.net 图片Base64编码

解析图片Base64编码：

            System.IO.MemoryStream ms = new System.IO.MemoryStream();            System.Drawing.Bitmap bp = new System.Drawing.Bitmap(@"d:\image\splash1.png");            bp.Save(ms,System.Drawing.Imaging.ImageFormat.Png);             txtBaseCode.Text = Convert.ToBase64String(ms.GetBuffer());

根据Base64编码获取图片：

 byte[] bt = Convert.FromBase64String(txtBaseCode.Text.Trim());            System.IO.MemoryStream stream = new System.IO.MemoryStream(bt);            System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(stream);            bitmap.Save(@"d:\image\splash2.png");
