using for on objects and their properties?

i'm writing a program in C# , which contains a dozen toolstrips and each one contains a toolstriplabel :

toolstriplabel1 toolstriplabel2 toolstriplabel3 . . . toolstriplabel11 toolstriplabel12

i want to change each ones text with a "for" loop , how can i do that?? i can use "if" with other variables to meet this , but i want to avoid the dozen "if"s i have to write. How Can i use a "for" loop with toolstriplabel's , text property? i tried using this code , it doesn't work :

    for (int r = 0; r < NumGraphs; r++)
    { 
       toolStripLabel+"i".text=...
    }

What about using LINQ on collection of controls?

var labels = this.Controls.Cast<Control>()
                 .OfType<ToolStripLabel>()
                 .Where(l => l.Name.Contains("toolstriplabel"));

Then you can simply loop through them with a foreach loop.

foreach (var label in labels) { label.Text = ""; }

You can simply try something like this,

        foreach (Control ctr in this.Controls)
        {
            if (ctr is ToolStripLabel)
            {
              // ur code
            }
        }

Not familiar with C# but You can create an array of these toolStrips. In for loop, set the text property of the ith element in the array at ith iteration.

  for (int i = 0; i < NumGraphs; i++) { 
         toolStripLabel[i].text="YOUR TEXT";
  }
