推荐答案

根据您的需要，有多种方法.应用程序开发人员对 UAC 的要求 中提供了一些详细信息.>

There are a number of methods depending on your needs. Some details are given in the application developer requirements for UAC.

1. 包含一个 UAC 清单，使您的程序在启动时需要管理员权限.
2. 使用建议的方法之一调用提升以运行进程.最好的方法之一是使用 COM 提升绰号 和 CoCreateInstanceAsAdmin 在以管理员身份运行的 COM 对象上调用方法.这可能很难在 VB.Net 中工作.我在 C++ 中运行正常
3. 另一种可行的方法是将需要管理员权限的代码部分隔离到使用 UAC 清单以要求管理员权限的应用程序中.在这种情况下，您的主应用程序不需要以管理员身份运行.当您需要管理员权限时，您将调用外部应用程序.

1. Include a UAC manifest that causes your program to require administrator privileges at startup.
2. Use one of the suggested methods for invoking an elevation to run out of process. One of the nicest is to use the COM elevation moniker and CoCreateInstanceAsAdmin to call methods on a COM object running as an administrator. This is possibly tricky to get working in VB.Net. I got it working ok in C++ though
3. Another ok method is to isolate the parts of your code that need admin privileges into an application that uses a UAC manifest to require admin privileges. Your main app does not need to run as an admin in that case. When you require admin privilegese, you would invoke the external application.
