Marshaling structure to string

Question

I have a struct for concat string datas.

 public struct MyClass1
    {

        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 5)]
        public string Name;

        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 5)]
        public string SurName;
    }

I set the value struct fields.

MyStruct mystr = new MyStruct();

mystr.Name = 'John';
mystr.SurName = 'Smith';

I want to concat this string by using Marshaling and get the value as

"John Smith"

. Is it possible using marshaling ?

Answer 1

Use reflection instead of marshalling.

 var myClass = new MyClass1 { Name = "John", SurName = "Smith" };
 Console.WriteLine(MyMarshal(myClass));

static string MyMarshal(object item)
{
  var values = new List<object>();
  foreach (var field in item.GetType().GetFields())
  {
    values.Add(field.GetValue(item));
  }
  return string.Join(" ", values.ToArray());
}

public struct MyClass1 
{  
    public string Name; 

    public string SurName; 
}
