按名称 C# 对对象属性列表进行排序

Question

I have an object which contains many properties of type string and whose name consists of a text and number like Property1 , Property3 , Property12 ... etc.

I want to get a sorted list (OrderByDescending) of properties whose value is not null.

This means the property at the first position the should be the the property whose number (not the value) which is a part of name is highest.

For Example: In the case that the list contains objects with following properties:

(Property Name: Value)

1. Property1: 3
2. Property2: null
3. Property3: 2
4. Property4: null

This should be the sorted list that I need:

1. Property3: 2
2. Property1: 3

Here is what I tried but it doesn't work:

var objectType= typeof(Type);
var result = objectType.GetProperties()
    .Where(p => p.Name.Contains("Property") && p.GetValue(object) != null);
    .OrderByDescending(p => p.Name);

Please can you help me to realize it?

Thanks!

Answer 1

This is how I solved my problem:

creating a method public int GetNumberFromName(string name) { ... } that I can then use to sort my object list like this: .OrderByDescending(p => GetNumberFromName(p.Name));

Thanks for your help!

You could try orderby after Where clause:

var objectType= typeof(Type);
var result = objectType.GetProperties()
    .Where(p => p.Name.Contains("Property") && p.GetValue(triangleView) != null)
    .OrderBy(c => c.Name);
