C#两个窗口之间传递数据

1 公用变量值传递

public partial class Form1 : Form  //parent form
{
public string name="";
public Form1()
{
InitializeComponent();
}
private void newBtn_Click(object sender, EventArgs e)
{
Form2 form2 =new Form2();
form2.ShowDialog(); //NOTE this! must be ShowDialog()  NOT Show()!
if (form2.DialogResult == DialogResult.OK)
{
textBox1.Text = form2.name;
form2.Close();
}
}
}

public partial class Form2 : Form // son form
{
public string name
{
set { textBox1.Text = value; }
get { return textBox1.Text; }
}
public Form2()
{
InitializeComponent();
}

private void OK_Click(object sender, EventArgs e)
{
if (textBox1.Text == "")
{
MessageBox.Show("input!");
return;
}
DialogResult = DialogResult.OK;
Close();
}
}

2 使用地址方式传递

public partial class Form1 : Form  //parent form

{
public string name="";
public Form1()
{
InitializeComponent();
}
private void newBtn_Click(object sender, EventArgs e)
{
Form2 form2 =new Form2();
form2.Owner = this;//form2的指针指向form1
form2.ShowDialog();
textBox1.Text = form2.name;
form2.Close();
}
}

public partial class Form2 : Form  //son form
{
public string name
{
set { textBox1.Text = value; }
get { return textBox1.Text; }
}
public Form2()
{
InitializeComponent();
}

private void OK_Click(object sender, EventArgs e)
{
if (textBox1.Text == "")
{
MessageBox.Show("input!");
return;
}
Form1 form1 = (Form1)this.Owner;//form2的父窗口指针赋给form1
Close();
}
}
