推荐答案

类自定义操作是应该System.Configuration.Installer.Installer继承。这有一个参数，它叫做语境其中有一个参数字典。这本词典包含了一些关于安装，你可以添加一些有用的变量。

The class your custom action is in should inherit from System.Configuration.Installer.Installer. This has a parameter on it called Context which has a Parameters dictionary. The dictionary contains a number of useful variables about the install and you can add some.

一旦你添加的自定义安装程序中的自定义操作你的痛苦安装项目。选择安装操作和CustomActionData属性设置为：

Once you have added the custom installer to your install project in the Custom Actions pain. Select the Install action and set the CustomActionData property to:

/targetdir="[TARGETDIR]\"

然后就可以像这样访问路径：

Then you can access the path like this:

[RunInstaller(true)]
public partial class CustomInstaller : System.Configuration.Install.Installer
{
    public override void Install(System.Collections.IDictionary stateSaver)
    {
        base.Install(stateSaver);
        string path = this.Context.Parameters["targetdir"]; 
        // Do something with path.
    } 
}
