> char 0x00ad not allowed in identifier

Full source, please. And you should use `File.tmpfile()` instead of `tmpfile()` (unless you are already in `with(File)`?). This compiles:
---
import std.stdio;

void main() {
    with(File) File tmp = tmpfile();
}
---

Anyway, 0x00ad is 'SOFT HYPHEN' (not a '_' char) and is valid but ignorable in a Java identifier. Looks like your editor added it.

By the way, you just inspired me to fill this:

thanks is was mine stupid error.

Then now i have this:
--------------------------
cat tmp.d
import std.string;
import std.stdio;

void main(  ){
    File tmp = File.tmpfile();
    tmp.writeln( "ok" );
    tmp.writeln( "D is Fun" );
    writefln( "fileName: %s", tmp.name );
    foreach( line; tmp.byLine() )
        writefln( "l: %s", line );
}

--------------------------
$ ./tmp
fileName:
--------------------------

Why i do not get the file name ?
why i can not iterate over line?

You can, but the file is still open and you are at the end of the file.

Try:
     tmp.rewind;
     foreach( line; tmp.byLine() )
         writefln( "l: %s", line );
