请尝试以下

最初为所有三个文本框分配默认颜色为浅蓝色

接下来创建两个事件 textBox1_Enter / textBox1_Leave 如下

Please try the following
Initially assign the default color as Light blue for All three text box
next create two events textBox1_Enter/textBox1_Leave as follows

private void textBox1_Enter(object sender, EventArgs e)
       {
           textBox1.BackColor = Color.White;
       }

       private void textBox1_Leave(object sender, EventArgs e)
       {
           textBox1.BackColor = Color.LightBlue;
       }

用于文本框焦点更改事件

use this for textbox focus change event

private void textBox1_Validating(object sender, CancelEventArgs e)
       {
           textBox1.BackColor = System.Drawing.Color.Red;
       }
       private void textBox1_Enter(object sender, EventArgs e)
       {
           textBox1.BackColor = System.Drawing.Color.Yellow;
       }
