Hi All...
i have a situation where i have 3 different Types (classes)
comming into a controling Class to Run Different Jobs
in my main loop i want to use 1 Field to hold a instance of the Class
currently Running example below

public class controler(
{
// how to use the below process for all 3 different Type?
// this is ccalled each time a run is started in
//different threads from the service
//i want to use one field to hold the current Process
//instead of using 3 Fields and if block
private Process
public controler(int iToRun)
{
if (iToRun==1)
{
Process = new Object1() ;
}
else if (iToRun==2)
{
Process = new Object2();
}
else
{
Process = new Object3();
}
}
public int Runjob()
{
int iRet=0;
if ( (iRet=Process.Execute())<=0)
{
//error occurred
}
else
{
//success
}
}
}

Create an interface (e.g. IExecutable) with all the methods that the
different types have in common (e.g. Execute()) and make all of the
types implement that interface.
 
Analizer1,

You should have all three objects implement a shared interface, and then
cast the objects to an instance of that interface. Then, you can call the
methods on the interface.

You could do this with reflection, but that's just messy.
