C 键\值\部分\信息结构数据属性

我正在编写一个过滤器驱动程序，我想读取存储在注册表项中的字符串（REG_SZ是注册表中字符串的类型）。我使用函数ZwQueryValueKey（）读取注册表，使用KEY\u VALUE\u PARTIAL\u信息结构来接收数据。我不知道如何使用data属性，所以我在for循环中打印了它，如下所示：

for(int i=0; i<pKeyInfo->DataLength, i++){
    DbgPrint("Data from Registry: %C", pKeyInfo->Data[i]);
}

但实际上我得到了

Data from Registry: F
Data from Registry:
Data from Registry: O
Data from Registry:
Data from Registry: L
Data from Registry:
Data from Registry: D
Data from Registry:
Data from Registry: E
Data from Registry:
Data from Registry: R
Data from Registry:
Data from Registry:
Data from Registry:
Data from Registry:

---

有人知道为什么要在两者之间添加这些空格吗？我还想将其从UCHAR数组转换为wchar\t字符串或wchar\t数组。谢谢

我从

%d

开始，而不是

%C

，这样你就可以准确地看到数组中的内容了。或者使用调试器查看数组。

Data from Registry: F
Data from Registry:
Data from Registry: O
Data from Registry:
Data from Registry: L
Data from Registry:
Data from Registry: D
Data from Registry:
Data from Registry: E
Data from Registry:
Data from Registry: R
Data from Registry:
Data from Registry:
Data from Registry:
Data from Registry:
