Add reference to the Dll from Another Dll

Question

Hi All...
Am developed C# application for creating dll for some functionality,am creating two dll's at a time,for example Dll A and Dll B.
This Dll A is reference of Dll B.
So how to call Dll A from Dll B.
Am using following code for this, but i got error message.

the Code is

 

public class Proxy : MarshalByRefObject

{

public Assembly GetAssembly(string assemblyPath)

{

try

{

return Assembly.LoadFile(assemblyPath);

}

catch (Exception)

{

return null;

// throw new InvalidOperationException(ex);

}

}

}

 

 

string dynamicClassPath = File Path;

AppDomain domains = AppDomain.CreateDomain("New domain name");

Type type = typeof(Proxy);

Proxy myObject = (Proxy)domains.CreateInstanceFromAndUnwrap(dynamicClassPath, type .FullName);

 

and the error is

Quote:

Could not load type 'FolderName.FileName+Proxy' from assembly 'Dynamic_id, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

here

Dynamic_id

is a dll.

 

for deep explanation

 

Dll A and B both are created dynamically.
The Following code in Dll A

 

using System;

namespace ForTest

{

public class Dynamic_Val_001

{

private string _Prop_Name;

private string _Prop_Address;

public virtual string Prop_Name

{

get

{

return this._Prop_Name;

}

set

{

this._Prop_Name = value;

}

}

public virtual string Prop_Address

{

get

{

return this._Prop_Address;

}

set

{

this._Prop_Address = value;

}

}

}

}

the Dll B code is

using System;

namespace ForTest

{

public class Val_001

{

public virtual Tuple<bool, string> isValid(Dynamic_Val_001)

{

return new Tuple<bool, string>(false, "Success");

}

}

}

Now the Dll B have a one tuple bool function with one parameter, In that parameter is Dll A class name,so Dll B is depends on dll A.

So how to Call that Dll A class from Dll B.

so pls help me how to do this??
sorry my poor English.

I think it's 4.0. If i check the IIS manager the connection fails when I click test connection. Authentication passes but Authorization fails with the message,

The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path.

I can't find any settings to change the read access for the application pool identity or anything similar to that, I've looked at advanced settings and basic settings of the application pool but don't understand them that well.

Did you create a Asp.Net 4.0 website? If yes then have you enabled the deployed website to use the .Net 4.0 Framework. By default it will be .Net 2.0.
