如何在visualc++；快车2010 我试图在VS C++ Express 2010中编译C代码，但是我得到以下错误跟踪： 1>------ Build started: Project: test4, Configuration: Release Win32 ------ 1>cl : Command line error D8045: cannot compile C file 'test4.c' with the /clr option ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== 1>------ Build started: Project: test4, Configuration: Release Win32 ------ 1> test4.cpp 1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(86): error C2664: 'CreateFileW' : cannot convert parameter 1 from 'const char [13]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(98): error C2664: 'CreateFileW' : cannot convert parameter 1 from 'const char [13]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(138): error C2664: 'OpenServiceW' : cannot convert parameter 2 from 'const char [9]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(196): error C2664: 'GetSystemDirectoryW' : cannot convert parameter 1 from 'CHAR [80]' to 'LPWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(203): error C2664: 'lstrcatW' : cannot convert parameter 1 from 'CHAR [80]' to 'LPWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(208): error C2664: 'CopyFile' : cannot convert parameter 1 from 'const char [13]' to 'LPCTSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(236): error C2664: 'CreateServiceW' : cannot convert parameter 2 from 'const char [9]' to 'LPCWSTR' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>test4.cpp(27): error C3861: 'kbhit': identifier not found ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

/clr意味着使用.Net运行时，而不是c语言运行时

只需调用文件.c，它就可以工作了，有一个标志阻止你使用任何C++特性。

---

转到属性->c/c++->高级->编译为并选择“c”

创建项目时，请确保将其创建为Win32程序，而不是CLR应用程序。可以在“项目属性”下更改此设置

属性->公共语言运行时支持是您需要的设置。

---

将其设置为无。

首先，您应该删除

/clr

，这不是您想要的

回答问题的根本问题：您正在将

char

数组传递给LPWSTR和LPCWSTR以及LPCTSTR，它们都是双字节char数组，因此

wchar\u t*

具有某种形式或其他形式（如果定义了UNICODE，否则最后一个就是普通的

char*

-like）

---

您必须撤消UNICODE定义（不推荐）或转换

char[]<代码> > char *>代码> WCARYTT < /C>类型，我按照您的建议执行，我仍然在获取命令行错误D8045：不能用/CLR optOnt//CLR optuuon编译C文件'Test4.c '，这是MSFT奇怪的C++与C／N.NETNEX的混合，默认情况下Visual C++编译器用.c编译文件。扩展为C和.cp扩展为C++的文件。如果您使用这两个标准扩展名，则不需要更改此设置。@James-我认为compile-as-c-flag会对“/”注释之类的内容发出警告，即使使用.c文件（自从我使用它以来已经有几个版本了）。使用.cpp扩展名编译时出现的错误表明您混淆了
wchar\u t
和
char
。即使将此文件编译为C文件，也需要修复这些错误。
