问题描述

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？

action1How do I set a MSI property from within a C# custom action, so far I have this but how do I get the handle?

[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

I am calling the CA from WiX with the following line

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

action1看起来像这样

and the action1 looks like this

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

推荐答案

您应该可以通过执行以下操作来设置属性：

You should be able to set a property by doing the following:

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

        session[xyzProperty] = "ABC";
    }
}
