从父窗体和子窗体传递参数值
本文关键字:窗体 参数 | 更新日期: 2023-09-27 18:11:48
我有两个表单,一个带有'Add'按钮,它加载第二个带有两个文本框和一个提交按钮的表单。
首先,我需要一种传递文本框值给表单1(父)的方法,并使表单2关闭提交…
我该怎么做?直到现在,我已经写了这段代码,但它不工作
private void button1_Click(object sender, EventArgs e)
{
emailForm EmailF = new emailForm();
if ((EmailF.Username != null && EmailF.Password != null))
{
string user = EmailF.Username;
string pass = EmailF.Password;
}
和在emailForm.cs
private void button1_Click(object sender, EventArgs e)
{
username = username_textbox.Text;
password = username_textbox.Text;
Close();
}
public string Username
{
get { return username; }
set { this.username = value; }
}
public string Password
{
get { return password;}
set { this.password = value; }
}
你需要看看Form.ShowDialog()
。这将做你想要的,当用户关闭对话框窗口时,你可以确保他们点击"确定"(或其他),然后从表单中获取值。
public void ShowMyDialogBox()
{
Form2 testDialog = new Form2();
// Show testDialog as a modal dialog and determine if DialogResult = OK.
if (testDialog.ShowDialog(this) == DialogResult.OK)
{
// Read the contents of testDialog's TextBox.
this.txtResult.Text = testDialog.TextBox1.Text;
}
else
{
this.txtResult.Text = "Cancelled";
}
testDialog.Dispose();
}
