How to create a new object.

[gana]

Hello,

string typename = obj.GetType().FullName;
where obj is a object of any type.

Now my problem is how to create back the object just by passing this typename.

Thanks for the help.

In the reflection Namespace there's a calls called Activator. On that
class you use the method CreateInstance

Thank you. But I have FullName of the Type not the assembly. In Activator
class I need to pass either Type or FullName of the assembly.
So How to do this?

You have the full name of the type, but you don't know what assembly its in? If thats the case then you are stuck, consider this code

Assembly 1
namespace Richard
{
class Hello
{
public void Foo()
{
}
}
}

Assembly 2
namespace Richard
{
class Hello
{
public void Bar()
{
}
}
}

now I write the code in my application assembly

Activator.CreateInstance(Type.GetType("Richard.Hel lo));

So the question is, which class is it meant to create, the one from assembly 1 or the one from assembly 2? Thats why you need the assembly name.

So, don't save just the name--- Save the Type.

Hello,
Thank you. My first option was to store the type itself. But I coudnt
Serilaize the object which has a public field of type System.Type. I was
getting the exception with Messgae" There was an error reflecting type
classname". If I store the fullName instead of Type itself it worked fine.
Will loading all the assemblies before trying to create the object cause any
performance issues?
