从c＃中的vbscript函数返回值 [英] Return a value from vbscript function in c#

问题描述

我从c＃中的代码执行.vbs文件以检查用户的真实性。我传递用户名和密码值，在登录点击.vbs将运行和认证用户。如果用户在不认证然后函数在vbs返回一个值，我怎么能在我的代码在c＃中获得该值，并使用它在应用程序的UI中显示正确的错误消息。
请帮助..

解决方案

不显示生产代码，但显示

demo.cs：

  
 using System.Diagnostics; 
 
命名空间演示
 {
 public class Demo 
 {
 public static void Main（string [] args）{
 string user = nix; 
 if（1< = args.Length）{user = args [0];}; 
 string passw =nix; 
 if（2< = args.Length）{passw = args [1];}; 
 string cscript =cscript; 
 string cmd = string.Format（\.. \\vbs\\auth.vbs\{0} {1}，user，passw）; 
 System.Console.WriteLine（{0} {1}，cscript，cmd）; 
 
流程process = new Process（）; 
 process.StartInfo.UseShellExecute = false; 
 process.StartInfo.RedirectStandardOutput = true; 
 process.StartInfo.CreateNoWindow = true; 
 process.StartInfo.FileName =cscript.exe; 
 process.StartInfo.Arguments = cmd; 
 try {
 process.Start（）; 
 System.Console.WriteLine（process.StandardOutput.ReadToEnd（））; 
 System.Console.WriteLine（process.ExitCode）; 
} catch（Exception ex）{
 System.Console.WriteLine（ex.ToString（））; 
} 
} 
} 
} 
  

auth .vbs：

 选项显式
 
 Dim nRet：nRet = 2 
如果WScript。 Arguments.Count = 2 then 
如果user= WScript.Arguments（0）和passw= WScript.Arguments（1）然后
 WScript.Echook
 nRet = 0 
否则
 WScript.Echo失败
 nRet = 1 
结束如果
否则
 WScript.Echo坏
结束如果
 WScript.Quit nRet 
  

输出：

  demo.exe 
 cscript..\vbs\auth.vbsnix nix 
 fail 
 
 1 
 
 demo.exe用户passw 
 cscript..\vbs\auth.vbs用户passw 
 ok 
 
 0 
  

也许你可以通过忘记文本返回并简单地使用.Exitcode。

I am executing a .vbs file from my code in c# for checking the authenticity of user. I am passing username and password values and on login click .vbs will run and authenticate the user. If the user in not authentic then function in vbs returns a value, how can i get that value in my code in c# and use it to display proper error message in UI of application. Please help..

Not to present production code, but to show

1. that/how it 'works in principle'
2. what keywords/components you have to look up in the docs

demo.cs:

using System;
using System.Diagnostics;

namespace Demo
{
    public class Demo
    {
        public static void Main(string [] args) {
            string user  = "nix";
            if (1 <= args.Length) {user = args[0];};
            string passw = "nix";
            if (2 <= args.Length) {passw = args[1];};
            string cscript = "cscript";
            string cmd = string.Format("\"..\\vbs\\auth.vbs\" {0} {1}", user, passw);
            System.Console.WriteLine("{0} {1}", cscript, cmd);

            Process process = new Process();
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.RedirectStandardOutput = true;
            process.StartInfo.CreateNoWindow = true;
            process.StartInfo.FileName = "cscript.exe";
            process.StartInfo.Arguments = cmd;
            try {
              process.Start();
              System.Console.WriteLine(process.StandardOutput.ReadToEnd());
              System.Console.WriteLine(process.ExitCode);
            } catch (Exception ex) {
              System.Console.WriteLine(ex.ToString());
            }
        }
    }
}

auth.vbs:

Option Explicit

Dim nRet : nRet = 2
If WScript.Arguments.Count = 2 Then
   If "user" = WScript.Arguments(0) And "passw" = WScript.Arguments(1) Then
      WScript.Echo "ok"
      nRet = 0
   Else
      WScript.Echo "fail"
      nRet = 1
   End If
Else
   WScript.Echo "bad"
End If
WScript.Quit nRet

output:

demo.exe
cscript "..\vbs\auth.vbs" nix nix
fail

1

demo.exe user passw
cscript "..\vbs\auth.vbs" user passw
ok

0

Perhaps you can simplify things by forgetting the text return and use the .Exitcode only.
