Console.WriteLine arguments?

[TechTeach]

Hello All,

I have been researching and trying to figure out why the first WriteLine isn't printing out the entire line when I debug the code. I'm sure I am missing something really silly but I just can't figure it out. Can somebody please explain to me why the C in the first line isn't printing out when I debug ... System.Console.WriteLine("The answer is", C)

Module Module1

    Sub Main()


        Dim A As Integer = 2
        Dim B As Integer = 10
        Dim C As Integer


        Try
            C = B / A
            System.Console.WriteLine("The answer is", C)
            System.Console.WriteLine(C)
            System.Console.WriteLine("Press Enter to continue...")
            Console.ReadLine()
        Catch e As OverflowException
            System.Console.WriteLine("An overflow exception occured.")
            System.Console.WriteLine("Press Enter to continue...")
            System.Console.ReadLine()
        End Try


    End Sub


End Module

Because that overload of WriteLine takes a format string and values to insert into that format string. Your format string contains no parameter place-holders so the value you specify will not be inserted into it. That code should keep using the same overload and include a place-holder to replace with the value:

Console.WriteLine("The answer is {0}.", C)

or it should use a different overload that simply takes a single string to be output as is:

Console.WriteLine("The answer is " & C & ".")
