获得从数据库（ASP.NET）ID

Question

我需要他的FIO得到面试官的ID

我有表有这位模特

[Key] 
    public int Interwier_id { get; set; } 
    public string FIO { get; set; } 
    public string Email { get; set; } 
    public string Telephone { get; set; } 
    [DataType(DataType.Date)] 
    public int Birthday { get; set; } 
    public string City { get; set; } 
    public string Salary { get; set; } 
    public string English { get; set; } 
    public Nullable<int> Interview_Id { get; set; } 
    public string Status { get; set; } 
    public string Position { get; set; } 
    public string Current_work { get; set; } 
    public int Age { get { return DateTime.Now.Year - Birthday; } } 
    public virtual Interview Interview { get; set; } 
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")] 
    public virtual ICollection<Link> Links { get; set; } 
    [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")] 
    public virtual ICollection<Comment> Comments { get; set; } 
} 

我得到的名称从文本字段这样

interwierName: $("#name").text()

在这里，后端代码

public ActionResult AddComment(string name,string commentText, string interwierName) 
    { 
     var Id = db.InterwierModels 
      .Where(x => x.FIO == interwierName) 
      .Select(x => new 
      { 
       ID = x.Interwier_id 
      }).FirstOrDefault(); 

     //var idForCreating = Int32.Parse(Id.ToString()); 

     Comment cmnt = new Comment() 
     { 
      Author = name, 
      Comment1 = commentText, 
      Interview_Id = Id 
     }; 
     db.Comments.Add(cmnt); 
     db.SaveChanges(); 
     return Json(new { Result = "Success", Message = "Saved Successfully" }); 
    } 

但我有这个错误

严重性代码说明项目文件的线路抑制状态 错误CS0029不能类型隐式转换：“诠释”“<匿名int类型ID>”，以SmartSolutions C：\ Users \ Eugene \ Source \ Repos \ SmartWeb \ SmartSolutions \ Controllers \ InterwierController.cs 52 Active

我该如何解决它？

Answer 1

替换此

var Id = db.InterwierModels 
      .Where(x => x.FIO == interwierName) 
      .Select(x => new 
      { 
       ID = x.Interwier_id 
      }).FirstOrDefault(); 

随着

var Id = db.InterwierModels 
       .Where(x => x.FIO == interwierName) 
       .Select(x => x.Interwier_id) 
       .FirstOrDefault();
