如何从对象中获得属性和值的名称，并将此名称和值传递给c#中的列表?

Question

我想从对象中获取属性名称和值，并将它们传递给列表。我不想一个接一个的属性和值传递到列表，就像我的代码中注释的那样。想要使用循环并动态添加名称和值

public class ParametersList
{
public string Name { get; set; }
public dynamic Value { get; set; }
}
public class BookVM
{

public string AuthorName{ get; set; }

public string CoverUrl { get; set; }
public int AuthorIds { get; set; }
}
public List<Book> Addgetallbooks(BookVM BookVM)
{
List<ParametersList> obj = new List<ParametersList>();

//List<ParametersList> obj = new List<ParametersList>
//{
//    new ParametersList{Name=nameof(BookVM.AuthorIds),Value=BookVM.AuthorIds},
//    new ParametersList{Name=nameof(BookVM.AuthorName),Value=BookVM.AuthorName},
//    new ParametersList{Name=nameof(BookVM.CoverUrl),Value=BookVM.CoverUrl}
//};
var getdata = _opr.GetBooks1(obj);
return getdata;
}

您需要使用反射，但不确定是否应该这样做:)

[TestMethod]
public void Foo()
{
var book = new BookVM() { AuthorIds = 1, AuthorName = "some name", CoverUrl = "some cover url" };
var result = GetParameters(book);
result.Should().BeEquivalentTo(new[]
{
new ParametersList { Name = nameof(BookVM.AuthorIds), Value = 1 },
new ParametersList() { Name = nameof(BookVM.AuthorName), Value = "some name" },
new ParametersList { Name = nameof(BookVM.CoverUrl), Value = "some cover url" }
});
}
private static List<ParametersList> GetParameters(BookVM book)
{
return typeof(BookVM).GetProperties().Select(p => new ParametersList
{
Name = p.Name, Value = p.GetValue(book)
}).ToList();
}
