Question

我有一堆这样的代码：

public class Customer : Person
{
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd hh:MM:ss}")]
    [Display(Name = "Create Date")]
    public DateTime CreateDate { get; set; }
    public Status Status { get; set; }

    public virtual ICollection<Note> Notes { get; set; }
}

和我尝试致电时的另一个页面

    @model Demo.Models.Customer

    @Html.TextAreaFor(model => model.Notes.)

我无法获得model.Note.Message

我想将其与客户绑定在同一页面中当它显示客户详细信息并能够在同一页面中添加客户的注释时，我会尝试执行的操作。任何想法？非常感谢

您的方法无效，因为您的import UIKit class ViewController: UIViewController { @IBOutlet weak var textLabel: UILabel! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. textLabel.numberOfLines = 0 textLabel.lineBreakMode = .byWordWrapping let myShadow = NSShadow() myShadow.shadowBlurRadius = 3 myShadow.shadowOffset = CGSize(width: 3, height: 3) myShadow.shadowColor = UIColor.gray let attributedText = NSMutableAttributedString(string: "") let fatString = NSMutableAttributedString(string: "Bold", attributes: [NSAttributedString.Key.foregroundColor : UIColor.green, NSAttributedString.Key.font : UIFont.boldSystemFont(ofSize: 16), NSAttributedString.Key.backgroundColor : UIColor.lightGray, NSAttributedString.Key.shadow : myShadow]) let normalString = NSAttributedString(string: "\n\nNormal", attributes: [NSAttributedString.Key.foregroundColor : UIColor.white, NSAttributedString.Key.font : UIFont.systemFont(ofSize: 16)]) let italicString = NSAttributedString(string: "\n\nItalic", attributes: [NSAttributedString.Key.foregroundColor : UIColor.yellow, NSAttributedString.Key.font : UIFont.italicSystemFont(ofSize: 16)]) let otherFontString = NSAttributedString(string: "\n\nBold + Italic", attributes: [NSAttributedString.Key.foregroundColor : UIColor.gray, NSAttributedString.Key.font : UIFont(descriptor: UIFontDescriptor().withSymbolicTraits([.traitBold, .traitItalic])!, size: 16)]) let normalString2 = NSAttributedString(string: "\n\nUnderlined", attributes: [NSAttributedString.Key.underlineStyle : NSUnderlineStyle.single.rawValue, NSAttributedString.Key.foregroundColor : UIColor.red, NSAttributedString.Key.font : UIFont.systemFont(ofSize: 16)]) attributedText.append(fatString) attributedText.append(normalString) attributedText.append(italicString) attributedText.append(otherFontString) attributedText.append(normalString2) textLabel.attributedText = attributedText } }是一个不包含model.Notes对象的集合。根据您的要求，您可以尝试Message或遍历model.Notes.First().Message并为每个便笺创建文本框。

model.Notes

您可以尝试吗？

@foreach(var note in Model.Notes)
{
    @Html.TextArea(note.Message)
}
