c# listview怎样简化代码

在C#中，为了简化ListView的代码，您可以使用以下方法：

1. 使用LINQ查询来填充ListView的数据。这样可以减少循环和条件语句的数量，使代码更加简洁。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;

public class ListViewExample : Form
{
    private ListView listView;
    private List people;

    public ListViewExample()
    {
        listView = new ListView();
        listView.Dock = DockStyle.Fill;
        listView.Columns.Add("Name", 100);
        listView.Columns.Add("Age", 50);

        people = new List
        {
            new Person { Name = "Alice", Age = 30 },
            new Person { Name = "Bob", Age = 25 },
            new Person { Name = "Charlie", Age = 35 }
        };

        listView.Items.AddRange(people.Select(p => new ListViewItem(new[] { p.Name, p.Age.ToString() })).ToArray());

        this.Controls.Add(listView);
    }

    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new ListViewExample());
    }
}

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

2. 使用数据绑定来填充ListView的数据。这样可以进一步减少代码量，使代码更加简洁。

using System;
using System.Collections.ObjectModel;
using System.Windows.Forms;

public class ListViewExample : Form
{
    private ListView listView;
    private ObservableCollection people;

    public ListViewExample()
    {
        listView = new ListView();
        listView.Dock = DockStyle.Fill;
        listView.Columns.Add("Name", 100);
        listView.Columns.Add("Age", 50);

        people = new ObservableCollection
        {
            new Person { Name = "Alice", Age = 30 },
            new Person { Name = "Bob", Age = 25 },
            new Person { Name = "Charlie", Age = 35 }
        };

        listView.ItemsSource = people;

        this.Controls.Add(listView);
    }

    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new ListViewExample());
    }
}

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

这两种方法都可以简化ListView的代码，使代码更加简洁和易于维护。
