Question

I am trying to do something like this:

for (int i = 1; i < nCounter ; i++)
{
    string dvName = "dv" + i.ToString();
    System.Windows.Forms.DataGridView dvName = new DataGridView();
    // other operations will go here..
}

As you can guess, what I am trying to do is at i == 1, create a DataGridView with name dv1, and at i == 2, create a DataGridView with name dv2, but I can’t.

Visual studio squiggles saying “a local variable named dvName is already delared in this scope” I also tried the following:

for (int i = 1; i <nCounter ; i++)
{
    System.Windows.Forms.DataGridView dv & i = new DataGridView();
    // other operations will go here..
}

But VS squiggles again, I hope you understood what I am trying to accomplish. Can anyone suggest how can I do this?

So your are trying to create the variable name dynamically? That’s not possible. Why not use an Array or a List (or even a Dictionary)? Or do you want to just set the name of the control?

var list = new List<DataGridView>();

for (int i = 1; i <nCounter ; i++)
{
    System.Windows.Forms.DataGridView dvName = new DataGridView();
    dvName.Name = "dv" + i.ToString();
    list.Add(dvName);
    // other operations will go here..
}

foreach (var dv in list)
{    
    ...do something... 
}

DataGridView secondDv = list.Single(dv=>dv.Name == "dv2");
secondDv.DoSomething()

Not clear want you want to do…
