I'm trying to iterate through an array of objects and recursively print out each objects properties.
Here is my object model:
type firmIdentifier = {
firmId: int ;
firmName: string ;
}
type authorIdentifier = {
authorId: int ;
authorName: string ;
firm: firmIdentifier ;
}
type denormalizedSuggestedTradeRecommendations = {
id: int ;
ticker: string ;
direction: string ;
author: authorIdentifier ;
}
Here is how I am instantiating my objects:
let getMyIdeasIdeas = [|
{id=1; ticker="msfqt"; direction="buy";
author={authorId=0; authorName="john Smith"; firm={firmId=12; firmName="Firm1"}};};
{id=2; ticker="goog"; direction="sell";
author={authorId=1; authorName="Bill Jones"; firm={firmId=13; firmName="ABC Financial"}};};
{id=3; ticker="DFHF"; direction="buy";
author={authorId=2; authorName="Ron James"; firm={firmId=2; firmName="DEFFirm"}};}|]
And here is my algorithm to iterate, recurse and print:
let rec recurseObj (sb : StringBuilder) o=
let props : PropertyInfo [] = o.GetType().GetProperties()
sb.Append( o.GetType().ToString()) |> ignore
for x in props do
let getMethod = x.GetGetMethod()
let value = getMethod.Invoke(o, Array.empty)
ignore <|
match value with
| :? float | :? int | :? string | :? bool as f -> sb.Append(x.Name + ": " + f.ToString() + "," ) |> ignore
| _ -> recurseObj sb value
for x in getMyIdeas do
recurseObj sb x
sb.Append("\r\n") |> ignore
If you couldnt tell, I'm trying to create a csv file and am printing out the types for debugging purposes. The problem is, the first element comes through in the order you'd expect, but all subsequent elements come through with a slightly different (and confusing) ordering of the "child" properties like so:
RpcMethods+denormalizedSuggestedTradeRecommendationsid:
1,ticker: msfqt,direction:
buy,RpcMethods+authorIdentifierauthorId:
0,authorName: john
Smith,RpcMethods+firmIdentifierfirmId:
12,firmName: Firm1,
RpcMethods+denormalizedSuggestedTradeRecommendationsid:
2,ticker: goog,direction:
sell,RpcMethods+authorIdentifierauthorName:
Bill
Jones,RpcMethods+firmIdentifierfirmName:
ABC Financial,firmId: 13,authorId: 1,
RpcMethods+denormalizedSuggestedTradeRecommendationsid:
3,ticker: DFHF,direction:
buy,RpcMethods+authorIdentifierauthorName:
Ron
James,RpcMethods+firmIdentifierfirmName:
DEFFirm,firmId: 2,authorId: 2,
Any idea what is going on here?
