Hi, This is my code:

C#

        private void form_Load(object sender, EventArgs e)
        {
 string s = Directory.GetCurrentDirectory()+@"\plugin";
            Assembly assembly = Assembly.LoadFrom(s);
            AssemblyName assemblyn = assembly.GetName();
            MessageBox.Show(assemblyn.ToString());
}

When i trace my program the code in line 2 onwards will not run!!
I change it repeatedly but the code that related to Assembly class will not run and does not allow to subsequent code run also!

From comment: I want load my dll files from directory without use these names, in other hand i dont know the name of dll files.

You need to provide the full path and file name to Assembly.LoadFrom(..)[^], e.g.:

C#

Assembly assembly = Assembly.LoadFrom(@"c:\test\MyAssembly.dll");

But you only provided a path (or, if "plugin" is the name of the file, you have to append ".dll" or, unlikely but possible, ".exe").

Edit after comment:

To load all assemblies from a specific directory, you can use Directory.EnumerateFiles(..)[^] to retrieve all (matching) files from the directory and then loop over the IEnumerable<string>-result to load them one by one. (The linked page has a sample code.)
