You have code like this:

class FileName
{
     string name;

     this(string name)
     {
         this.name = name;
     }
...

void ReadFile()
{
     auto file = new FileName();
...

As you see you define a costructor that accepts a string, but 
then when you allocate the class you don't give it a string.

So the correct code is:

void ReadFile()
{
     auto file = new FileName("somestring");
...



More notes:
- By convention in D method/function names start with a lower 
case.
- Don't indent module-level functions (like ReadFile).
- If your program is composed by more than one module, I suggest 
to add a name at the top of the imported module, like "module 
Foo;".
- In D structs are used quite often.
