使用Winforms和C#在datagridviewCell的单行中显示多个MyObject.Name

public class MultiNameCell : DataGridViewTextBoxCell
{
    protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
    {
        // 绘制单元格背景
        graphics.FillRectangle(new SolidBrush(cellStyle.BackColor), cellBounds);

        // 获取MyObject.Name的值
        List<string> names = (List<string>)value;

        // 设置绘制文本的字体和颜色
        Font font = cellStyle.Font;
        Color textColor = cellStyle.ForeColor;

        // 计算每个名称的绘制位置
        int x = cellBounds.Left + 2;
        int y = cellBounds.Top + (cellBounds.Height - font.Height) / 2;

        // 逐个绘制名称
        foreach (string name in names)
        {
            graphics.DrawString(name, font, new SolidBrush(textColor), x, y);
            x += TextRenderer.MeasureText(name, font).Width + 5; // 间隔为5个像素
        }

        // 绘制单元格边框
        base.Paint(graphics, clipBounds, cellBounds, rowIndex, cellState, value, formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts);
    }
}

// 创建一个DataGridView控件
DataGridView dataGridView = new DataGridView();

// 创建一个列
DataGridViewColumn column = new DataGridViewColumn();
column.CellTemplate = new MultiNameCell(); // 设置单元格模板为自定义的单元格类

// 将列添加到DataGridView中
dataGridView.Columns.Add(column);

// 添加数据行
List<MyObject> objects = GetMyObjects(); // 获取MyObject数据
foreach (MyObject obj in objects)
{
    // 创建一个行
    DataGridViewRow row = new DataGridViewRow();

    // 创建一个单元格
    DataGridViewCell cell = new DataGridViewTextBoxCell();

    // 设置单元格的值为MyObject.Name列表
    List<string> names = obj.Names;
    cell.Value = names;

    // 将单元格添加到行中
    row.Cells.Add(cell);

    // 将行添加到DataGridView中
    dataGridView.Rows.Add(row);
