本次示例效果如下：
Form1为父窗体(包含textBox1、button1)
Form2为子窗体(包含textBox2、button2)
父窗体给子窗体传值
==================
1.点击Form1的button1 打开Form2
父窗体给子窗体传值 可以调用重载子窗体的构造函数 直接传入相关数值
|
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Form2 frm2 = new Form2(this.textBox1.Text);
frm2.Show();
}
}
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
public Form2(string strTextBox1Text)
{
InitializeComponent();
this.textBox2.Text = strTextBox1Text;
}
} |
2.点击Form1的button1 打开Form2
并调用子窗体Form2的公开属性或方法 将Form1的textBox1的值设置给Form2的textBox2
|
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Form2 frm2 = new Form2();
frm2.TextBox2Text = this.textBox1.Text;
frm2.Show();
}
}
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
public string TextBox2Text
{
set { this.textBox2.Text = value; }
get { return this.textBox2.Text; }
}
} |
