本文以實例詳述了C#兩個窗體之間傳遞數據的實現方法，具體的操作步驟如下：
1.建立兩個窗體，并采用公用變量值傳遞：
public partial class Form1 : Form //父窗體 { 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(); } } }public partial class Form2 : Form // 子窗體 { 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.使用地址方式傳遞
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的指針指向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的父窗體指針賦給form1 Close(); } }新聞熱點
