编译 snippets.cpp 时出现以下错误消息。当调用 LoadFile 时会发生这种情况。我正在使用 simpleIni4.2

从编译器的错误消息来看，当函数需要一个指向宽字符串的指针时，您似乎传递的是一个窄字符串文字。

尝试L在字符串文字之前指定，以便将指向宽字符串文字（即类型为 的对象const wchar_t[]）的指针传递给 GetAllKeys()`：

GetAllKeys(L"Whatever\\Your\\Key\\Is");
//       ^

另外，请注意还有更多此错误的实例。具体来说，您应该将上述内容应用于编译器报告错误的所有调用，包括对以下函数的调用：

  • GetAllKeys()
  • GetValue()
  • SetValue()
  • Delete()

以及我无法从您发布的错误消息中推断出的所有其他可能情况。
