DB2DataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection) ;

Exception is raising in connection string line itself. Please tell me why this exception is raising.
Followig are the Exception message.
