以下在我的Windows 7开发机器上工作正常，但是当在Windows XP上运行时，我得到并在最后一行说明“参数无效”的异常？

byte[] bytes = Convert.FromBase64String(base64String);
System.IO.MemoryStream ms = new System.IO.MemoryStream(bytes);
System.Drawing.Image b = System.Drawing.Image.FromStream(ms, false, false);

这个base64字符串字符串在两个操作系统上都能正常工作。它也是一个图标，但尺寸较小：

答案 0 :(得分：3)

XP真的让人感觉很长。它缺少的一件事是gdiplus.dll的1.10版，这是对Vista首次发布的GDI +的更新。该版本中有很多修复，现在它实际上支持ImageFormat.Icon。

您的图片数据代表.ico文件。请改用Icon（Stream）构造函数。您可能仍然有24bpp图标的问题，我无法再检查它。

答案 1 :(得分：0)

using (MemoryStream ms = new MemoryStream())
    {
        image.Save(ms,System.Drawing.Imaging.ImageFormat.Jpeg);
        ms.Seek(0,0);
        byte[] data = new byte[0];
        data = ms.ToArray();          
    }

我想访问support.how以外的数据
