使用C#以编程方式卸载软件

问题描述

我想使用我的代码卸载软件，我已经尝试使用wmic方法执行卸载，但是它无法在系统中找到我的软件.是否可以不使用msi文件或任何安装文件进行卸载.我找到了此代码，但它不起作用---

I want to uninstall a software by using my code, I have already tried wmic approach to perform uninstallation but it can't able to find my Software in the system. Is it possible to uninstall without using msi file or any setup file. I found this code but it doesn't work---

public string GetUninstallCommandFor(string productDisplayName)
{
    RegistryKey localMachine = Registry.LocalMachine;
    string productsRoot = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products";
    RegistryKey products = localMachine.OpenSubKey(productsRoot);
    string[] productFolders = products.GetSubKeyNames();

    foreach (string p in productFolders)
    {
        RegistryKey installProperties = products.OpenSubKey(p + @"\InstallProperties");
        if (installProperties != null)
        {
            string displayName = (string)installProperties.GetValue("DisplayName");
            if ((displayName != null) && (displayName.Contains(productDisplayName)))
            {
                string uninstallCommand = (string)installProperties.GetValue("UninstallString");
                return uninstallCommand;
            }
        }
    }
    return "";
}

推荐答案

最可靠的方法是以编程方式执行以下shell命令:

The most reliable way would be to programmatically execute the following shell command:

msiexec.exe /x {PRODUCT-GUID}

如果您制作的是原始MSI，则可以访问PRODUCT-GUID，这就是您所需要的.完全不需要MSI文件，因为Windows完全出于此目的将它的副本藏起来了.

If you made the original MSI you will have access to your PRODUCT-GUID, and that is all you need. No need for the actual MSI file as Windows stashes a copy of this away for exactly this purpose.
