Hi,

I have created an object dynamically using Reflection. I am calling a service to get the data from this object.

It is throwing error like.

The underlying connection was closed: The connection was closed unexpectedly.

C#

public Object ProjectProperties
       {
           get;
           set;
       }

C#

var myType = CompileResultType();
           var myObject = Activator.CreateInstance(myType);

I want to return myObject to the service in this format {sucess:true,Propjectproperties:{p1:v1,p2:v2}}
where Propjectproperties is dynamic type.

How can i return the object service which is created dynamically.?

Thanks in Advance for your responses and suggestions.. :)

I guess the error nothing do with your logic. Make sure that you have a valid connection string and place the statements in try... catch and find the exception.

What type is returned from Activator.CreateInstance? If it is an object, it would create problems with methods from the service. Other then that, ensure that your connection is opened and add try...catch blocks to see what happens when you try to connect (stack trace).

its dynamic object.I have problem with returning dynamic object to the service.

Sinisa Hajnal 24-Mar-15 7:53am

It is dynamic object, but CreateInstance returns Object type. That is why I asked what type do you get...does your var holds object or correct type for the service?

its holds object type..

Also, the service doesn't care how you create the object as long as it matches its signature. So, the service in this particular case makes no difference, just create the format you need.

what should be the return type when i want return the object which is created dynamically and added data to it..

Sinisa Hajnal 24-Mar-15 14:04pm

I don't know, it is your project. I'm not asking you what should be (although it should be something that the service accepts). I'm asking what is the type after CreateInstance call. Set a breakpoint and check.

You have to cast the object into correct type otherwise you cannot do anything with the object except pass it to the service...and then service tries to call something on the object and it doesn't find suitable method because it is an OBJECT which has only GetType method.

as it a dynamic property class which is created at run time.then how should i know the return type..

Sinisa Hajnal 26-Mar-15 2:54am

How could you not? You're calling create instance with the type name.

i did not get your point.Can you please brief this.

Sinisa Hajnal 27-Mar-15 8:04am

Explanation: You're calling CreateInstance (typeName)...this type name you know from some runtime method.

Cast the resulting object into suitable type based on that typeName (which you obviously know or you couldn't create an instance).

Better yet, create an interface, have all the classes you can generate implement the interface and cast into that.

Is this clearer?

"I am calling a service to get the data from this object."

Whatever this is, you need to explain it more clearly.
