How call visual basic property getter with arguments in C# solutions

If the VB code is in a class library, then you can reference and use it like you can a C# class library.

Here is a test to show how this works:

1. Add a C# Console app to a solution
2. Add a VB class library to the solution
3. reference the VB class Library in the C# console app
4. use the following code:

VB Class Library

Public Class Class1

    Public Function GetString() As String
        Return "Hello from VB!"
    End Function

End Class

C# Console app

namespace ConsoleTest
{
    class Program
    {
        static void Main(string[] args)
        {
            var vbClass = new ClassLibrary1.Class1();

            Console.WriteLine(vbClass.GetString());
            Console.ReadKey();
        }
    }
}

5. Now compile and run and it will work. :)

** Property Test update

VB Class Library

Public Class Class1

    Public Function GetString() As String
        Return "Hello from VB!"
    End Function

    Private test As String
    Public Property TestProperty() As String
        Get
            Return test
        End Get
        Set(ByVal value As String)
            test = value
        End Set
    End Property

End Class

C# Console app

using System;

namespace ConsoleTest
{
    class Program
    {
        static void Main(string[] args)
        {
            var vbClass = new ClassLibrary1.Class1();

            // Test 1
            Console.WriteLine(vbClass.GetString());

            // Test 2
            vbClass.TestProperty = "This is a VB property test";
            Console.WriteLine(vbClass.TestProperty);

            Console.ReadKey();
        }
    }
}

Output

Hello from VB!
This is a VB property test

** Update 2: Accessing VB Property with paramater
Intellisense had the answer for you. See below:

VB Class Library

Imports System.Runtime.CompilerServices

Public Class Class1

    Public Function GetString() As String
        Return "Hello from VB!"
    End Function

    Private test As String
    Public Property TestProperty() As String
        Get
            Return test
        End Get
        Set(ByVal value As String)
            test = value
        End Set
    End Property

    Public Property Message() As String
        Get
            Return Message(Nothing, Nothing)
        End Get
        Set(value As String)
            Message(Nothing, Nothing) = value
        End Set
    End Property
    Public Property Message(useSQLInfo As Boolean?) As String
        Get
            Return Message(useSQLInfo, Nothing)
        End Get
        Set(value As String)
            Message(useSQLInfo, Nothing) = value
        End Set
    End Property

    Private flag1 As Boolean?
    Private flag2 As Boolean?
    Private messageText As String

    Public Property Message(useSQLInfo As Boolean?, manageRN As Boolean?) As String
        Get
            Return messageText
        End Get
        Set(value As String)
            messageText = value
        End Set
    End Property

End Class

C# Console app

using System;

namespace ConsoleTest
{
    class Program
    {
        static void Main(string[] args)
        {
            var vbClass = new ClassLibrary1.Class1();

            // Test 1
            Console.WriteLine(vbClass.GetString());

            // Test 2
            vbClass.TestProperty = "This is a VB property test";
            Console.WriteLine(vbClass.TestProperty);

            // test 3
            vbClass.set_Message(true, "test message");
            Console.WriteLine(vbClass.get_Message(true));

            Console.ReadKey();
        }
    }
