Visual Studio 的 C 支持 #pragma message() 宏可以用来输出一些信息。于是编写一个代码进行测试：
#include <Uefi.h>
#include <Library/UefiLib.h>
#include <Library/ShellCEntryLib.h>
/***
Print a welcoming message.
Establishes the main structure of the application.
@retval 0 The application exited normally.
@retval Other An error occurred.
***/
INTN
EFIAPI
ShellAppMain (
IN UINTN Argc,
IN CHAR16 **Argv
)
{
#pragma message (__FILE__)
return(0);
}
@echo off
set "t=%time%"
::You code start here
::You code end here
set "t1=%time%"
if "%t1:~,2%" lss "%t:~,2%" set "add=+24"
set /a "times=(%t1:~,2%-%t:~,2%%add%)*3600+(1%t1:~3,2%%%100-1%t:~3,2%%%100)*60+(1%t1:~6,2%%%100-1%t:~6,2%%%100)"
echo Time Used %times% Seconds
pause
上述代码合在一起进行测试：
@echo off
set "t=%time%"
::You code start here
CHOICE /T 3 /C ync /CS /D y
::You code end here
set "t1=%time%"
if "%t1:~,2%" lss "%t:~,2%" set "add=+24"
set /a "times=(%t1:~,2%-%t:~,2%%add%)*3600+(1%t1:~3,2%%%100-1%t:~3,2%%%100)*60+(1%t1:~6,2%%%100-1%t:~6,2%%%100)"
echo Time Used %times% Seconds
pause
