我有三個類,下面提供了代碼。Windows窗體不能從公共方法返回正確的值
網絡 - 添加和刪除電話,進程呼叫 電話1和電話2可以在添加到網絡時相互呼叫。
但我有問題,當我連接兩個電話到網絡,並試圖打電話給phone2,它一直在給我「接收器忙」。我試圖做一些調試,並從phone1中調用時讀取phone2的狀態,但它返回一個空字符串(當它被添加到網絡時,實際上應返回「A」)。
任何幫助將不勝感激。
-----網絡類------------------
namespace Demo
{
public partial class network : Form
{
phone1 p1 = new phone1();
phone2 p2 = new phone2();
public network()
{
InitializeComponent();
}
public Boolean numberValidator(int number)
{
Boolean exist = false;
if (comboBox2.Items.Equals(number))
{
exist = true;
}
return exist;
}
public void processCall(int rNumber)
{
if (!numberValidator(rNumber))
{
p1.TextBox1.Clear();
p1.TextBox1.Text = "Not connected";
//MessageBox.Show(p2.returnPhoenStatus());
}
else
{
p1.TextBox1.Clear();
p1.TextBox1.Text = "Call in progress";
p2.receiveCall(1);
p1.setStatus("Busy");
/*
if (p2.btnCallPressStatus())
{
p1.TextBox1.Clear();
p1.TextBox1.Text = "Call initiated";
}*/
}
}
private void button1_Click(object sender, EventArgs e)
{
if (comboBox1.SelectedIndex == 0)
{
p1.Show();
comboBox2.Items.Add(1);
p1.setStatus("A");
}
if (comboBox1.SelectedIndex == 1)
{
p2.Show();
comboBox2.Items.Add(2);
p2.setStatus("A");
}
}
}
}
----------電話1分類 - -------
namespace Demo
{
public partial class phone1 : Form
{
public phone1()
{
InitializeComponent();
}
string status;
public void setStatus(string Status)
{
status = Status;
}
public string returnStatus()
{
return status;
}
public void receiveCall(int callerNumber)
{
setStatus("Busy");
btnCall.Text = "Answer";
textBox1.Text = "Phone " + callerNumber + " Calling.";
}
public void makeCall(int number)
{
phone2 p2 = new phone2();
network net = new network();
MessageBox.Show(p2.returnStatus()); // this line not returing status of phone2
if (p2.returnStatus() == "A")
{
net.processCall(number);
}
else
{
textBox1.Text = "Receiver Busy";
}
}
public TextBox TextBox1
{
get
{
return textBox1;
}
}
private void btnCall_Click(object sender, EventArgs e)
{
string number = textBox1.Text;
int numberInt = Convert.ToInt16(number);
makeCall(numberInt);
}
string phoneNo = "";
private void btn2_Click(object sender, EventArgs e)
{
phoneNo = phoneNo + btn2.Text;
textBox1.Text = phoneNo;
}
}
}
------------- PHONE2類--------------
namespace Demo
{
public partial class phone2 : phone1
{
public phone2()
{
InitializeComponent();
}
}
}
非常感謝您的回覆。我正在尋找那樣的東西。 – 2014-11-21 11:20:58
