VB -> C#: Incorrect conversion of parameterized property assignment with `=-` operator

[nabrezzelt]

VB.Net input code

_obj.ParameterizedProperty("bla") =- 1

Erroneous output

_obj.get_ParameterizedProperty("bla");

Expected output

_obj.set_ParameterizedProperty("bla", _obj.get_ParameterizedProperty("bla") - 1);

Details

• Product in use: VS extension
• Version in use: 9.2.7.0 (but not 100% sure)
• Did you see it working in a previous version, which? no
• Any other relevant information to the issue, or your interest in contributing a fix.
  ParameterizedProperty is a Property with multiple parameters

I've checked other cases where an assignment operator with a parameterized property was used in my codebase, and this seems to be the only case where this was not converted correctly... but I don't think I can give accurate reproducibility information :/

In the web converter, I've tried your suggest input, as well as a small program containing it.
I've tried it both with -= and with =- and received something that works, though not exactly your expected output

Here's what I tried:

Imports System

Public Class MyClass

    Private Shared _obj As New SomeOtherClass()

    ' Static Main method to demonstrate the decrement
    Public Shared Sub Main()
        Console.WriteLine($"Initial value of 'bla': {_obj.ParameterizedProperty("bla")}")

        ' Call it multiple times to show the decrement
        _obj.ParameterizedProperty("bla") -= 1
        Console.WriteLine($"After first decrement: {_obj.ParameterizedProperty("bla")}")

        _obj.ParameterizedProperty("bla") -= 1
        Console.WriteLine($"After second decrement: {_obj.ParameterizedProperty("bla")}")
    End Sub

End Class

Public Class SomeOtherClass

    Private _myDictionary As New Dictionary(Of String, Integer)

    Default Public Property ParameterizedProperty(ByVal key As String) As Integer
        Get
            If _myDictionary.ContainsKey(key) Then
                Return _myDictionary(key)
            Else
                ' Initialize with a default value if the key doesn't exist
                Return 10 ' Start with 10 for a clearer demonstration
            End If
        End Get
        Set(ByVal value As Integer)
            _myDictionary(key) = value
        End Set
    End Property

End Class
