我一直在尝试找到一种方法来获取给定产品代码的 Windows Installer 组件代码。（我实际上是在尝试使用不包含组件代码的快捷方式来获取已安装产品的组件路径，但这是一个更长的故事。）

我遇到了 WiX DTF (Microsoft.Deployment.WindowsInstaller) 程序集，这看起来是完成 MSI 工作的好方法。当我编写以下代码时，我充满希望：

Session product = Installer.OpenProduct(productCode);
ComponentInfoCollection components = product.Components;
ComponentInfo component = components.FirstOrDefault();

我希望我可以从 ComponentInfo 中获取组件代码。不幸的是，我认为没有办法做到这一点。

是否可以使用 WiX DTF 类获取组件代码？（或任何其他方式来实现...）

我不理解为“产品”获得“组件”的愿望，因为这不是 1:1 的关系。也就是说，这可以满足您的要求：

const string PRODUCT_CODE = "{EBBD327E-F220-4567-88F8-CEE3BE560F81}";
var comps = from c in ComponentInstallation.AllComponents
            where c.Product.ProductCode == PRODUCT_CODE
            select c;
string componentId = comps.FirstOrDefault().ComponentCode;

我发现可以使用以下方法获取组件代码：

private string GetComponentIdFromMsi()
{
    using (Session product = Installer.OpenProduct(_productCode))
    using (Database database = product.Database)
    {
        var featureComponentsRecords = GetFeatureComponents(database);
        var featureComponentsRecord = featureComponentsRecords.Single(x => x.Feature == _feature);
        var componentRecords = GetComponents(database);
        var componentId = componentRecords.Single(x => x.Component == featureComponentsRecord.Component).ComponentId;
        return componentId;
    }
}

private IEnumerable<FeatureComponentsRecord> GetFeatureComponents(Database database)
{
    var list = database.ExecuteQuery("SELECT `Feature_`, `Component_` FROM `FeatureComponents`");
    const int columnCount = 2;
    const int featureOffset = 0;
    const int componentOffset = 1;
    int rowCount = list.Count / columnCount;

    for (int rowIndex = 0; rowIndex < rowCount; rowIndex++)
    {
        var rowOffset = rowIndex * columnCount;
        yield return new FeatureComponentsRecord((string)list[rowOffset + featureOffset], (string)list[rowOffset + componentOffset]);
    }
}

private IEnumerable<ComponentRecord> GetComponents(Database database)
{
    var list = database.ExecuteQuery("SELECT `Component`, `ComponentId` FROM `Component`");
    const int columnCount = 2;
    const int componentOffset = 0;
    const int componentIdOffset = 1;
    int rowCount = list.Count / columnCount;

    for (int rowIndex = 0; rowIndex < rowCount; rowIndex++)
    {
        var rowOffset = rowIndex * columnCount;
        yield return new ComponentRecord((string)list[rowOffset + componentOffset], (string)list[rowOffset + componentIdOffset]);
    }
}

private class FeatureComponentsRecord
{
    public FeatureComponentsRecord(string feature, string component)
    {
        Feature = feature;
        Component = component;
    }

    public string Feature { get; private set; }
    public string Component { get; private set; }
}

private class ComponentRecord
{
    public ComponentRecord(string component, string componentId)
    {
        Component = component;
        ComponentId = componentId;
    }

    public string Component { get; private set; }
    public string ComponentId { get; private set; }
}
