frmPlaceOrder 是我的 form1。我需要将此表单中的 firstName、lastname 和 Address 传递给将执行其他功能的第二个。我不知道该怎么做。
namespace Lab1_OrderCake
{
public partial class frmPlaceOrder : Form
{
public static CustomerInformation customer;
public static Address address;
public frmPlaceOrder()
{
InitializeComponent();
customer = new CustomerInformation(txtFName.Text, txtLName.Text);
address = new Address(txtAddress.Text, txtCity.Text, txtPC.Text, txtProvince.Text);
}
private void btnPlaceOrder_Click(object sender, EventArgs e)
{
DialogResult dlgMsg;
if (txtFName.Text == "")
{
MessageBox.Show("Please enter first name", "Data Missing");
txtFName.Focus();
return;
}
if (txtLName.Text == "")
{
MessageBox.Show("Please enter Last name", "Data Missing");
txtLName.Focus();
return;
}
else
{
frmCakeOrder newCust = new frmCakeOrder();
this.Hide();
newCust.ShowDialog();
this.Close();
}
}
}
}
第二种形式；填写完第一个后，需要从 form1 中获取值并将其与第二个表单中的其他值（frmCakeOrder 值）一起显示。当我单击它时，它需要在 View 和 Order 事件中看到。
这是第二种形式：
namespace Lab1_OrderCake
{
public partial class frmCakeOrder : Form
{
Order cakeOrder;
public List<Cake> cakeList;
public frmCakeOrder()
{
InitializeComponent();
cmbTraditionalCake.SelectedIndex = 0;
cakeOrder = new Order();
gbCustomCake.Visible = false;
this.Size = new Size(700,360);
cakeList = new List<Cake>();
}
private void bttnOrder_Click(object sender, EventArgs e)
{
DialogResult dlgMsg;
dlgMsg = MessageBox.Show(cakeOrder.ToString(), "Confirm Order", MessageBoxButtons.YesNo, MessageBoxIcon.Information);
if (dlgMsg == DialogResult.Yes)
{
MessageBox.Show(cakeOrder.PrintConfirmation());
}
else
{
MessageBox.Show ("The order has not been placed");
}
bttnReset.Focus();
cakeOrder.ClearCart();
}
private void radCustom_CheckedChanged(object sender, EventArgs e)
{
if (radCustom.Checked)
{
cmbTraditionalCake.Enabled = false;
gbCustomCake.Visible = true;
}
else
{
cmbTraditionalCake.Enabled = true;
gbCustomCake.Visible = false;
}
}
private void btnView_Click(object sender, EventArgs e)
{
DialogResult dlgMsg;
cakeOrder.NumOfCakes=1;
dlgMsg = MessageBox.Show(cakeOrder.ToString(), "Your order: ", MessageBoxButtons.YesNo , MessageBoxIcon.Information);
if (dlgMsg == DialogResult.No)
{
cakeOrder.ClearCart();
MessageBox.Show("Please enter and confirm your order!");
}
private void btnAdd_Click(object sender, EventArgs e)
{
if (radCustom.Checked)
{
string flavour, occasion;
flavour = occasion = "";
int layers;
//for flavor
if (radBanana.Checked)
flavour = "Banana";
else if (radChocolate.Checked)
flavour = "Chocolate";
else if (radVanilla.Checked)
flavour = "Vanilla";
if (radTier2.Checked)
layers = 2;
else if (radTier3.Checked)
layers = 3;
else
layers = 1;
if (radGraduation.Checked)
occasion = radGraduation.Text.TrimStart(new char[] { '&' });
else if (radWedding.Checked)
occasion = radWedding.Text.TrimStart(new char[] { '&' });
else occasion = radAnniversary.Text.TrimStart(new char[] { '&' });
cakeOrder.AddCake(new Custom(flavour, occasion, layers));
}
else
{
cakeOrder.AddCake(new Traditional(cmbTraditionalCake.SelectedItem.ToString()));
}
cakeList.Add(cakeOrder);
}
}
}
有很多方法可以做到这一点。试试这个方法。
private void btnPlaceOrder_Click(object sender, EventArgs e) {
string fname = textBox1.Text;
frmCakeOrder frm = new frmCakeOrder(textBox1.Text);
frm.Show();
}
在 frmCakeOrder 中，
public frmCakeOrder(string fname) {
InitializeComponent();
textBox1.Text = fname;
}
