C＃：Reflection：子類的訪問屬性

Question

我想通過反射訪問子類的屬性。但這不起作用。我怎樣才能訪問子類的所有屬性？

這是我嘗試通過反射訪問子類屬性的類。 我試過類結構抽象和部分，但都沒有工作。

public abstract class FakeDbContext 
{ 
    public FakeDbSet<T> Set<T>() where T : class, IObjectState 
    { 
     foreach (PropertyInfo property in GetType().GetProperties()) 
     { 
      if (property.PropertyType == typeof(FakeDbSet<T>)) 
       return property.GetValue(this, null) as FakeDbSet<T>; 
     } 
     throw new Exception("Type collection not found"); 
    } 
} 

子類與參數

public class MockDbContext : FakeDbContext 
{ 
    private FakeDbSet<Address> Addresses { get; set; } 
    private FakeDbSet<EmailAddress> EmailAddresses { get; set; } 
    private FakeDbSet<PhoneNumber> PhoneNumbers { get; set; } 
    private FakeDbSet<BaseContact> Contacts { get; set; } 
    private FakeDbSet<Environment> Environments { get; set; } 
    private FakeDbSet<Data.Entities.InformationService> InformationServices { get; set; } 
    private FakeDbSet<UserEnvironmentConfiguration> UserEnvironmentConfigurations { get; set; } 
    private FakeDbSet<Customer> Customers { get; set; } 
    private FakeDbSet<UserEnvironmentConfigurationSet> UserEnvironmentConfigurationSets { get; set; } 

    public MockDbContext() 
    { 
     Addresses = new FakeDbSet<Address>(); 
     EmailAddresses = new FakeDbSet<EmailAddress>(); 
     PhoneNumbers = new FakeDbSet<PhoneNumber>(); 
     Contacts = new FakeDbSet<BaseContact>(); 
     Environments = new FakeDbSet<Environment>(); 
     InformationServices = new FakeDbSet<Data.Entities.InformationService>(); 
     UserEnvironmentConfigurations = new FakeDbSet<UserEnvironmentConfiguration>(); 
     Customers = new FakeDbSet<Customer>(); 
     UserEnvironmentConfigurationSets = new FakeDbSet<UserEnvironmentConfigurationSet>(); 

     InitData(); 
    } 
}

要得到你需要使用的GetProperties超載這需要BindingFlags作爲參數來使用BindingFlags.NonPublic私人性質。

foreach (PropertyInfo property in GetType().GetProperties(BindingFlags.Instance | BindingFlags.NonPublic)) 
{ 
    ... 
}
