Question

我的组合框1里有数据, 并想知道是否有可能在组合框中按字母顺序对数据进行排序?

我花了很多年试图通过搜索论坛找到答案, 却找不到任何东西,

With ComboBox2
  .DisplayMember = "Name"
  .ValueMember = "FullName"
  .DataSource = New IO.DirectoryInfo("Path").GetFiles() _
  .Select(Function(fi) New With {.Name = _
          IO.Path.GetFileNameWithoutExtension(fi.FullName), fi.FullName}) _
  .ToArray()
End With

Answer 1

先排序数据,然后将数据绑在组合框中。

With ComboBox1
  .DisplayMember = "Name"
  .ValueMember = "FullName"
  .DataSource = New IO.DirectoryInfo("C:asdf").GetFiles() _
  .Select(Function(fi) New With {.Name = _
          IO.Path.GetFileNameWithoutExtension(fi.FullName), fi.FullName}) _
  .OrderBy(Function(fi) CType(fi.Name, Integer)) _
  .ToArray()
End With

Answer 2
