how to open second form from first form in c# ?

推荐答案

其中有一个小技巧，因此许多初学者在阅读常规MSDN帮助时会感到困惑.页面:
http://msdn.microsoft.com/en-us/library/system. windows.forms.form.aspx [ ^ ].

原因是:即使可以关闭表单，也没有打开表单"这样的概念.您只需使用其构造函数创建一个表单，然后调用方法Show或ShowDialog来显示模拟的模态对话框行为.但是，我强烈建议使用关系所有权表单/所有者表单，因此最好保留主表单和所有其他非模式表单的所有者，请使用AddOwnedForm，请参见:
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.addownedform.aspx [ ^ ].

就这样.

是的，最好不要使用MDI，不要用这种丑陋的设计风格来折磨自己并吓跑用户.如果您有任何疑问，我会解释.

There is a little trick in it, so many beginners get confused when reading a usual MSDN help page:
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.aspx[^].

The reason is: there is no such concept as "open a form", even though a form can be closed. You simply create a form with its constructor and later call the method Show or ShowDialog to show imitating modal dialog behavior. However, I strongly recommend to use the relationship owned form / owner form, so better keep the main form and owner of all other non-modal forms, use AddOwnedForm, please see:
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.addownedform.aspx[^].

That''s it.

And yes, better never use MDI, don''t torture yourself and scare off your users with this ugly design style. If you have questions on it, I''ll explain.

在Visual Studio中创建一个表单，然后指定要打开的表单的名称，即"openedform"

单击按钮或使用以下代码即可:

Hi,

Create a form in your Visual Studio and then specify name of your to be open form, i.e ''openedform''

Use code below at button click or whatever:

openedform frm = new openedform();
frm.Show(); // or frm.ShowDialog() to open a form as dialog

希望有帮助.

Hope this help.

您好，
当您创建应用程序时，它会提供1个来自.只需右键单击该项目并添加新表单.
然后在Form1类中为Form2创建一个对象.
Form2 objForm2 =新的Form2();
objform2.Show();


此外，如果要在Form1的Form2中进行任何更改，最好将这种形式的当前对象发送到Form2，方法是

Form2 objForm2 =新的Form2(this);
objform2.Show();

为Form2创建一个副本构造函数.

Hi,
when you create application it is provided with 1 from. Just Right click on the project and add new form.
then create a object for the Form2 in Form1 Class.
Form2 objForm2 = new Form2();
objform2.Show();


Further, if you want to change any thing in Form1 form Form2, better to send the current object of form1 to Form2, this way

Form2 objForm2 = new Form2(this);
objform2.Show();

create a copy constructor for the Form2.
