How would I sort a list of objects?
For example,

C#

List<someobject> list = new List<someobject>();
list.add(someObject) 100 times

Now there is

C#

someObject.someDoubleValue = .232;

Each someObject has a someDoubleValue property which holds a double value.

Now, I want to sort the list based on someObject.someDoubleValues so the list would be

C#

list[0] = someobject1.someDoubleValue =.2
list[1] = someObject2.someDoubleValue =.3
list[2] = someObject3.someDoubleValue = .4

etc in the list

Solution 2

Each someObject is an instance of some class. Implement the IComparable interface[^] for that class.

Without this, list.Sort() cannot know what order you want the list to be sorted in.
