您好，

如果您想修剪多个单词，这可以帮助您入门.

希望这会给您一些开始.

用VB更新

Hi there,

This is something to get you started on if you wanted to trim out multiple words.

Hopefully this will give you something to start with.

UPDATED WITH VB

''' <summary>
 ''' Gets the list items.
 ''' </summary>
 ''' <param name="p_textToSearch">The text to search.</param>
 Public Sub GetListItems(ByVal p_textToSearch As String)
     'listBox1 is the listbox you want to populate
     Dim items As New ListBox.ObjectCollection(listBox1)
     If (p_textToSearch.Contains("<")) AndAlso (p_textToSearch.Contains(">")) Then
         Dim wordsStrings As String() = p_textToSearch.Split(">"c)
         For Each wordsString As String In wordsStrings
             Dim firstIndexOfBracket As Integer = wordsString.IndexOf("<", StringComparison.Ordinal)

             If firstIndexOfBracket < 0 Then
                 firstIndexOfBracket = 0
             End If
             Dim preTrim As String = wordsString.Substring(firstIndexOfBracket)
             Dim altered As String = preTrim.Replace("<", "")

             items.Add(altered.Trim())
         Next

     End If
     listBox1.Refresh()
 End Sub

/// <summary>
/// Gets the list items.
/// </summary>
/// <param name="p_textToSearch">The text to search.</param>
public void GetListItems(string p_textToSearch)
{
    //listBox1 is the listbox you want to populate
    ListBox.ObjectCollection items = new ListBox.ObjectCollection(listBox1);
    if ((p_textToSearch.Contains("<")) && (p_textToSearch.Contains(">")))
    {
        string[] wordsStrings = p_textToSearch.Split('>');
        foreach (var wordsString in wordsStrings)
        {
            int firstIndexOfBracket = wordsString.IndexOf("<", StringComparison.Ordinal);

            if (firstIndexOfBracket < 0)
            {
             firstIndexOfBracket = 0;
            }
            string preTrim = wordsString.Substring(firstIndexOfBracket);
            string altered = preTrim.Replace("<", "");

            items.Add(altered.Trim());
        }
    }
    listBox1.Refresh();
}
