C# Reflection reference to another class from inside a DLL

Question

I have 2 classes, one is a DLL and the other is a.cs File and i want to call a Method in the.cs File from the DLL.

DLL

namespace SimpleDebugFormatting
{
    public static class DebugLog
    {
        private static Type debugFormat;
        private static Type DebugFormat
        {
            get
            {
                if (debugFormat == null)
                    return debugFormat = Assembly.GetExecutingAssembly().GetTypes().FirstOrDefault(_Type => _Type.Name.Contains("DebugFormat"));

                return debugFormat;
            }
        }

        public static List<string> GetMessages(IEnumerable _Parameters)
        {
            return (List<string>)DebugFormat.GetMethod("ConcatMessages", BindingFlags.Static | BindingFlags.NonPublic).Invoke(DebugFormat, new object[] { _Parameters });
        }
    }
}

.cs File

namespace SimpleDebugFormatting
{
    internal static class DebugFormat
    {
        internal static List<string> ConcatMessages(object[] _Messages) { }
    }
}

When both classes are.cs files it all works fine, but when the "DebugLog"-class is a DLL it can't find the "DebugFormat"-class.

When i try to print all types in the DLL's assembly with
" Assembly.GetExecutingAssembly().GetTypes() ",
it only shows these 2:

SimpleDebugFormatting.DebugLog
SimpleDebugFormatting.DebugLog+<>c

Why is that so and how can i get it to work?

Answer 1

Your DebugFormat class is marked as internal

Internal types or members are accessible only within files in the same assembly, as in this example:

So, you specifically asked DebugFormat not to be accessible by DebugLog . Make it public if you want it to be accessible.

Answer 2

Fixed it with this:

private static Type DebugFormat
{
    get
    {
        if (debugFormat == null)
            return debugFormat = AppDomain.CurrentDomain.GetAssemblies().FirstOrDefault(
                _Assembly => _Assembly.FullName.Contains("SimpleDebugFormattingAssembly")).GetTypes().FirstOrDefault(
                _Type => _Type.Name.Contains("DebugFormat"));

        return debugFormat;
    }
}

@JonasH, @Selvin, thx for the quick replies.

Answer 3

I went through a similar situation, and I found the class in this way. Write down the code to help not only the questioner but also others who see this article.

    public static Type DebugFormat
    {
        get
        {
            if (debugFormat == null)
            {
               return debugFormat = AppDomain.CurrentDomain.GetAssemblies().FirstOrDefault(
                        _Assembly => _Assembly.FullName.Contains("Assembly-CSharp")).GetTypes()
                   .FirstOrDefault(_Type => _Type.Name.Contains("namespace.classname"));
            }
            return debugFormat;
        }
    }

Sorry for not being good at English In addition, I also wrote a method to use regarding GetType()

Type assemblyType = Type.GetType("namespace.classname, Assembly-CSharp");
