本文以实例详述了C#两个窗体之间传递数据的实现方法，具体的操作步骤如下：
1.建立两个窗体，并采用公用变量值传递：
public partial class Form1 : Form //父窗体
{
public string name="";
public Form1()
{
InitializeComponent();
}
private void newBtn_Click(object sender, EventArgs e)
{
Form2 form2 =new Form2();
form2.ShowDialog();
if (form2.DialogResult == DialogResult.OK)
{
textBox1.Text = form2.name;
form2.Close();
}
}
}
</div>
public partial class Form2 : Form // 子窗体
{
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();
}
}
</div>
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();
}
}
</div>
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的父窗体指针赋给form1
Close();
}
}
</div>
</div>
