textbox1.Text 无法从另一个表单复制 textbox2.Text 值[关闭]

Question

下面是我的代码

private void btnCptKb5_Click(object sender, EventArgs e)
{ 
   Form1 form1 = new Form1();
   textbox1.text = form1.textbox1.text;
}

为什么我不能复制form1文本框的值？

Answer 1

• 你没有改变Textbox2.Text的值

• 您正在创建一个全新的表单实例，并尝试访问该表单的文本框值。即使您的代码有效，它也始终为空。
