Use Control.ControlCollection.Find.
TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";
EDIT for asker:
Control tbxs = this.Controls.Find(txtbox_and_message[0,0], true);
if (tbxs != null && tbxs.Length > 0)
{
tbxs[0].Text = "Found!";
}

Getting this error.. .net framework 2.0.. 'System.Array' does not contain a definition for 'FirstOrDefault' and no extension method 'FirstOrDefault' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)

Are you dynamically adding textbox into your form during runtime? If this is the case, you can assign a unique name to each textbox, and use controls.find to find the textbox with its unique name.

No i am not adding dynamically.. I have already list of textboxes .. And i have stored names of all taxboxes in one array. From that array i am fetching names and than finding textboxes and than want to fetch text from the specific textbox ..

You can use:
f.Controls[name];
Where f is your form variable. That gives you the control with name name.

Note that this doesn't work if the control is nested (you'll only find controls present at that level in the control hierarchy).
