在我的申请中,我打开新表格:
private void button1_Click(object sender, EventArgs e)
{
Form2 = new Form2 ("bla bla");
Form2 .ShowDialog();
}
这是我打开的表格,想要传回参数:
public partial class Form2: Form
{
public Form2 (string file)
{
InitializeComponent();
}
}

您可以定义要在Form2中返回的公共变量,并在Form1中访问它们:
public partial class Form2: Form
{
public int x; //can be private too
public string y; //can be private too
public Form2 (string file)
{
InitializeComponent();
}
//define some function which changes defined global values
}
在Form1中:
Form2 form2 = new Form2("bla bla");
form2.ShowDialog();
MessageBox.Show(form2.x.ToString());
MessageBox.Show(form2.y);
