两个类重复属性值复制

核心代码

    /// <summary>
    /// 属性重复值复制
    /// </summary>
    /// <typeparam name="V">源模型</typeparam>
    /// <typeparam name="T">目标模型</typeparam>
    /// <param name="sourceList">数据源</param>
    /// <returns></returns>
    public static List<T> ConvertData<V, T>(List<V> sourceList)
    {
        List<T> list = new List<T>();
        Type type = typeof(T);
        PropertyInfo[] properties = type.GetProperties();//获取目标模型属性

        foreach (V item in sourceList)
        {
            T model = Activator.CreateInstance<T>(); //创建目标模型实例

            for (int i = 0; i < properties.Length; i++)
            {
                PropertyInfo[] personPro = item.GetType().GetProperties();
                for (int j = 0; j < personPro.Length; j++)
                {             
                    //判断目标模型的属性是不是源模型中的
                    if (properties[i].Name == personPro[j].Name && properties[i].PropertyType == personPro[j].PropertyType)
                    {
                        Object value = personPro[j].GetValue(item, null);
                        //将源模型中属性的值赋值给目标模型的属性                  
                        properties[i].SetValue(model, value, null);
                    }
                }            
            }
            list.Add(model);
        }
        return list;
    }

  测试:

      类Test1

    public string ID { get; set; }
    public string Name { get; set; }
    public string Sex { get; set; }
    public string Address { get; set; }

  类Test2

    public string ID { get; set; }
    public string Name { get; set; }
    public string Sex { get; set; }

  调用

        List<Test1> testList = new List<Test1>
            {
                new Test1
                {
                    ID = "1", Name = "王二狗", Sex = "男", Address="12"
                },
                new Test1
                {
                    ID = "2", Name = "王狗", Sex = "男", Address="12"
                }
            };
        List<Test2> list = new List<Test2>();

        list = ConvertData<Test1, Test2>(testList);
