我想你好我明白你的问题。因此，您不仅要打开一个新表单，还要更改第二个表单上文本框的背景颜色。所以这意味着你想在第一个表单中调用第二个表单事件。你可以这样做。

Hi there, I think I understood your problem. So you not only want to open a new form, but you want to change the backcolor of the textbox on the 2nd form. So it means you want to call the 2nd form event within the first form. You can do it as below.

//-----------------------------Form1----------------
 //Create form1 and add 1 textbox and 2 buttons on it
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        Form2 frm2 = new Form2();
        
        private void button1_Click(object sender, EventArgs e)
        {
           frm2.Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            textBox1.BackColor = Color.Red;
            frm2.TextboxBackColor = Color.Red;
            frm2.button1_Click(sender, e);
        }
    }


//-----------------------------Form2----------------

//Create form2 and add one textbox and a button on it
    public partial class Form2 : Form
    {
        //Property to get the textbox back color from form1
        public Color TextboxBackColor { get; set; }
        public Form2()
        {
            InitializeComponent();
            //textBox1.BackColor = TextboxBackColor;
        }

        internal void button1_Click(object sender, EventArgs e)
        {
            textBox1.BackColor = TextboxBackColor;
        }
    }
