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.
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();
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开发者_运维百科
nextForm1.ShowDialog();
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.
Thoughts? Thanks!
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();
Thanks!
Get the type of the form: Type.GetType("name.space." + formname)
, so if your class is name.space.CloudAccessForm
, then pass in CloudAccessForm
as formname, and it will give you the type. Then you can instantiate it with Activator.CreateInstance(type)
. Then cast it to a Form
, and show it.
