大家好，我是小跳，我来为大家解答以上问题。itemnumber填什么，itemnumber很多人还不知道，现在让我们一起来看看吧！
1、private void frmListView_Load(object sender, EventArgs e) { lvShow.Columns.Clear(); lvShow.View = View.Details; //必不可少。
2、否则无法显示 lvShow.Columns.Add("学号", 120); lvShow.Columns.Add("姓名", 120); lvShow.Columns.Add("性别"); //初始化列表项数据 int itemNumber = lvShow.Items.Count; string[] subItem0 = { "201000101", "Lucy", "女" }; lvShow.Items.Insert(itemNumber, new ListViewItem(subItem0)); string[] subItem1 = { "201000102", "Rose", "女" }; lvShow.Items.Insert(itemNumber, new ListViewItem(subItem1)); string[] subItem2 = { "201000103", "Jack", "男" }; lvShow.Items.Insert(itemNumber, new ListViewItem(subItem2)); } private void btnAdd_Click(object sender, EventArgs e) { int itemNumber = lvShow.Items.Count; string[] subItem = { "201000104", "张三", "男" }; lvShow.Items.Insert(itemNumber, new ListViewItem(subItem)); } private void btnDelete_Click(object sender, EventArgs e) { for (int i = this.lvShow.SelectedItems.Count - 1; i >= 0; i--) { ListViewItem item = lvShow.SelectedItems[i]; lvShow.Items.Remove(item); } }。
本文到此讲解完毕了，希望对大家有帮助。
