Below is a crude for-loop to illustrate what I need to do.
Basically, if there are any 'Variable' objects with property 'Name' containing the text "TCC#", then I want to change the 'Type' property (not the .Net type) to 'VariableType.Text'.
The code is going to run over 4800 ParsedCard variables and currently takes a stupid amount of time (about 10 minutes) to simply iterate through the list and write a line to the Debug console.
ParsedCard has
IEnumberable Functions which have
IEnumberable Groups which have
ParseResults which have
IEnumberable Variables
This is such a simple problem but I've tried all sorts of variations using LINQ but can't find anything that performs well (less than 10 seconds).
private void AdjustTCCVariables(IList parsedCards)
{
for (var i = 0; i < parsedCards.Count; i++)
{
var parsedCard = parsedCards[i];
for (var j = 0; j < parsedCard.Functions.Count(); j++)
{
var function = parsedCard.Functions.ToList()[j];
for (var k = 0; k < function.Groups.Count(); k++)
{
var group = function.Groups.ToList()[k];
for (var l = 0; l < group.ParseResult.Variables.Count(); l++)
{
var variable = group.ParseResult.Variables.ToList()[l];
if (variable.Name.Contains("TCC#"))
{
//variable.Type = VariableType.Text;
Debug.WriteLine($"Need to change variable at [{i}][{j}][{k}][{l}]");
}
}
}
}
}
}
I've tried with this LINQ but it doesn't actually change the 'variable.Type' of the input list (I suspect because it creates a new copy of the objects in memory and the assignment isn't actually affected the 'parsedCards' IEnumerable at all:
private void AdjustTCCVariables(IEnumerable parsedCards)
{
var targetVariables =
parsedCards.SelectMany(x => x.Functions.SelectMany(z => z.Groups))
.SelectMany(x => x.ParseResult.Variables.Where(v => v.Name.Contains("TCC#")));
;
foreach (var variable in targetVariables)
{
variable.Type = VariableType.Text;
}
}
