試圖搜索ListView以匹配字符串的子項目

Question

我無法通過ListView掃描來查找與給定字符串匹配的子項目。這裏是我的代碼：

private void dateTimePicker1_ValueChanged(object sender, EventArgs e) 
    { 
     string date = datePicker.Value.ToShortDateString(); 
     int count = Program.booker.listView.Items.Count; 

     for (int i = 0; i < count; i++) 
     { 
      ListViewItem lvi = Program.booker.listView.Items[i]; 

      if (lvi.SubItems.Equals(date)) 
      { 
       MessageBox.Show("Found!", "Alert"); 
       Program.booker.listView.MultiSelect = true; 
       Program.booker.listView.Items[i].Selected = true; 
      } 
      else 
      { 
       MessageBox.Show("Nothing found for " + date, "Alert"); 
      } 
     } 
    } 

ListView控件位於布克形式，而我從過濾器類訪問它。我想搜索整個ListView的任何匹配我的日期字符串的項目。謝謝！

您可以使用FindItemWithText方法。

ListViewItem searchItem = null; 
int index = 0; 
do 
{ 
    if (index < Program.booker.listView.Items.Count) 
    { 
     //true = search subitems 
     //last false param = no partial matches (remove if you want partial matches) 
     searchItem = Program.booker.listView.FindItemWithText(date, true, index, false); 
     if (searchItem != null) 
     { 
      index = searchItem.Index + 1; 

      //rest of code 
     } 
    } 
    else 
     searchItem =null; 

} while (searchItem != null);
