C# 使用MSIEnumRelatedProducts和MSIGetProductInfo的MSI互操作

在使用MSI互操作API时，我遇到了一些异常行为，导致我的应用程序崩溃。“处理”这个问题很简单，但我想知道更多关于“为什么”会发生这种情况的信息

我对MSIEnumRelatedProducts的第一次调用返回值0，并将字符串缓冲区正确设置为productcode。我的理解是，只有当给定的升级代码（作为parm传递给方法）当前安装了“相关系列产品”时，才会发生这种情况，否则它将返回259个错误项

但是，当我随后使用相同的productcode调用MSIGetProductInfo时，我得到了返回值1605，“此操作仅对当前安装的产品有效。”

有人知道在什么情况下会发生这种情况吗？它在一台机器上100%可重复，但我还没有在另一台机器上获得复制步骤

我们的所有产品都是使用Wix属性“AllUsers=1”构建的，因此应该为所有用户安装产品，而不仅仅是一个用户

任何想法/建议都将不胜感激

谢谢 本

更新： 我注意到，当运行带有日志记录的问题msi包时，会显示以下行：

MSI（88:68）[12:15:50:235]：FindRelatedProducts:无法读取产品“{840C…etc…96}”的分配类型信息。跳过

有人知道这意味着什么吗

更新：代码示例。

do
{
   result = _MSIApi.EnumRelatedProducts(upgradeCode.ToString("B"), 0, 
                                        productIndex, productCode);
   if (result == MSIApi.ERROR_BAD_CONFIGURATION ||
       result == MSIApi.ERROR_INVALID_PARAMETER ||
       result == MSIApi.ERROR_NOT_ENOUGH_MEMORY)
   {
      throw new MSIInteropException("Failed to check for related products", 
                                     new Win32Exception((Int32)result));
   }

   if(!String.IsNullOrEmpty(productCode.ToString()))
   {
      Int32 size = 255;
      StringBuilder buffer = new StringBuilder(size);
      Int32 result = (Int32)_MSIApi.GetProductInfo(productCode, 
                             MSIApi.INSTALLPROPERTY_VERSIONSTRING, 
                             buffer, 
                             ref size);

      if (result != MSIApi.ERROR_SUCCESS)
      {               
         throw new MSIInteropException("Failed to get installed version", 
                                        new Win32Exception(result));
      }

      version = new Version(buffer.ToString());
   }

我假设您尝试使用获取文档中描述的其他属性。例如，您可以毫无问题地获取

“PackageCode”

属性（

INSTALLPROPERTY\u PackageCode

）的值，但是您无法获取与1605错误（

error\u UNKNOWN\u PRODUCT

）相关的

“UpgradeCode”

属性的值并接收该错误

更新：好的，现在我明白你的问题了。你如何在互联网上发现有一个漏洞，所以它并不总是有效的。有时它会返回1605（

ERROR\u UNKNOWN\u PRODUCT

）或1608（

ERROR\u UNKNOWN\u PROPERTY

）。在这种情况下，唯一的解决方法是手动获取version属性。我可以用Microsoft Office Outlook 2010 MUI（UpgradeCode=“{00140000-001A-0000-0000-0000000 FF1CE}”）重现您在我的计算机上描述的问题，并编写一个解决方法，从注册表获取产品版本。在本例中，我仅从

尝试获取PackageCode时返回相同的1605。这似乎没有什么不同，如果API认为产品没有安装，那么我认为更改属性不会有什么不同。不过谢谢你的建议。@Ben Cawley:我可以给你发一些工作代码示例。我想知道你到底想要什么。你知道升级代码并尝试获取相关产品的信息吗？或者你想获取只有ProductCode的升级代码的信息吗？嗨，Oleg，我确实有适用于大多数情况的工作代码。不幸的是，由于msi包或我试图安装它的机器的某些奇怪状态，似乎正是这个“一个”msi导致了问题。我正在使用已知的“升级代码”获取产品代码。我将用代码示例更新我的问题。嗨，Oleg，谢谢你提供的信息。我确实试着先用谷歌搜索这个问题，但什么也没找到。你能发布关于MSIGetProductInfo中已知错误的链接吗？你知道MSIGetProductInfoEx是否也有同样的问题吗？我可以先试试。谢谢同时，提姆
