我在用mono开发crossplatform应用程序。我想检查运行应用程序的用户的rw访问权限。在NT上,我可以使用.getaccesscontrol方法(在mono-throws平台上,不支持异常),但是如何处理*nix和macos?有没有crossplatfrom的解决方案?
最佳答案
mono.unix有特定于unix的实现:
var ufi = new UnixFileInfo("/tmp/test.cpp");
ufi.CanAccess(AccessModes.F_OK); // is a file/directory
ufi.CanAccess(AccessModes.R_OK); // accessible for reading
ufi.CanAccess(AccessModes.W_OK); // accessible for writing
ufi.CanAccess(AccessModes.X_OK); // accessible for executing
FileSpecialAttributes sa = ufi.FileSpecialAttributes; //setuid, setgid and sticky bits
FileAccessPermissions fa = ufi.FileAccessPermissions;
FileAccessPermissions定义为:
[Flags ()]
public enum FileAccessPermissions {
UserReadWriteExecute,
UserRead,
UserWrite,
UserExecute,
GroupReadWriteExecute,
GroupRead,
GroupWrite,
GroupExecute,
OtherReadWriteExecute,
OtherRead,
OtherWrite,
OtherExecute,
DefaultPermissions,
AllPermissions
}
