Csharp C# 扩展一个 listView 包含具有自定义对象的列

要能够使用类似的内容将Project直接添加到ListView:

Project project = new Project
{
    ProjectName = "Big Project",
    Revenue = 12000000
};
listViewProject.Items.Add(project); 

你可以用implicit cast.那就行了.

internal class Project
{
    // Automatic, transparent conversion to ListViewItem
    public static implicit operator ListViewItem(Project project)
    {
        return new ListViewItem(new []
        {  
              project.UUID, 
              project.ProjectName, 
              project.Revenue.ToString()
        });
    }
    public string UUID { get; set; } = Guid.NewGuid().ToString();
    public string ProjectName { get; set; }
    public int Revenue { get; set; }
}

TEST

public partial class MainForm : Form
{
    public MainForm()
    {
        InitializeComponent();
    }
    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        listViewProject.Columns.Add(nameof(Project.UUID), 400);
        listViewProject.Columns.Add(nameof(Project.ProjectName), 150);
        listViewProject.Columns.Add(nameof(Project.Revenue), 100);
    }
    private void buttonAddProjectItem_Click(object sender, EventArgs e)
    {
        Project project = new Project
        {
            ProjectName = $"Project {_tstCount++}",
            Revenue = Rando.Next(1000, 10000)
        };
        listViewProject.Items.Add(project);
    }

    char _tstCount = 'A';
    Random Rando = new Random();
}
