String2DataType function

[mariano_donati]

Hi,

I want to implement a function that take a given a string and return, if it exists, a data type so it can be used for casting later. Here's an example of what I'd like to accomplish:

(String2DataType("System.Windows.Forms.Form"))object;
obj.Show();

Is there such a function in c# or at least a way to implement that?

Regards.

Casting is a compile time process, not runtime. If you need to dynamically create an object of an unknown type at runtime you will need to look into reflection and you will also need an interface so that you can use the object in your code.

I have no idea what you are trying to achieve.

I think what you need is to Use Activator.CreateInstance to create an object from a string:

So you have the name of the type and you want to cast and object to that type.

Somebody have had a similar problem over at stack overflow check it out, it might help you:

Thank you all for your replies. I changed the implementation so I won't require to do it, it was a poor design that has thrown me to the place I needed to do that.
I was sending serialized objects through the network. I wanted to add a header string in each message indicating the object being serialized so the other side can cast it in the right way.
I'm not sending serialized objects anymore, messages are embedded within a xml structure.
Thank you all, again. I really appreciate it.

Best regards.
