为什么我的卸载方法不会被调用？ [英] Why is my Uninstall method not being called?

问题描述

2008年我国VS创建安装程序不会调用覆盖卸载方法，在我的安装程序类。为什么？该安装方法被调用。 我的安装程序类看起来是这样的：

My VS 2008 created installer doesn't call the override Uninstall method in my installer class. why? The Install method was called. My installer class looks like this:

[RunInstaller(true)]
    public partial class InstallerClass : Installer
    {
        public InstallerClass()
        {
            InitializeComponent();
        }
        public override void Install(IDictionary stateSaver)
        {
            base.Install(stateSaver);

            //encrypt connection string
            encryptConntStr();

            //create database
            createDatabase();
        }

        public override void Commit(IDictionary savedState)
        {
            base.Commit(savedState);
        }

        public override void Rollback(IDictionary savedState)
        {
            base.Rollback(savedState);
        } 

        public override void Uninstall(IDictionary savedState)
        {
            base.Uninstall(savedState);
            System.Diagnostics.Debugger.Break();
            MessageBox.Show("I am in Uninstall now.");
            string exePathStr = Context.Parameters["targetdir"];
           ...           

        }
}

推荐答案

确认CustomActionData属性不为空。有些是怎么回事空在我的情况，并会导致问题。

make sure the CustomActionData property is not empty. Some how it was empty in my case and cause that problem.
