Question

在我的情况下，我需要从ac或c ++代码源调用powershell脚本，发现很少的链接非常笨拙而且不适合c ++，我只是想要一个路线图，如果它可能调用一个列出目录内容的powershell脚本来自用c或c ++编写的代码片段

Answer 1

C ++代码：

#include<iostream>
#include <io.h>   // For access().
#include <sys/types.h>  // For stat().
#include <sys/stat.h>   // For stat().
#include <string>
using namespace std;


void main()
{
       string strPath = "d:\\callPowerShell.ps1";
//access function:
       //The function returns 0 if the file has the given mode.
       //The function returns –1 if the named file does not exist or does not have the given mode
       if(access(strPath.c_str(),0) == 0)
       {

              system("start powershell.exe Set-ExecutionPolicy RemoteSigned \n");
              system("start powershell.exe d:\\callPowerShell.ps1");
              system("cls");
       }
       else
       {
              system("cls");
              cout << "File is not exist";
              system("pause");
       }
}

Answer 2

第一个错误：

#include <io.h>   // For access().

访问权在此库中：

#include <cstdlib>

下一步：

错误：未在此范围内声明'system'

#include <unistd.h>

最后：

caractere '\'是C / C ++的一个特殊问题，然后您必须添加另一个'\'，如：

system("start powershell.exe C:\\users\\sqtk-mal\\script1.ps1");

Answer 3

在C ++中

#include <cstdlib>

std::system("command");

在c

#include <stdlib.h>

system("command");

Answer 4

 #include<iostream>
 #include <io.h>   // For access().
 #include <sys/types.h>  // For stat().
 #include <sys/stat.h>   // For stat().
 #include <string>
 using namespace std;


 int main()
 {
   string strPath = "C:\users\sqtk-mal\script1.ps1";
   //access function:
   //The function returns 0 if the file has the given mode.
   //The function returns –1 if the named file does not exist or does not have the given mode
   if(access(strPath.c_str(),0) == 0)
   {

          system("start powershell.exe Set-ExecutionPolicy RemoteSigned \n");
          system("start powershell.exe C:\users\sqtk-mal\script1.ps1");
          system("cls");
   }
   else
   {
          system("cls");
          cout << "File is not exist";
          system("pause");
   }
}

使用此代码时，代码块会出错
