c# WPF - 文件访问被拒绝

Question

我正在尝试通过 InstallShield 为我的 wpf soln 创建一个 msi 文件，在这个 WPF soln 中我正在尝试使用以下代码访问 .rtf 文件：

 string rtfFilePath = @"Help.rtf";

using (var fs = new FileStream(rtfFilePath, FileMode.Open)){ ... }

在调试模式下它工作正常但是当我已经创建了一个 msi 文件和运行 msi 文件并将它安装在我的机器上到 C:/Program Files/Company_Name/Project_Name 的路径并启动exe 程序文件与 rtf 文件位于同一 directory/folder exe 文件所在的位置。

我收到 "Access to the path 'C:/Program Files/Company_Name/Project_Name\Help.rtf' is denied."

的异常消息

到目前为止我错过了什么？

访问 Program Files 需要管理员权限，因此您必须运行您的程序作为管理员。

您可以让您的程序在运行ning 时需要管理员权限，为此请参阅以下问题： How do I force my .NET application to run as administrator?

P.S.: 请注意，如果可能的话，您可以避免访问 Program Files 等限制区域，然后您就不需要授予此权限。
