xamarin 表单应用程序在发布和调试模式下的不同行为
Different behavior in release and debug mode in xamarin forms app
我创建了一个跨平台应用程序。
当 运行 项目处于调试模式并单击登录按钮时，它 正常工作
，但是当我设置为 释放模式 并单击登录按钮时，我收到了错误消息
这是我的登录名 xaml
<ContentPage.Content>

</ContentPage.Content>
这是我的login.xaml.cs
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class LoginPage : ContentPage
{
public LoginPage()
{
var vm = new LoginViewModel( Navigation);
this.BindingContext = vm;
vm.DisplayInvalidLoginPrompt += () => DisplayAlert("Error", "Invalid Login, try again", "OK");
InitializeComponent();
Email.Completed += (object sender, EventArgs e) =>
{
Password.Focus();
};
Password.Completed += (object sender, EventArgs e) =>
{
vm.SubmitCommand.Execute(null);
};
}
}
我使用 mvvm 模式，这是我的 mvvm
public class LoginViewModel : INotifyPropertyChanged
{
public Action DisplayInvalidLoginPrompt;
public event PropertyChangedEventHandler PropertyChanged = delegate { };
public INavigation Navigation { get; set; }
private string email;
public string Email
{
get { return email; }
set
{
email = value;
PropertyChanged(this, new PropertyChangedEventArgs("Email"));
}
}
private string password;
public string Password
{
get { return password; }
set
{
password = value;
PropertyChanged(this, new PropertyChangedEventArgs("Password"));
}
}
public ICommand SubmitCommand { protected set; get; }
//public LoginViewModel(INavigation navigation)
//{
// SubmitCommand = new Command(OnSubmit);
//}
public LoginViewModel(INavigation navigation)
{
this.Navigation = navigation;
SubmitCommand = new Command(async ()=>await OnSubmitAsync());
}
public async Task OnSubmitAsync()
{
if (email != "s" || password != "s")
{
DisplayInvalidLoginPrompt();
}
else
{
await Navigation.PushAsync(new HomePage());
}
}
在发布模式下或在实际安装后 phone，当我输入“s”和“s”（不带引号）时，它会显示我的错误消息（“无效登录，请重试”）但是在调试模式下它工作正常。
我该如何解决？
更新
这是发布
中的“调试日志 logcat”

好的，4 天后，我的解析器将我的程序集名称从混合的小写和大写更改为小写，并且每次都认为这次工作正常。
我创建了一个跨平台应用程序。 当 运行 项目处于调试模式并单击登录按钮时，它 正常工作 ，但是当我设置为 释放模式 并单击登录按钮时，我收到了错误消息 这是我的登录名 xaml

这是我的login.xaml.cs
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class LoginPage : ContentPage
{
public LoginPage()
{
var vm = new LoginViewModel( Navigation);
this.BindingContext = vm;
vm.DisplayInvalidLoginPrompt += () => DisplayAlert("Error", "Invalid Login, try again", "OK");
InitializeComponent();
Email.Completed += (object sender, EventArgs e) =>
{
Password.Focus();
};
Password.Completed += (object sender, EventArgs e) =>
{
vm.SubmitCommand.Execute(null);
};
}
}
我使用 mvvm 模式，这是我的 mvvm
public class LoginViewModel : INotifyPropertyChanged
{
public Action DisplayInvalidLoginPrompt;
public event PropertyChangedEventHandler PropertyChanged = delegate { };
public INavigation Navigation { get; set; }
private string email;
public string Email
{
get { return email; }
set
{
email = value;
PropertyChanged(this, new PropertyChangedEventArgs("Email"));
}
}
private string password;
public string Password
{
get { return password; }
set
{
password = value;
PropertyChanged(this, new PropertyChangedEventArgs("Password"));
}
}
public ICommand SubmitCommand { protected set; get; }
//public LoginViewModel(INavigation navigation)
//{
// SubmitCommand = new Command(OnSubmit);
//}
public LoginViewModel(INavigation navigation)
{
this.Navigation = navigation;
SubmitCommand = new Command(async ()=>await OnSubmitAsync());
}
public async Task OnSubmitAsync()
{
if (email != "s" || password != "s")
{
DisplayInvalidLoginPrompt();
}
else
{
await Navigation.PushAsync(new HomePage());
}
}
在发布模式下或在实际安装后 phone，当我输入“s”和“s”（不带引号）时，它会显示我的错误消息（“无效登录，请重试”）但是在调试模式下它工作正常。
我该如何解决？
更新 这是发布
