如何获取此类的所有属性

public class Data
{
    public Person;
    public List<Nationality> nationality;
    public List<Passport> passport;
    public List<Family> family;
    public List<WK_Permit> Permit;
    public List<Role> role;
}

预期输出例如是

我想得到类似的东西＆＃34; DATA.PERSON.NAME＆＃34;或＆＃34; DATA.PASSPORT.NUMBER＆＃34;或者＆＃34; DATA.ROLES.HOST＆＃34; ...等所以我必须得到类名和attibuts名称

我这样做但是它不适用于课程列表

 Type parent = typeof(VSM_Data);
            FieldInfo[] children = parent.GetFields();

            for (int i = 0; i < children.Length; i++)
            {

                Type child = children[i].FieldType;

                var columnnamesChild = from t in child.GetProperties() select t.Name;
                foreach (var item in columnnamesChild)
                {
                    DragAndDrop FundDragAndDrop = new DragAndDrop();
                    FundDragAndDrop.TITLE = item;
                    FundDragAndDrop.adresse = "{{PERSON." + children[i].Name.ToUpper() + "." + item.ToUpper() + "}}";
                    FundList.Add(FundDragAndDrop);

                }

Answer 1

你可以使用Reflection：

来完成

反射;例如：

obj.GetType().GetProperties();
obj.GetType().GetMembers();

表示类型：

typeof(Foo).GetProperties();
typeof(Foo).GetMembers();

例如：

class Foo {
    public int A {get;set;}
    public string B {get;set;}
    public string Member1;
    public int Member2;
}
...

对于Fields：

        foreach(var prop in foo.GetType().GetFields()) {
            Console.WriteLine("{0}={1}", prop.Name);
        }

对于属性：

 Foo foo = new Foo {A = 1, B = "abc"};
    foreach(var prop in foo.GetType().GetProperties()) {
        Console.WriteLine("{0}={1}", prop.Name, prop.GetValue(foo, null));
    }

对于会员：

foreach(var prop in foo.GetType().GetMembers()) {
        Console.WriteLine("{0}", prop.Name);
    }

Answer 2

static void Main(string[] args)
        {

            Data data =  new Data();
            //you can use this for your case 
            var fields = data.GetType().GetFields().Select(f => f.Name);

            foreach (var f in fields)
            {
                Console.WriteLine(f);

            }
           Console.WriteLine("===");
            //but if you want a more generic one try this 
            var members = data.GetType().GetMembers().Select(m=>m.Name);
            foreach (var member in members)
            {
                Console.WriteLine(member);

            }




        }

Answer 3

此代码将为您提供所有公共属性名称

Type type = typeof(Data);
foreach (var property in type.GetProperties())
    string name = property.Name;

Answer 4

我可以找到解决方案，有时找到解决方案的最佳方法是提出问题并自己思考; - ）

Type type = typeof(VSM_Data);
            foreach (var property in type.GetFields())
            {
                FieldInfo[] children = type.GetFields();

                for (int i = 0; i < children.Length; i++)
                {

                    Type child = property.FieldType;

                    var columnnamesChild = from t in child.GetFields() select t.Name;
                    foreach (var item in columnnamesChild)
                    {
                        DragAndDrop FundDragAndDrop = new DragAndDrop();
                        FundDragAndDrop.TITLE = item;
                        FundDragAndDrop.adresse = "{{PERSON." + children[i].Name.ToUpper() + "." + item.ToUpper() + "}}";
                        FundList.Add(FundDragAndDrop);

                    }
                }
            }
