Question

I’ve the following class in XmlSer.dll

namespace xmlser {         public class XmlSer         {                 public Type test(string s)                 {                     return Type.GetType(s);                 }          //...other code          } } 

and the following code in MyApp.exe, which links XmlSer.dll as a reference

namespace MyApp {     public class TestClass     {         public int f1 = 1;         public float f2 = 2.34f;         public double f3 = 3.14;         public string f4 = 'ciao';     }      class MainClass     {          public static void Main(string[] args)         {             TestClass tc = new TestClass();             XmlSer ser = new XmlSer();             Console.WriteLine(ser.test('MyApp.TestClass')!=null);         } } 

Running MyApp.exe I get false, that means that ser instance of XmlSer is not able to get the type of Testclass (result is null). Putting XmlSer class directly in MyApp.exe code I correctly get the type of TestClass.

Checking on the net i’ve found that the problem is related to the assemblies. That means, the assembly of .exe is not visible to the XmlSer.test method so it can’t resolve the type of TestClass.

How can I resolve the problem maintaing XmlSer in XmlSer.dll and MyApp.MainClass in MyApp.exe ?

Thanks.

Since the two are not in the same assembly, you probably need to include the assembly name in the type string:

Console.WriteLine(ser.test('MyApp.TestClass, MyApp')!=null);

If all you want to do is serialize arbitrary objects, you can do the following:

public static class Serialization {     public static void Serialize(object o, Stream output)     {         var serializer = new XmlSerializer(o.GetType());         serializer.Serialize(output, o);     } }
