How to change the text of the multiple asp:label using for loop in C# ASP.NET

I want to change the asp label multiple times.

Here is the asp.net code

<asp:Label ID="lbl_Text1" runat="server" Text="">
<asp:Label ID="lbl_Text2" runat="server" Text="">
<asp:Label ID="lbl_Text3" runat="server" Text="">
<asp:Label ID="lbl_Text4" runat="server" Text="">

Instead of using this:

C# Code

lbl_Text1.Text = "hello";
lbl_Text2.Text = "hello";
lbl_Text3.Text = "hello";
lbl_Text4.Text = "hello";

I tried to use for loop

for (int i = 1; i <= 4; i++)
{
    lbl_Text[i].Text = "hello";
}

And I get this error.....

cannot apply indexing with [] to an expression of type 'system.web.ui.webcontrols.label'

Is there anyone can help me on that?

You can try by using FindControl

for(int i = 1; i <= 4; i++){
  var label = ((Label)FindControl("lbl_Text" + i));
  if(label != null){
     label.Text = "hello";
  }
}
