Question

I am not following how to initialize a class constructor which accepts the names of DropDowns in an array as below:

public FillDropDowns(DropDownList[] DropDownNameArray)
{
    PopulateDropDown(DropDownNameArray);
}

I have a class named FillDropDowns with a method PopulateDropDown.

From my Web Form, I want to create an instance of this class and pass the names of DropDowns.

Answer 1

DropDownList[] parameter = new DropDownList[1]; // create an array of DropDownList 

parameter[0] = DropDownList1; // add DropDownList1 to the array (the reference to the drop down list you want include)

var yourClass = new FillDropDowns(parameter); // make a new instance of the class by passing the array via the constructor
