推荐答案

使用数据表(或更多数据)创建一个DataSet并使用从以下位置加载 [

Create a DataSet with a table (or more) for your data and use the save to[^]/load from[^] XML capabilities.

I guess this would be the easiest way to do it :)

您需要将图像转换为String，因为XML不支持直接二进制数据.

我建议您将其编码为Base64(Convert.ToBase64String()).

You need to convert the image into a String, since XML does not support direct binary data.

I suggest you encode it into Base64 (Convert.ToBase64String()).
