xamarin形成共享的首选项

Question

将以下代码写入共享项目。

进口包装

using Android.Content;
using Android.Preferences;

用于将值存储到共享首选项中

ISharedPreferences pref = PreferenceManager.GetSharedPreferences("UserInfo", FileCreationMode.Private);
ISharedPreferencesEditor edit = pref.Edit();
edit.PutString("Username", username.Text.Trim());
edit.PutString("Password", password.Text.Trim());
edit.Apply();        

用于检索值

ISharedPreferences pref = PreferenceManager.GetSharedPreferences("UserInfo", FileCreationMode.Private);
string userName = pref.GetString("Username", String.Empty);
string password = pref.GetString("Password", String.Empty);

我们得到了以下错误

“ Android.Preferences.PreferenceManager”不包含“ GetSharedPreferences”的定义
