最快的映射对象的方法 [英] Fastest way of mapping objects

问题描述

C＃.Net：

我有一个大对象，其中包含20个属性的复杂映射和38个属性的简单映射，目前我使用反射映射这些，但我仍然需要在性能方面有所改进映射。



任何人都可以建议哪个库最好提高映射性能？



我尝试了什么：



i尝试使用自动播放器以及手动映射属性。

我们还需要改进性能。

我当前的实现：

C# .Net :
I have big object which contains complex mapping with 20 properties and simple mapping with 38 properties ,Currently i'm mapping these using reflection but still i need a performance improvement in my mapping.

Can any one suggest which library is best to improve the mapping performance?

What I have tried:

i tried with automapper and also manual mapping of properties.
still we need improvement in performance.
My current implementation:

public void FillObjectFromData(object objectToFill, object fromData)
		{
			if (fromData != null)
			{
				System.Reflection.PropertyInfo[] contractProperties = (objectToFill.GetType()).GetProperties();
				foreach (System.Reflection.PropertyInfo contractProperty in contractProperties)
				{
					if (contractProperty.CanWrite && fromData.GetType().GetProperty(contractProperty.Name) != null)
					{
						try
						{
							object dataValue = fromData.GetType().GetProperty(contractProperty.Name).GetValue(fromData, null);
							if ((dataValue != null) || (contractProperty.PropertyType.IsGenericType && contractProperty.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>)))
							{
								contractProperty.SetValue(objectToFill, dataValue, null);
							}
						}
						catch //(Exception ex)
						{

						}
					}
				}
			}
		}

推荐答案

我的建议也是跳过所有映射。您可以通过简单地定义接口并传递它们来轻松隐藏属性。例如，您收到 Abcde ，但将其作为 IAbc 传递，这有效地限制了对某些属性的访问。

My advice would also be to skip all that mapping. You can easily hide properties by simply defining interfaces and pass those. For example, you receive Abcde but pass it as IAbc which effectively restricts access to some properties.

public interface IAbc 
{
  int A { get; }
  int B { get; }
  int C { get; }
}

public class Abcde : IAbc
{
  public int A { get; set; }
  public int B { get; set; }
  public int C { get; set; }
  public int D { get; set; }
  public int E { get; set; }
}

祝你好运！
