二代身份证阅读器（XZX）
2024-04-19 08:26:29
问题一
解决方法：
通常我把所有的dll复制到system32文件夹，64位系统复制到sysWOW64文件夹，而且编译选项CPU要选择X86
问题二
解决方法：
图片路径默认是C:\，对C:\没有写的权限，所以提示此错误。改变此路径到别的盘符就可以解决。
以下是我编写的代码
1 public class IDCardHelper
2 {
3 #region 数据类型和导入接口

本人用ASP.NET开发的，图片会保存到本地，需要上传到服务器端才能在网页中查看，以下是上传图片的方法
1 public bool UploadPhoto(string photoPath)
2 {
3 FileStream stream = new FileStream(photoPath, FileMode.Open, FileAccess.Read);
4 int size = Convert.ToInt32(stream.Length);
5 Byte[] MeaningFile = new Byte[size];
6 stream.Read(MeaningFile, 0, size);
7 stream.Close();
8 FileStream photoStream = null;
9
10 string fileName = photoPath.Substring(photoPath.LastIndexOf("\\") + 1);
11 string fileExt = photoPath.Substring(photoPath.LastIndexOf(".") + 1);
12 if (fileExt.ToLower() == "bmp")//必须是bmp文件
