Find control by name in Windows Forms

Finding controls by name in Windows forms is a convenient way to access specific elements in a form. This is especially useful when dealing with a large number of controls or automation tasks.

Solution:

To find a control by name, use the Control.ControlCollection.Find method. This method takes a string parameter that indicates the name of the control to be searched.

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;

In this example, we search for a control named "textBox1" in the Controls collection of the current form. If the control is found, it is converted to a TextBox object and assigned to the tbx variable.

Other usage:

Find method can also be used in control arrays:

Control[] tbxs = this.Controls.Find(txtbox_and_message[0,0], true);

This allows you to find multiple controls by name and perform actions on them.

Notice:

Make sure that the control name you specify is unique in the form. Otherwise, Find may return any control with the specified name.
