How to fetch all list titles in editor part of web part?

Question

I want to fetch all the list titles of the current site in a dropdown in my web part's editor part. Based on this selection I want to show list items in web part when Apply is hit.

My web part is deployed at site collections level.

Answer 1

Get the List title source:

public static IList<String> GetAllListTitle(SPWeb web)
{
    List<String> title = new List<String>();

    foreach(SPList list in web.Lists)
      title.Items.Add(list.Title)
}

Have a look at these for how to implement dynamic dropdown as webpart property.

Answer 2

Use this code to populate the dropdown list.

    SPWeb web = SPContext.Current.Web;
    foreach(SPList list in web.Lists)
    {
    dropdownList.Items.Add(list.Title)
    }
