推荐答案
灰烬,
欢迎使用C#.首先,您的应用程序似乎是WinForms,因此您在错误的论坛上发布了内容,因为在此论坛中我们讨论的是WPF,它是不同的UI堆栈.
Welcome to C#. First off your application seems to be WinForms so you posted in the wrong forum as in this forum we discuss WPF which is a different UI stack.
但是要回答您的问题:在单击事件中使用的方法不起作用,因为您正在创建常规表单并为其分配名称,该名称可以是任何形式,并且仍然只是您拥有的常规表单打开并给予不同的 姓名.您的申请书中有什么表格?
But to answer your question: the approach you are using in the click event is not working as you are creating a general form and assigning it a name, the name can be anything and it will still just be a general form you have opened and given a different name. What forms do you have in your application?
假设您有一个名为MainForm的表单,那么您需要使用以下代码打开它:
Lets say you have a form called MainForm, then you need to open it using this code:
MainForm frm = new MainForm();
frm.Show();
如果要基于字符串名称打开表单,请使用以下代码(其中 WindowsFormsApplication2 是您的应用程序的名称)
If you want to open a form based on a string name use this code (where WindowsFormsApplication2 is the name of your application)
Form frm = (Form)(Assembly.GetExecutingAssembly().CreateInstance("WindowsFormsApplication2.MainForm"));
frm.Show();
在上面的示例中,我们使用反射,因此必须使用以下命令添加它:
In the above example we use reflection so you must add this using:
using System.Reflection;
我希望这会有所帮助.
