C#中ListView的简单使用方法

ListView是用于显示数据的，先在窗体中拉一个lisview控件，还有一些新增、修改、删除、查询按钮和文本框，控件名称为listview,按钮为btnInsert,btnUpate,btnDeleteOne,btnDelete,btnSelect,文本框的名称为txtName,txtSex,txtPhone,txtAddress,设计如下图所示：

写完这些后，先设置listView的一些属性和列标头，如图所示

具体代码如下：

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

    {

            lv.View = View.Details;  //设置显示模式为详细
            lv.HoverSelection = true;  //当鼠标停留数秒后自动选择
            //把列名添加到listview中
            lv.Columns.Add(c1);
            lv.Columns.Add(c2);

            if (lv.SelectedItems.Count > 0) {

　　　　　　//把修改后的文本框内容添加到listview中
                lv.SelectedItems[0].SubItems[0].Text = this.txtName.Text;
                lv.SelectedItems[0].SubItems[1].Text = this.txtSex.Text;

        }

                this.txtName.Text = this.listView.SelectedItems[0].SubItems[0].Text;
                this.txtSex.Text = this.listView.SelectedItems[0].SubItems[1].Text;

            if (this.listView.SelectedItems.Count > 0) {
                //移除整一行
                this.listView.SelectedItems[0].Remove();
            }
        }
       
        /// <summary>

        private void btnDeleteAll_Click(object sender, EventArgs e)
        {    
                //清空整个listview中的行
                this.listView.Items.Clear();
        }

private void btnSelect_Click(object sender, EventArgs e)
        {
            SelectListView(this.listView);
        }

public void SelectListView(ListView lv) {
            //列表有数据
            if (lv.Items.Count > 0)
            {
                foreach (ListViewItem li in lv.Items)
                {
                    if (li.SubItems[0].Text == this.txtExitName.Text)
                    {
                        MessageBox.Show("存在该名称");
                        return;
                    }
                }
                MessageBox.Show("没有找到该姓名");
            }
            else {
                MessageBox.Show("未输入列表数据");
            }
        }
    }
}

最后运行效果是这样的，这是新增数据时的效果

这是修改数据后的效果：

这是查询是否存在这个名字的效果：

删除选中行和删除全部就不显示出来了。
