不好意思,我原来写的是WriteString.所以没注意
反正把那个默认的读取改成 '' 就行了

var registry:tregistry;
s:string;
begin
Registry:=TRegistry.Create;
Registry.RootKey:=HKEY_CLASSES_ROOT;
Registry.OpenKey('/.txt',False);
s :=Registry.ReadString('');
Registry.Free;
showmessage(s);
end;

测试通过 ///

toz9945: 权限不够不可能读出来的.. 部分权限只能读取属于自己权限范围内的注册表信息.

注意TRegIniFile,TRegistry的区别
var
hReg: TRegIniFile;
iReg: TRegistry;
begin
hReg := TRegIniFile.Create('');
hReg.ReadString()
iReg.ReadString()

hReg:=TRegIniFile.Create('/Software/Classes/CLSID
/{992CFFA0-F557-101A-88EC-00DD010CCC48}');
str:=hReg.ReadString('','DefaultIcon',default);
end;
