推荐答案

你不能在ListBox中轻松完成。使用Graphics绘制它们并不容易。我建议使用 DataGridView o ListView 控件。

You can't do that easily in the ListBox. And drawing them using Graphics is not easy at all. I suggest using a DataGridView o ListView control instead.

结果：

DataGridView ：有一个名为的DataType DataGridViewImageColumn 您可以用来显示您的状态图标。

DataGridView: There's a ColumnType called DataGridViewImageColumn that you can use to show your status icon.

public void FillDataGridView()
{
    //images
    var greenImg = Resources.green;
    var redImg = Resources.red;
    var yellowImg = Resources.yellow;

    dataGridView1.Rows.Add(new object[] {"Vland", greenImg});
    dataGridView1.Rows.Add(new object[] {"John", yellowImg });
    dataGridView1.Rows.Add(new object[] {"Paul", greenImg});
    dataGridView1.Rows.Add(new object[] {"George", redImg});
    dataGridView1.Rows.Add(new object[] {"Ringo", redImg });
}

如何：在Windows窗体DataGridView控件的单元格中显示图像

ListView：可以添加由文字+图片组成的项目。如果你使用ListView，你需要在你的表单中添加一个imageList组件（包含你的图像）并调用他们的 imageKey 值，如示例中所示

ListView: can add items composed by text + image. If you use the ListView, you need to add an imageList component to your form (with your images in it) and call their imageKey value like shown in the example

public void fillListView()
{
    listView1.SmallImageList = imageList1;

    listView1.Items.Add("BombPenguin", "green");
    listView1.Items.Add("Vland", "yellow");
    listView1.Items.Add("John", "red");
    listView1.Items.Add("Paul", "green");
    listView1.Items.Add("Ringo", "red");
}
