c#窗體傳值
1. 父窗體向子窗體傳值
父窗體Form1程式
//使其成為主窗體Form1的一個屬性,
private string text;
public string Text
{
get { return text; }
set { text = value; }
}
private void button1_Click(object sender, EventArgs e)
{
text = "rfeg";
Form2 fmChild = new Form2();
fmChild.ShowDialog(this);
}
子窗體Form2程式
//Form1向Form2傳值
private void Form2_Load(object sender, EventArgs e)
{
Form1 fmMain;
fmMain = (Form1)this.Owner;
textBox1.Text = fmMain.Text;
}
2. 子窗體向父窗體傳值
父窗體Form1程式
//使其成為主窗體Form1的一個屬性,
private void button1_Click(object sender, EventArgs e)
{
text = "rfeg";
Form2 fmChild = new Form2();
fmChild.ShowDialog(this);
if (fmChild.DialogResult == DialogResult.OK)
{
textBox1.Text = fmChild.Path;
}
else if (fmChild.DialogResult == DialogResult.Cancel)
{
textBox1.Text = "form was canceled";
}
fmChild.Close();
}
子窗體Form2程式
public string Path
{
get { return 瀏覽框.Text; }
set { 瀏覽框.Text = value; }
}
private void button2_Click(object sender, EventArgs e)
{
if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
{
瀏覽框.Text = folderBrowserDialog1.SelectedPath;
}
}
