Integer.TryParse – a better way?

No need to declare the integer.

If Integer.TryParse(intToCheck, 0) Then

or

If Integer.TryParse(intToCheck, Nothing) Then

If you have .Net 3.5 ability you can create an extension method for strings.

Public Module MyExtensions

    <System.Runtime.CompilerServices.Extension()> _
    Public Function IsInteger(ByVal value As String) As Boolean
        If String.IsNullOrEmpty(value) Then
            Return False
        Else
            Return Integer.TryParse(value, Nothing)
        End If
    End Function

End Module

And then call like:

If value.IsInteger() Then

Sorry, getting carried away I know, but also you can add this to the MyExtensions class above in .Net 3.5 and not worry unless you need validations.

<System.Runtime.CompilerServices.Extension()> _
Public Function ToInteger(ByVal value As String) As Integer
    If value.IsInteger() Then
        Return Integer.Parse(value)
    Else
        Return 0
    End If
End Function

Then simply use

value.ToInteger()

This will return 0 if it isn’t a valid Integer.
