如何映射两个不同对象的属性？

本文介绍了如何映射两个不同对象的属性？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我想知道如何映射两个不同对象的字段，将值赋给它I want to know how to map fields of two different objects and assign the values to it. Eample：public class employee{ public int ID { get; set; } public string Name { get; set; }}public class manager{ public int MgrId { get; set; } public string MgrName { get; set; }}现在我有一个List对象。我想要的值分配给经理级。任何自动的方式来做到这一点。我能做到这一点，并明确地给它赋值。但我的目标是，多数民众赞成这个问题非常巨大的。我不想使用任何第三方工具太Now I have a List object. I want to assign the values to "manager" class. Any automatic way to do that. I can do it explicitly and assigning values to it. But my object is very huge thats the problem. I dont want to use any third party tools too. 注意：它不能有任何经理前缀。它可以是任何东西。 （例如：MGRID可以像mgrCode）推荐答案您可以使用反射它，甚至忽略了物业外壳（注意 employee.ID 与 manager.MgrId ）：You could use reflection for it, even by ignoring the property casing (notice the employee.ID vs. manager.MgrId):class Program{ static void Main(string[] args) { var employee = new Employee() { ID = 1, Name = "John" }; var manager = new Manager(); foreach (PropertyInfo propertyInfo in typeof(Employee).GetProperties()) { typeof(Manager) .GetProperty("Mgr" + propertyInfo.Name, BindingFlags.IgnoreCase | BindingFlags.Instance | BindingFlags.Public) .SetValue(manager, propertyInfo.GetValue(employee)); } }}public class Employee{ public int ID { get; set; } public string Name { get; set; }}public class Manager{ public int MgrId { get; set; } public string MgrName { get; set; }}如果您不知道经理If you don't know the Mgr prefix, you could only match by suffixes:foreach (PropertyInfo propertyInfo in typeof(Employee).GetProperties()){ typeof(Manager).GetMembers() .OfType<PropertyInfo>() .FirstOrDefault(p => p.Name.EndsWith(propertyInfo.Name, StringComparison.CurrentCultureIgnoreCase)) .SetValue(manager, propertyInfo.GetValue(employee));} 和一个很窄的和不切实际的假设：映射基于属性的订单上（如果所期望的2种类型具有相同的顺序和数量，作为属性名的唯一区别定义的属性）。我不建议在现实生活中使用它的人，不过，在这里它是（只是使它更加的脆弱的:)）：And a very narrow and impractical assumption: mapping based on the property order (if you are expecting the 2 types to have properties defined in the same sequence and number, the only difference being the property names). I wouldn't recommend anyone using it in real life, but still, here it is (just to make it more fragile :) ):typeof(Employee) .GetProperties() .Select((p, index) => new { Index = index, PropertyInfo = p }) .ToList() .ForEach(p => { typeof(Manager) .GetProperties() .Skip(p.Index) .FirstOrDefault() .SetValue(manager, p.PropertyInfo.GetValue(employee)); }); 这篇关于如何映射两个不同对象的属性？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
