Delphi 7 tguid compare

Question

有没有其他方法来比较2个TGUID元素，除了将它们转换为字符串（guidtostring函数）和评估表达式后，在Delphi 7中？

Answer 1

您可以使用IsEqualGUID API中声明SysUtils单元 。

Answer 2

IsEqualGUID() (or IsEqualIID()), like TOndrej suggested. You can also use SysUtuils. CompareMem() instead, since TGuid is a binary array of bytes.
