sourceObject到DestinationObject的映射列表

本文关键字：映射 列表 DestinationObject sourceObject | 更新日期: 2023-09-27 18:01:41

我正在使用的代码应用属性值从一个对象到另一个相同类型的自动?

 public static class Reflection
{
    /// <summary>
    /// Extension for 'Object' that copies the properties to a destination object.
    /// </summary>
    /// <param name="source">The source.</param>
    /// <param name="destination">The destination.</param>
    public static void CopyProperties(this object source, object destination)
    {
        // If any this null throw an exception
        if (source == null || destination == null)
            throw new Exception("Source or/and Destination Objects are null");
        // Getting the Types of the objects
        Type typeDest = destination.GetType();
        Type typeSrc = source.GetType();
        // Iterate the Properties of the source instance and  
        // populate them from their desination counterparts  
        PropertyInfo[] srcProps = typeSrc.GetProperties();
        foreach (PropertyInfo srcProp in srcProps)
        {
            if (!srcProp.CanRead)
            {
                continue;
            }
            PropertyInfo targetProperty = typeDest.GetProperty(srcProp.Name);
            if (targetProperty == null)
            {
                continue;
            }
            if (!targetProperty.CanWrite)
            {
                continue;
            }
            if (targetProperty.GetSetMethod(true) != null && targetProperty.GetSetMethod(true).IsPrivate)
            {
                continue;
            }
            if ((targetProperty.GetSetMethod().Attributes & MethodAttributes.Static) != 0)
            {
                continue;
            }
            if (!targetProperty.PropertyType.IsAssignableFrom(srcProp.PropertyType))
            {
                continue;
            }
            // Passed all tests, lets set the value
            targetProperty.SetValue(destination, srcProp.GetValue(source, null), null);
        }
    }

}

这一切都很好!

我遇到的麻烦是如何创建一个类似的函数，该函数将源列表复制到目标列表，并使用它来调用上面的代码。

当然这行不通，但是像

这样
 public static void CopyListProperties(this List<object> sourceList, List<object> destinationList)
    {
        foreach (var item in sourceList)
        {
            var destinationObject = new destinationObjectType();
            item.CopyProperties(destinationObject);
            destinationList.Add(destinationObject);
        }
    }

sourceObject到DestinationObject的映射列表

感谢Alex。

函数应该是这样的。

public static void CopyListProperties<T>(this List<object> sourceList, List<T> destinationList) where T: new()
        {
            foreach (var item in sourceList)
            {
                var destinationObject = new T();
                item.CopyProperties(destinationObject);
                destinationList.Add(destinationObject);
            }
        }
