Casting gremlins

[Todd]

In C it was possible to cast a Uint to a Char[], however, I can't seem to get it to compile in D. 

example: I have 

uint data1;
long data;
long lblonedata;
.
.
.
char[] dataone = cast(char[]) data1;
lblonedata = atoi(dataone);

I'm importing std.string, std.conv;

and get e2ir: cannot cast uint to char[]

I was using dmd 1.022 and switched to 2.x today with no help.
Does D use a different method? or I'm I missing something obvious?
