列表框中的选定项到数组 [英] Selected Items in a ListBox to an Array

问题描述

大家好，

我是VB.Net的NUBIE，但学习很快.我有一个listbox2设置为Selectionmode = Extended，需要将列表框中的选定项捕获到数组中，以便以后进行操作.我可以轻松地获得第一个选定的项目文本，但是当我遍历代码时，它会继续重复第一个文本来填充数组.

任何帮助或建议，将不胜感激.

Hi All,

Im a NUBIE to VB.Net but am learning quickly. I have a listbox2 that is set to Selectionmode = Extended and need to capture the selected items in the list box to an array for a later action. I can easily get the first selected items text but as I iterate through the code it continues to populate the array with a repeat of the first text.

Any help or advice would be greatly appreciated.

Dim RDFs = ListBox2.SelectedItems.Count

Dim RDFsArry(RDFs) As String
Dim index2 As Integer
index2 = 0
For Each selectedItems In ListBox2.SelectedIndex.ToString
    RDFsArry(index2) = (ListBox2.SelectedItem).ToString
    index2 = index2 + 1

Next

推荐答案

您使用的For Each 错误.它循环遍历一个集合，而ListBox2.SelectedIndex不是一个集合.尝试使用ListBox2.SelectedIndices.

You are using the For Each incorrectly. It loops through a collection and ListBox2.SelectedIndex is not a collection. Try using ListBox2.SelectedIndices.

，假设项目在下面的代码中是字符串，但是您需要遍历列表框的选定索引

assuming that the items are string in the code below, but you need to go through the selectedindices of the listbox

For Each item As String In ListBox2.SelectedIndices
  RDFsArray(index2) = item
  index2 = index2 + 1
Next

不起作用，现在出现以下错误...

SelectedIndices''不是System.Windows.Controls.ListBox的成员

Did not work, getting the following error now...

SelectedIndices'' is not a member of System.Windows.Controls.ListBox
