Using user controls having his name on a string

i have a problem, the functionality I'm looking for exactly is:

I have a grid and datagrid, according to the line to select the datagrid there will be to introduce a user control or other user controls are different pictures I've made polylinesegments, bezier cuadratic ... to introduce the call will name, which build on a string, but I have no way to call it correctly.

This is what I do and it works by putting the full name:

d48.Children.Add(new tratsPintados.end148());

But put the string, tells me not find the path in the 开发者_StackOverflow社区project, what I want is to find the path inside the string.

d48.Children.Add(new thestring());

Any ideas?

If you need to instantiate some class based on its name (without real reference), you will need to use Reflection. Maybe you can do some lookup by name for the class you need, and then use Activator.CreateInstance to call its default constructor. I hope this is what you want, the question text is quite confusing to me.

using System.Reflection;

public object GetObjectFromString()
{

string objectName = "WpfApplication1.uc1";

            Type newType = Type.GetType(objectName, true, true);

            object o = Activator.CreateInstance(newType);

// do what you want with the 'o' variable, maybe cast it to the type you want.
}
