如何使DLL内的Wix调用函数没有错误？

Question

我的问题是明确的窗口具有访问DLL InstallTools.dll因为我打电话里面OpenExeUrl

这里的功能是我的DLL内容问题

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using Microsoft.Deployment.WindowsInstaller; 
using System.Configuration; 
using System.Diagnostics; 

namespace InstallTools 
{ 
    public class InstallHelper 
    { 
     [CustomAction] 
     public static ActionResult OpenExeUrl(Session session) 
     { 
      try 
      { 
       var exeUrl = InstallTools.Properties.Settings.Default.EXEURL; 
       // Prepare the process to run 
       ProcessStartInfo start = new ProcessStartInfo(); 
       int exitCode = 0; 
       // Enter in the command line arguments, everything you would enter after the executable name itself 
       //start.Arguments = arguments; 
       // Enter the executable to run, including the complete path 
       start.FileName = exeUrl; 
       // Do you want to show a console window? 
       start.WindowStyle = ProcessWindowStyle.Maximized; 
       start.CreateNoWindow = true; 

       // Run the external process & wait for it to finish 
       using (Process proc = Process.Start(start)) 
       { 
        proc.WaitForExit(); 

        // Retrieve the app's exit code 
        exitCode = proc.ExitCode; 
       } 
      } 
      catch (Exception e) 
      { 
       var errorMessage = "Cannot open exe file ! Error message: " + e.Message; 
       session.Log(errorMessage); 
      } 

      return ActionResult.Success; 
     } 
    } 
} 

的维克斯文件内容：

<?xml version="1.0" encoding="UTF-8"?> 
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">

    </InstallExecuteSequence> 
    </Product> 

    <Fragment> 
    <Directory Id="TARGETDIR" Name="SourceDir"> 
     <Directory Id="ProgramFilesFolder"> 
     <Directory Id="INSTALLFOLDER" Name="MySetup" /> 
     </Directory> 
    </Directory> 
    </Fragment> 

    <Fragment> 
    <DirectoryRef Id="INSTALLFOLDER"> 
     <Component Id="myAppFile"> 
     <File Source="$(var.MyApplication.TargetPath)" /> 
     </Component> 
    </DirectoryRef> 
    <ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER"> 
     <!-- TODO: Remove the comments around this Component element and the ComponentRef below in order to add resources to this installer. --> 
     <!-- <Component Id="ProductComponent"> --> 
     <ComponentRef Id="myAppFile" /> 
     <!-- </Component> --> 
    </ComponentGroup> 
    </Fragment> 

</Wix> 

您可以注意到我通过构建自定义操作并将其添加到执行顺序来调用dll。

<CustomAction Id="OpenExe" BinaryKey="InstallTools" DllEntry="OpenExeUrl" Execute="deferred" Impersonate="yes" /> 
    <!--<CustomAction Id="OpenExe" Return="ignore" Directory="ProgramFilesFolder" ExeCommand="C:\Program Files (x86)\Notepad++\notepad++.exe" Impersonate="yes" Execute="deferred"/>--> 
    <InstallExecuteSequence> 
     <Custom Action="OpenExe" Before='InstallFinalize'/> 
    </InstallExecuteSequence> 

我的问题是，当我启动安装程序时，出现以下屏幕截图所示的此错误。

您能否请指教？

Answer 1

1）使您的CustomAction类公开：public class InstallHelper。

2）确保你引用了正确的DLL，它应该以* .CA.dll扩展名结尾。你的bin文件夹有两个dll文件：InstallTools.dll,InstallTools.CA.dll。
