问题描述
我的构造函数有问题.我将其设置如下:
I have a problem with my constructor. I got it set up like this:
Form1:
private void button10_Click(object sender, EventArgs e)
{
var form2 = new Form2(listBox1);
form2.Show();
this.Hide();
}
Form2:
public Form2(ListBox listBox)
{
InitializeComponent();
listBox1.Items=listBox.Items;
}
我只想将数据从Form1上的listBox发送到Form2 listBox,但这给了我这个错误:
I just want to send my data from listBox on the Form1 to my Form2 listBox but it's giving me this error:
推荐答案
您可以使用Sampath的答案,这是完全正确的.但是出于可读性和较短的代码的目的,您可以使用 ListBox.ObjectCollection.AddRange方法 :
You could use the answer from Sampath, which is completely correct. But for readability and shorter code, you can use the ListBox.ObjectCollection.AddRange Method:
public Form2(ListBox listBox)
{
InitializeComponent();
listBox1.Items.AddRange(listBox.Items);
}
