来自C#自定义操作的MsiSetProperty

action1如何在C#自定义操作中设置MSI属性,到目前为止,我已经有了这个,但是如何获取该句柄？

[DllImport("msi.dll", CharSet = CharSet.Unicode)]
static extern int MsiSetProperty(IntPtr hInstall, string szName, string szValue);

public void SetProperty(string propertyName, string propertyValue)
{
    MsiSetProperty(handle, propertyName, propertyValue);
}

我正在通过以下行从WiX呼叫CA

<CustomAction Id="CA1" BinaryKey="ca1.dll" DllEntry="action1" />

而action1看起来像这样

public class CustomActions
{
    [CustomAction]
    public static ActionResult action1(Session session)
    {
        session.Log("Begin action1");
        SetProperty("xyz", "123");
    }
} 

解决方法:

您应该可以通过执行以下操作来设置属性：

public class CustomActions 
{ 
    [CustomAction] 
    public static ActionResult action1(Session session) 
    { 
        string xyzProperty = "XYZ";

        session[xyzProperty] = "ABC";
    } 
}

我相信他很快就会对此发表评论.
