代码已经创建,但是给了我一个小错误。这是用于在第一个登录页面中保存用户名的代码。
public void SaveSetting(string userLabel, string userNamelabel)
{
ApplicationDataContainer localSettings =
ApplicationData.Current.LocalSettings;
//Saving your setting
localSettings.Values[userLabel] = textBoxUsername.Text;
}
我的主页上
public home()
{
this.InitializeComponent();
UserNameLabelBox.Text = ReadSetting(userLabel);
}
private string ReadSetting(string userLabel)
{
Windows.Storage.ApplicationDataContainer localSettings =
Windows.Storage.ApplicationData.Current.LocalSettings;
//Reading and returning your setting value
var value = localSettings.Values[userLabel];
if (value != null)
return value.ToString();
else
return userLabel;
初始化组件下面的行以红色突出显示,并表示“ userLabel在当前上下文中不存在”。
答案 0 :(得分:0)
似乎您从未将主页上变量userLabel
的值设置为可以从另一页看到的变量。
我将向您的登录页面添加一个名为public string globalUserLabel ;
的公共全局变量,然后在您的主页home方法中调用它。
喜欢:
public string globalUserLabel;
public void SaveSetting(string userLabel, string userNamelabel)
{
globalUserLabel = userLabel;
ApplicationDataContainer localSettings =
ApplicationData.Current.LocalSettings;
//Saving your setting
localSettings.Values[userLabel] = textBoxUsername.Text;
}
public home()
{
this.InitializeComponent();
UserNameLabelBox.Text = ReadSetting(LoginPage.globalUserLabel );
}
OR
您可以创建一个globalVariable
类,并将用户信息存储在该类中,并在必要时调用此特定类。
看起来像
public class globalVariable {
public string userlabel {get; set;};
}
然后
public void SaveSetting(string userLabel, string userNamelabel)
{
globalVariable.userlabel = userLabel;
ApplicationDataContainer localSettings =
ApplicationData.Current.LocalSettings;
//Saving your setting
localSettings.Values[userLabel] = textBoxUsername.Text;
}
最后
public home()
{
this.InitializeComponent();
UserNameLabelBox.Text = ReadSetting(globalVariable.userlabel);
}
