您好我刚接触到C＃的东西我刚刚学习。
所以我的问题是我想将listBox1项Form1从Form2发送到listBox2 listBox1，并显示Form2的项目在public partial class TopliNapitki : Form
{
public TopliNapitki()
{
InitializeComponent();
}
int pomozno=0;
decimal cena = 0;
decimal kava = 1.10m;
decimal cap = 1.30m;
decimal bKava = 1.60m;
decimal kavaM = 1.30m;
decimal caj = 1.30m;
decimal kakav = 1.70m;
decimal vCokolada = 1.80m;
decimal lKava = 2.50m;

}
}
}
。
Im来自斯洛文尼亚，因此更新了表格名称和其他条目
这是第一个名为：
的表格 public partial class Racun : Form
{
public Racun()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
var form1 = new Form1();
this.Close();
form1.Show();
}
public string _textBox
{
set { textBox1.Text = value; }
}
public string _listBox
{
set { listBox1.Items.Add(value); }
}
}
第二个表格：
public string _listBox1
{
get { return listBox1.Text; }
}
private void button10_Click(object sender, EventArgs e)
{
var form1 = new Racun();
form1.Show();
form1._listBox = _listBox1;
this.Close();
form1.Show();
}
}
我有这个设置用于发送listBox的数据，但它在Form1上不起作用：
public string _listBox
{
set { listBox1.Items.Add(value); }
}
Form2中有这个：
{{1}}
答案 0 :(得分：2)
传递构造函数中的值：
string _listValue;
public Racun(string listValue)
{
InitializeComponent();
_listValue = listValue;
}
它将被称为：
private void button1_Click(object sender, EventArgs e)
{
var form1 = new Rancun(_listBox);
this.Close();
form1.Show();
}
我还认为您在尝试从列表框中取出所选项目时遇到错误。它应该像这样调用：
get { return listBox1.SelectedValue.ToString(); }
