c#通过反射实现对象自动映射的实现

//第1个类 CLS1
class CLS1
{
    public int i {get; set;}
	public string str {get; set;}
}
//第2个类 CLS2
class CLS2
{
    public int i {get; set;}
	public string str {get; set;}
}

CLS1 obj1 = new CLS1(){i = 1, str = "ss"};
CLS2 obj2 = new CLS2();
//将 obj1 映射为 obj2
obj2.i = obj1.i; //obj2.i = 1; 
obj2.str = obj1.str; //obj2.str = "ss";

//将 CLS1 的对象映射为 CLS2 的对象
obj2 = Mapper.T1MapToT2<CLS1, CLS2>(obj1); //obj2.i = 1; obj2.str = "ss";

class Program
{
	static void Main()
	{
		// 创建源对象
		Person source = new Person { Name = "Alice", Age = 25 };

		// 创建目标对象
		PersonDto destination = new PersonDto();
		destination = source.MapTo<Person, PersonDto>();
		// 输出目标对象的属性值
		Console.WriteLine($"Name: {destination.Name}, Age: {destination.Age}");
	}
}

	public string Name { get; set; }
	public int Age { get; set; }

{
	public static TDest MapTo<TSource, TDest>(this TSource source) where TSource : class, new() where TDest : class, new()

		// 获取源对象的所有属性
		PropertyInfo[] sourceProperties = typeof(TSource).GetProperties();
		// 获取目标对象的所有属性
