创建字符串并将其保存到.txt文件中的最简单方法是什么？

我为C Enum写了一个delphi数字你能回答我,我在哪里可能有错？有什么不对的吗？

C:

 typedef  enum {
   AttributeStandardInformation = 0x10,
   AttributeAttributeList = 0x20,
   AttributeFileName = 0x30,
   AttributeObjectId = 0x40,
   AttributeSecurityDescriptor = 0x50,
   AttributeVolumeName = 0x60,
   AttributeVolumeInformation = 0x70,
   AttributeData = 0x80,
   AttributeIndexRoot = 0x90,
   AttributeIndexAllocation = 0xA0,
   AttributeBitmap = 0xB0,
   AttributeReparsePoint = 0xC0,
   AttributeEAInformation = 0xD0,
   AttributeEA = 0xE0,
   AttributePropertySet = 0xF0,
   AttributeLoggedUtilityStream = 0x100

} ATTRIBUTE_TYPE

并转换为delphi枚举:

ATTRIBUTE_TYPE=( AttributeStandardInformation = $10,
   AttributeAttributeList = $20,
   AttributeFileName = $30,
   AttributeObjectId = $40,
   AttributeSecurityDescriptor = $50,
   AttributeVolumeName = $60,
   AttributeVolumeInformation = $70,
   AttributeData …

考虑我的示例代码:

var p512Sector:PByte;
.....
getmem(p512Sector, 262144);
FillChar( p512Sector,262144 ,0);

当我运行程序时,Delphi给了我一个违规访问错误.为什么？
