如何向wix安装项目添加自定义操作

Question

我的解决方案中有2个项目:

1).自定义操作类(CustomAction)

2).Wix安装项目(TestSetup)

CustomAction项目中有CustomAction.cs:

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using Microsoft.Deployment.WindowsInstaller;

namespace CustomAction
{
    public class CustomActions
    {
        [CustomAction]
        public static ActionResult CustomAction1(Session session)
        {
            File.Create(@"c:\installed.txt");

            return ActionResult.Success;
        }
    }
}

Product.wxs:

<?xml version="1.0" encoding="UTF-8"?>

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <Product Id="*" Name="TestSetup" Language="1033" Version="1.0.0.0" Manufacturer="SB2"
           UpgradeCode="39d922d3-a3f5-4207-b905-124615dda25d">
    <Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" />

    <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
    <MediaTemplate EmbedCab="yes"/>

    <Feature Id="ProductFeature" Title="TestSetup" Level="1">
      <ComponentGroupRef Id="ProductComponents" />
    </Feature>
    <InstallExecuteSequence>
      <Custom Action="CustomAction" Before="InstallFinalize" />
    </InstallExecuteSequence>
  </Product>

  <Fragment>
    <Directory Id="TARGETDIR" Name="SourceDir">
      <Directory Id="ProgramFilesFolder">
        <Directory Id="INSTALLFOLDER" Name="TestSetup" />
      </Directory>
    </Directory>
  </Fragment>
  <Fragment>
    <ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER">
      <Component Id="result.rtf">
        <File Id="result.rtf" Source="result.rtf" KeyPath="yes" Checksum="yes" />
      </Component>
    </ComponentGroup>
  </Fragment>

<Fragment>
    <CustomAction Id='CustomAction' BinaryKey='CustomAction.CA' DllEntry='CustomAction' />
    <Binary Id='CustomAction.CA' SourceFile='..\CustomAction\bin\Debug\CustomAction.CA.dll' />
</Fragment>  
</Wix>

安装项目建立没有问题,但当我尝试运行它时,我收到一条错误消息:"此Windows Installer程序包有问题.无法运行此安装所需的DLL.请联系您的支持人员或包装供应商"

我认为这是因为二进制源文件值不正确.你会说明如何解决它吗？

Answer 1

问题是您的CustomAction方法名称"CustomAction1"与您提到的"DLLEntry"值不匹配(DllEntry ='CustomAction').你错过了"1":)

<CustomAction Id='CustomAction' BinaryKey='CustomAction.CA' DllEntry='CustomAction' />

Answer 2

你应该这样写: -

<CustomAction Id='CustomAction' BinaryKey='CustomAction.CA' DllEntry='CustomAction1' />

其中CustomAction1是您的CustomAction名称..
