Maybe also the Array.Sort[^] method is an alternative for you.

How can I unload the assembly in c#

i have winapp that use dll (assembly)
im createing in runtime object from the assembly.
then destroy this object.

THEN , while the winapp is STILL RUNNING , i want to Recompile the dll (assembly) , and to use the winapp AGAIN to create object from that assembly .(this way i could ,change the code of the object ,if i found bug, and use it again).

since there was no method like Assembly.Unload(), I use AppDomain,
but with that I still can't unload the assembly.

Here is what my program going

---
class Program
{
static void Main(string[] args)
{
MyTest.Test();
}
}

public class MyTest
{
public static void Test()
{
string assemblyFile = @"D:\XC.dll"; //(1)

string typeName = "XC.Form1"; //(2)

AppDomain appDomain = AppDomain.CreateDomain("Domain test");

try
{
ObjectHandle oh = appDomain.CreateComInstanceFrom(assemblyFile, typeName);
object o = oh.Unwrap();
IXC ixc = (IXC)o; //(3)
}
catch (Exception ex)
{
}
}
};
--
(1)the assebmly file path I want to load
(2)the Type I want to create which implement the IXC interface, and the IXC interface was in the assembly "develop.dll" which is used by the winapp
(3) when it goes to here, I got a exception:
$exception {"Type 'XC.Form1' in assembly 'XC, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable."} System.Exception {System.Runtime.Serialization.SerializationException}
--

Any help would be appretiated!

What you are trying to attempt is alot more complicated than what you have there. There are many rules to remoting that must be understood, else you will spend weeks on a pointless journey. Specifically focus on types crossing domain boundries.

Regarding the issue @ (3). Your type has to be marked Serializable or inherit from System.MarshalByRefObject. There could be more, but that is the general way.

But if I have IXC inherit from System.MarshalByRefObject
then I got a new exception, says: "Unable to cast transparent proxy to type 'IXC'".

Hi
As leppie said, this gets quite complicated.

In answer to your question, you unload the whole AppDomain, not individual assemblies.

Also, cross-domain calls are slow - this may or may not be a factor for you.

You might want to load your assembly into your main AppDomain. You could copy it first and load it from the copy so that the original file is not locked. Then you can re-compile and repeat the process for the new assembly - they will be treated as different if they have different version numbers.

You have far better chances to get help if you post the question in the correct forum, e.g. the VC++ forum.
