Have an error to use a string combined into a path to run the object

[YuJie]

Hello guys~

I got problem
this is my code:

     MainForm mainForm = this.ParentForm as MainForm;
     string strassemblyName = string.Empty;
 
     strassemblyName = "PowerOne.Win.Order".ToString();
     //Assembly
 
     System.Reflection.AssemblyName assemblyName = new System.Reflection.AssemblyName();
 
     assemblyName.Name = strassemblyName;
 
     AppDomain appDomain = AppDomain.CurrentDomain;
     System.Reflection.Assembly tmpass = appDomain.Load(assemblyName);
 
     CustomerTypeEdit form =            (CustomerTypeEdit)tmpass.CreateInstance("PowerOne.PowerOne.Win.Order.CustomerTypeEdit", true);
 
     form.Show();

But this "form" is still null
Who can help me to fix it?????

I've used the static class Activator to create instances from an assembly qualified name before.

For example:

string aqn = "System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089";
Type type = Type.GetType(aqn);
int i = (int)Activator.CreateInstance(type);
 

Look at how the AssemblyQualifiedName is put together. "Full.Namespace.ClassName, Assembly.Name, Version, Culture, PublicKeyToken".

You can find the AQN with this code:

Console.WriteLine(typeof(Int32).AssemblyQualifiedName);

You just need to plug in the type of the object you're using.

What are you trying to do?
You can get path of your currently executing assembly using:

Assembly.GetStartUpPath();
