changing if statement during runtime when new control is added

[hoadiem]

this is for excel .

I have a form with 2 combobox and 1 textbox

combo 1 : user can select a column ; let say column A
combo 2 : user can select an operator ; let say = (equal)
textbox : user can enter value ; let say 2

so my code is like

if (column A == tb.text)
{
    execute code here
}

but the problem i have is during run time i allow user to add more controls to the form

if ((column A == tb.text) && (column B == tb2.text)) && //may be more if user add
{
   execute code here 
}

how do i handle this 'cause i have no idea how many will the user add to it, and the code should change when user add new control to it.

if possible , please give me sample code

much thanks.

Hey hoadiem, i assumed number of items in comboBox1 and number of textBoxes are equal in your form... You can use like this,

void Check_Click(object sender, EventArgs e)
{
    bool flag = true;
 
    var textBoxes = from textBox in this.Controls.OfType<TextBox>()
                            select textBox;
 
    int i = 0;
 
    foreach (var item in textBoxes)
    {
        if (!comboBox1.Items[i].Equals(item.Text))
        {
            flag = false;
            break;
        }
 
        i++;
    }
 
    if (flag)
    {
        MessageBox.Show("Equal");
    }
    else
    {
        MessageBox.Show("Not Equal");
    }
}
