スタックレイアウトのChildren.Add()関数に問題があります。 「SettersExtentions.Add(IList、Bindable Property、object)」の必須の仮パラメータ 'value'に対応する引数がありません。エラーは、すべての.Add単語の下に波の赤い下線です。XamarinフォームでChildren.Addを使用するとエラーが発生する
public class LoginPage : ContentPage
{
public string email { get; set; }
public string password { get; set; }
Entry emailBox = new Entry();
Entry passwordBox = new Entry();
Button createAccount = new Button();
Button forgotPassword = new Button();
Layout layout = new StackLayout();
public LoginPage()
{
Title = "Login";
emailBox.Placeholder = "email";
passwordBox.Placeholder = "password";
passwordBox.IsPassword = true;
createAccount.Text = "Create Account";
createAccount.Font = Font.SystemFontOfSize(NamedSize.Large);
createAccount.BorderWidth = 1;
createAccount.HorizontalOptions = LayoutOptions.Center;
createAccount.VerticalOptions = LayoutOptions.CenterAndExpand;
forgotPassword.Text = "Forgot Password";
forgotPassword.Font = Font.SystemFontOfSize(NamedSize.Large);
forgotPassword.BorderWidth = 1;
forgotPassword.HorizontalOptions = LayoutOptions.Center;
forgotPassword.VerticalOptions = LayoutOptions.CenterAndExpand;
layout.VerticalOptions = LayoutOptions.CenterAndExpand;
layout.Children.Add(emailBox);
layout.Children.Add(passwordBox);
layout.Children.Add(createAccount);
layout.Children.Add(forgotPassword);
Content = layout;
}
public void Check(string email, string password, string cpassword)
{
}
}
変更 'Layout Layout = new StackLayout();'を 'StackLayout layout = new StackLayout();'に変更します。 – Nkosi
