我有两种形式:Form1和Form2。 Form1有button1,Form2有button2。 当项目运行时,将显示Form1,然后单击button1,然后显示Form2并隐藏form1。如果我单击button2,则Form1可见,Form2关闭!
Form1中:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
this.Hide();
Form2 fo = new Form2();
fo.Visible = true;
}
}
窗体2:
公共部分类Form2:表格 { 公共Form2() { 的InitializeComponent(); }
private void button1_Click(object sender, EventArgs e)
{
Form1 f1 = new Form1();
f1.Visible = true;
this.Close();
}
}

void Button1_Click(...)
{
Form2 f2=new Form2(form1);
f2.ShowDialog();
form2.Hide();
}
void Button2_Click(...)
{
this.Hide();
form1.Show();
}

假设Form1是传递给program.cs中的Application.Run()的“启动表单”:
public partial class Form1 : Form
{
private void button1_Click(object sender, EventArgs e)
{
this.Hide();
foreach (Form frm in Application.OpenForms)
{
if (frm is Form2)
{
frm.Show();
return;
}
}
Form2 f2 = new Form2();
f2.Show();
}
}
使用:
public partial class Form2 : Form
{
private void button1_Click(object sender, EventArgs e)
{
this.Hide();
foreach (Form frm in Application.OpenForms)
{
if (frm is Form1)
{
frm.Show();
return;
}
}
}
}
