我正在向客户端发送请求到服务器进行登录，如果它被接受，主窗口将被隐藏，用户将开始处理名为user_form的表单2 ... user_form上的用户可以使用3个按钮（注销 - 退出 - 隐藏）
我希望从已经隐藏的主窗口中控制它们，
以下是我正在使用的主要代码代码......但它没有按我的意愿工作。
switch (client.LoginInfo.Limited)
{
case true:
this.Hide();
User_Form LF = new User_Form(client);
LF.AdminControlIsVisible = false;
DialogResult dr = LF.ShowDialog(this);
if (dr == System.Windows.Forms.DialogResult.Cancel)
{
//logout
}
else if (dr == System.Windows.Forms.DialogResult.OK)
{
if (client != null)
{
//hide
}
else
{
UpdateSystemMessage("No response from the server !!");
}
return;
}
break;
case false:
User_Form LF = new User_Form(client);
LF.AdminControlIsVisible = false;
DialogResult dr = LF.ShowDialog(this);
this.Visible = false;
if (dr == System.Windows.Forms.DialogResult.Cancel)
{
//logout
}
else if (dr == System.Windows.Forms.DialogResult.OK)
{
if (client != null)
{
//hide
}
else
{
UpdateSystemMessage("No response from the server !!");
}
return;
}
break;
}
任何解决方案？

如果您只是希望很好地控制在一个表单上显示的内容，从另一个表单，也许这可以帮助您...（您没有提供相关代码来举例说明使用您的项目，所以我刚刚制作通过使用保存模型数据并由两种形式共享的对象，可以改变彼此背景颜色的2种形式，而不会相互“了解”...）

编辑：
如果您想在表单上触发其他操作，您还可以在模型类上定义自己的事件并像PropertyChanged
使用您的事件的类应该只是注册一个事件处理程序，就像Form2这样更新调用计数器
edit2：更改了示例代码以显示隐藏表单并将代码从button_click处理程序重定位到单独的方法
答案 2 :(得分：0)
如果我明白你想要做什么，一个简单的方法就是你控制的形式具有公开的功能，当被叫时影响形式。然后，您需要将这些表单的实例传递给控件的表单（通常在构造函数中）。然后，您可以从控制器表单中调用这些功能，从而影响受控表单。
示例：
public class ControlledForm : Form
{
//...
//This founction will affect the form
public void DoSomething(int Params)
{
//Affect Form
}
private void SomethingEventHandler() //function that calls the new form and hides this one
{
//Give the construction this (the instance of the form) in parameter
ControllerForm newControllerForm = new ControllerForm(this);
newControllerForm.Show();
this.Hide();
}
}
public class ControllerForm : Form
{
//Constructor that receives the instance of the controlled form in parameter
public ControllerForm(ControlledForm CF)
{
_ControlledForm = CF;
InitializeComponents();
}
private ControlledForm _ControlledForm;
private void SomethingElseEventHandler() //Function that modifies the controlled form
{
//This will effectively affect the form
_ControlledForm.DoSomething(12);
}
}
如果那可以解答你的问题，我不会这样做，但这就是我遇到这个问题的原因。
