How to add item when using List (Of)?

Question

I created a class where i declared some properties.

Public Class BlogPost

    Dim _postTitleUrl As String = String.Empty
    Dim _pageGUID As String = String.Empty


    Property postTitleUrl() As String
        Get
            Return _postTitleUrl
        End Get
        Set(ByVal value As String)
            _postTitleUrl = value
        End Set
    End Property
    Property pageGUID() As String
        Get
            Return _pageGUID
        End Get
        Set(ByVal value As String)
            _pageGUID = value
        End Set
    End Property
End Class

Now, I have another class where I want to set the values.

Public Class SetBlogData

  Public blogPostList As New List(Of BlogPost)
  Public dataCounter as integer = 0

  blogPostList(dataCounter).pageGUID = mainBlogSPWeb.ID.ToString

....

This gives me an error about Index was out of range. Hpw can I properly access the properties in BlogPost class?

Answer 1

Because your list has nothing .

You should use add method to add your new item. Like ...

        Dim blogPostList = New List(Of BlogPost)
        Dim blogPost = New BlogPost
        blogPost.pageGUID = mainBlogSPWeb.ID.ToString
        blogPostList.Add(blogPost)

Answer 2

You need to put a BlogPost in your list by writing blogPost.List.Add(New BlogPost())
