根据值更改WPF DataGrid列上的图像

public class ValueToImageConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        // 根据数据值返回对应的图像路径或图像对象
        if (value != null)
        {
            // 根据具体的值进行判断，并返回对应的图像路径或图像对象
            if (value.ToString() == "Value1")
            {
                return "Images/image1.png"; // 图像路径
            }
            else if (value.ToString() == "Value2")
            {
                return new BitmapImage(new Uri("Images/image2.png", UriKind.Relative)); // 图像对象
            }
        }

        return null; // 如果值无效或未定义图像，则返回null
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
