访问路径'C'被拒绝

此错误通常是因为正在尝试访问一个受保护的目录或文件而引起的。解决方法可以包括更改文件或目录的权限或提高用户的权限等。以下是一个C#代码示例，展示如何设置文件或目录的权限：

string directoryPath = @"C:\example\directory\path";
DirectoryInfo directoryInfo = new DirectoryInfo(directoryPath);

//设置文件夹的权限
DirectorySecurity directorySecurity = directoryInfo.GetAccessControl();
directorySecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
directoryInfo.SetAccessControl(directorySecurity);

//设置文件的权限
string filePath = @"C:\example\directory\path\example.txt";
FileInfo fileInfo = new FileInfo(filePath);

FileSecurity fileSecurity = fileInfo.GetAccessControl();
fileSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
fileInfo.SetAccessControl(fileSecurity);

在示例中，我们设置了“example\directory\path”和“example.txt”的权限，将“Everyone”用户组分配为完全控制的访问权限。
