Run Code Online (Sandbox Code Playgroud) 我想编写一个用于插入和更新mongodb数据的长脚本.
我有一节课:
class A {
public string a = "A-val" , b = "B-val";
}
Run Code Online (Sandbox Code Playgroud)
我想通过反射打印对象成员
//Object here is necessary.
Object data = new A();
FieldInfo[] fields = data.GetType().GetFields();
String str = "";
foreach(FieldInfo f in fields){
str += f.Name + " = " + f.GetValue(data) + "\r\n";
}

这是期望的结果:
a = A-val
b = B-val

不幸的是,这不起作用.请帮忙,谢谢.

我该怎么写一个方法并返回7?
我希望在没有列表,地图或其他助手的帮助下保持原生.只有数组[].
我试图用多级成员映射对象:这些是类:
public class Father
{
public int Id { get; set; }
public Son Son { get; set; }
}
public class FatherModel
{
public int Id { get; set; }
public int SonId { get; set; }
}
public class Son
{
public int Id { get; set; }
}

这是我尝试自动化它的方式:
AutoMapper.Mapper.CreateMap<FatherModel , Father>()
.ForMember(dest => dest.Son.Id, opt => opt.MapFrom(src => src.SonId));
Run Code Online (Sandbox Code Playgroud)
这是我得到的例外:
表达式'dest => Convert(dest.Son.Id)'必须解析为顶级成员而不是任何子对象的属性.请在子类型或AfterMap选项上使用自定义解析程序.参数名称:lambdaExpression
谢谢

但是, ReferenceLoopHandling 内部不可用options.JsonSerializerOptions。

我在我的开发机器上有一个需要证书的WCF客户端,它工作正常.

即使网络之间没有密码也没有证书密码.(我知道因为开发工作没有密码).我唯一的密码是WCF,它与DEV相同.
