使用一个字符串值来创建新的表单对象 [英] Use value of a string to create new form object

问题描述

我有一个推出的主要形式，然后就可以去任何我所创建的其他形式。但踢球的是，我写了一个类，我调用返回的形式去的名称的字符串。

I have a main form that is launched and then it can go to any of the other forms I have created. But the kicker is that I have written a class that I call that returns a string with the name of the form to go to.

目前我没有这方面的工作所以我从形式要形成这样的（静态链接编写代码）：

Currently I don't have this working so I am going from form to form like this (statically written linking code):

this.Hide();
CloudAccess nextForm1 = new CloudAccess(); 
   //Where CloudAccess is the class of the next form.
nextForm1.ShowDialog();

我要的是这样的：

What I want is something like this:

FormController pick = new FormController();
   //Where FormController is the Class I create an object of and ask what's next
string next = pick.whereToGo(); //lets say it returns "CloudAccess"
this.Hide();
next nextForm1 = new next(); //next is desired to be the contents of the string
nextForm1.ShowDialog();

的问题是，我不知道如何使用返回的字符串，使新的对象，用它。我一直在寻找的调用和思考的话题像这样的：使用字符串值创建新实例
，而我是新的C＃，我不知道如何适用于这种情况。

The problem is that I don't know how to use the returned string to make the new object and use it. I've been looking at Invoke and Reflection topics like this one: Use string value to create new instance But I'm new to C# and I'm not sure how to apply that to this scenario.

的思考？ ！谢谢

推荐答案

下面是从工作的代码是什么fejejosco说：

Here's the working code from what fejejosco said:

string asdf = "CloudAccess";
Type CAType = Type.GetType("namespace." + asdf);
Form nextForm2 = (Form)Activator.CreateInstance(CAType);
nextForm2.ShowDialog();

谢谢！
