Store String List globally in VB.NET

how many winforms do you have?

is your String List always static?

I would probably store the info in a Config file, load it when necessary

you can also define a static class for the loading if necessary.

It is a static list . There is only one form .  Even if I keep it in config , I hope I still need some list for getting the string

if you want it to be "static" and only have one form, why not just declare it as a List (Of String) ? like:

Public Class Form1

    Dim myList As New List(Of String)

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        myList.Add("Item 1")
        myList.Add("Item 2")
        myList.Add("Item 3")
        myList.Add("Item 4")
        myList.Add("Item 5")
       
    End Sub

End Class

Select allOpen in new window

then access it like:

myList.Item(n) 

Select allOpen in new window

which n is a zero base integer.

Please use MemoryCache for this purpose. Faster for retrieval and can globally access within application domain even if you add more forms later. Add System.Runtime.Caching reference to your project.

   

 List<string> GetStringList()
        {
            var cache = MemoryCache.Default;
            var content = cache["stringList"] as List<string>;

            if (content == null)
            {
                var policy = new CacheItemPolicy
                    { AbsoluteExpiration = ObjectCache.InfiniteAbsoluteExpiration };

                content = new List<string>();
                content.Add("Item1");
                content.Add("Item2");

                cache.Set("stringList", content, policy);
            }

            return content;
        }

Select allOpen in new window

@anarki,

Just to clarify, in VB.NET a Module is the same as a static class in C#.

To the question, using a Shared member should help.
