我如何在WPF中读取base64图像？

using System.Windows.Media.Imaging;
using System.IO;

public void LoadImageFromBase64(string base64String)
{
    // 将Base64字符串转换为字节数组
    byte[] imageBytes = Convert.FromBase64String(base64String);

    // 使用BitmapImage类将字节数组转换为图像
    BitmapImage image = new BitmapImage();
    using (var mem = new MemoryStream(imageBytes))
    {
        mem.Position = 0;
        image.BeginInit();
        image.CreateOptions = BitmapCreateOptions.PreservePixelFormat;
        image.CacheOption = BitmapCacheOption.OnLoad;
        image.UriSource = null;
        image.StreamSource = mem;
        image.EndInit();
    }

    // 将转换后的图像设置为图像控件的源
    ImageControl.Source = image;
}
