Question Solution builds altough there are errors

[stehtimschilf]

Hi Forum

Why does the IDE compiles this classes without any error messages?

Public Class TestClass1
    Public Shared Function test1() As String
        Return ""
    End Function
End Class

Public Class TestClass2
    Public Shared Sub test()
        Dim s As String = TestClass1.test1(2)
    End Sub
End Class

The test1()-function has no parameters! But the IDE does not complain. During run time i'll get finally the error:
System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.

If I call test1() with

TestClass1.test1("2")

I'll get an error:
Option Strict On disallows implicit conversions from 'String' to 'Integer'.

I dont get it.....?

Function test1() returns a String, and a String can be indexed as a Char array through the default Chars property, the index parameter is Integer type. TestClass1.test1(2) would be same as TestClass1.test1.Chars(2)
