从 Windows 窗体控件中按名称查找控件

Question

I have a list of my textbox names, and I want to find a control by name. How is it possible?

Answer 1

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!";
}

Answer 2

You can use:

f.Controls[name];

Where f is your form variable. That gives you the control with name name .

Answer 3

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

If Controls.Find is not found "textBox1" => error. You must add code.

If(tbx != null)

Edit:

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
If(tbx != null)
   tbx.Text = "found!";
