在基類

Question

下面鏈接的懶方法獲取繼承的類名的C＃小提琴 https://dotnetfiddle.net/4QTGx3

我試圖在基類的靜態方法來檢索繼承的類名。沒有我找到的幫助。

public class Worker 
{ 
    public string Id1 {get; set;} 
    public string Id2 {get; set;} 
    public string Id3 {get; set;} 
} 

public interface IModel 
{ 
} 

public class Model1: IModel 
{ 
} 

public class Model2: IModel 
{ 
} 

public class ModelActor <TModel> where TModel: IModel 
{ 
    private Lazy<Worker> _worker = new Lazy<Worker>(
     () => new Worker() 
     { 
      Id1 = new StackFrame().GetMethod().DeclaringType.Name, 
      Id2 = MethodBase.GetCurrentMethod().DeclaringType.Name, 
      Id3 = typeof(ModelActor <TModel>).Name 
     } 
    ); 

    public Worker Worker 
    { 
     get 
     { 
      return _worker.Value; 
     } 
    } 
} 

public class ModelActor1: ModelActor<Model1> 
{ 
} 

public class ModelActor2: ModelActor<Model2> 
{ 
} 

public static void Main() 
{ 
    Console.WriteLine("Id1: {0} {1}", new ModelActor1().Worker.Id1, new ModelActor2().Worker.Id1); 
    Console.WriteLine("Id2: {0} {1}", new ModelActor1().Worker.Id2, new ModelActor2().Worker.Id2); 
    Console.WriteLine("Id3: {0} {1}", new ModelActor1().Worker.Id3, new ModelActor2().Worker.Id3); 

    Console.WriteLine("Want to get: ModelActor1 ModelActor2"); 
}

好吧修好了。您需要實際添加第二個ModelActor類，因爲只有一個簽名被調用。

using System; 
using System.Reflection; 
using System.Diagnostics; 

public class Program 
{ 

public class Worker 
{ 
    public string Id1 {get; set;} 
    public string Id2 {get; set;} 
    public string Id3 {get; set;} 

    public string ModelName {get; set;} 
} 

public interface IModel 
{ 
} 

public class Model1: IModel 
{ 
} 

public class Model2: IModel 
{ 
} 

public class ModelActor <TModel> where TModel: IModel 
{ 
    private Lazy<Worker> _worker = new Lazy<Worker>(
     () => { 
       Console.WriteLine("Worker Instance created"); 

       return new Worker() 
       { 
        Id1 = new StackFrame().GetMethod().DeclaringType.Name, 
        Id2 = MethodBase.GetCurrentMethod().DeclaringType.Name, 
        Id3 = typeof(ModelActor <TModel>).Name, 

        ModelName = typeof(TModel).Name 
       }; 
     } 
    ); 

    public Worker Worker 
    { 
     get 
     { 
      return _worker.Value; 
     } 
    } 
} 


public class ModelActor2 <TModel> where TModel: IModel 
{ 
    private Lazy<Worker> _worker = new Lazy<Worker>(
     () => { 
       Console.WriteLine("Worker Instance created"); 

       return new Worker() 
       { 
        Id1 = new StackFrame().GetMethod().DeclaringType.Name, 
        Id2 = MethodBase.GetCurrentMethod().DeclaringType.Name, 
        Id3 = typeof(ModelActor <TModel>).Name, 

        ModelName = typeof(TModel).Name 
       }; 
     } 
    ); 

    public Worker Worker 
    { 
     get 
     { 
      return _worker.Value; 
     } 
    } 
} 

public class ModelActor1: ModelActor<Model1> 
{ 
} 

public class ModelActor2: ModelActor2<Model2> 
{ 
} 

public static void Main() 
{ 
    Console.WriteLine("Id1: {0} {1}", new ModelActor1().Worker.Id1, new ModelActor2().Worker.Id1); 
    Console.WriteLine("Id2: {0} {1}", new ModelActor1().Worker.Id2, new ModelActor2().Worker.Id2); 
    Console.WriteLine("Id3: {0} {1}", new ModelActor1().Worker.Id3, new ModelActor2().Worker.Id3); 

    Console.WriteLine("Want to get: ModelActor1 ModelActor2\n"); 

    Console.WriteLine("ModelName: {0} {1}", new ModelActor1().Worker.ModelName, new ModelActor2().Worker.ModelName); 
    Console.WriteLine("No problem with model name."); 
} 
}
