Creating multiple RequiredFieldValidators in Code Behind

I want to be able to create RequiredFieldValidators in code behind. The controls (to be validated) are created in the code behind which reads the control details from a database - so there could be any number of controls on the page.
So, starting with basics, let's assume that I have 1 DropDownList (myDDL1) on my page. The code would be as follows:

RequiredFieldValidator myRFV = new RequiredFieldValidator(); myRFV.ControlToValidate = "myDDL1"; myRFV.ErrorMessage = "you must select a value!"; form1.Controls.Add(myRFV);

When there is more than 1 control (eg myDDL1 and myDDL2), then I need to create a different RequiredFieldValidator for each control to be validated. The following code doesn't work - it is just to give a simplified example of what I am trying to achieve. The problem is that I need to be able to dynamically name the requiredFieldValidator - myRFV

Int32 myCount = 1; RequiredFieldValidator myRFV + myCount = new RequiredFieldValidator(); // myRFV + myCount does not work!!! myRFV + myCount.ControlToValidate = "myDDL1"; myRFV + myCount.ErrorMessage = "you must select a value!"; form1.Controls.Add(myRFV + myCount);     myCount = 2; RequiredFieldValidator myRFV + myCount = new RequiredFieldValidator(); myRFV + myCount.ControlToValidate = "myDDL2"; myRFV + myCount.ErrorMessage = "you must select a value!"; form1.Controls.Add(myRFV + myCount);

So, first the RFV control name would be myRFV1 and the second RFV control would be myRFV2.
But C# wont let me create the RFV instances in this way. If I use the same RFV name (myRFV), and only change the .ControlToValidate, then only the second drop down list will get validated.
