Textboxes do not have highlight formatting, the best you can do is Select text.

您可以使用以下代码段，该代码段通过单击以下按钮从TextBox2内的textBox1中查找文本:

You may use this snippet, which finds a text from textBox1 inside TextBox2 by clicking on a button:

private void button1_Click(object sender, EventArgs e)
{
   int idx = textBox2.Text.IndexOf(TextBox1.Text);
   if (idx >= 0)
   {
      textBox2.SelectionStart = idx;
      textBox2.SelectionLength = TextBox1.Text.Length;
      textBox2.Focus();
   }
}
