非托管类，身份证接口调用

1.装人口信息系统接口软件

2.程序-人口信息系统接口软件- 右键delphitest 属性 -寻找目标 -开发包-termb.dll、WltRS.dll 考到开发文件debug里

3代码如下：

using System.Runtime.InteropServices;
using System.Text;

 [DllImport("termb.dll", EntryPoint = "InitComm")]
        static extern int InitComm(int Port);
        [DllImport("termb.dll", EntryPoint = "CloseComm")]
        static extern int CloseComm();
        [DllImport("termb.dll", EntryPoint = "Read_Content")]
        static extern int Read_Content(int Active);
        [DllImport("termb.dll", EntryPoint = "GetPeopleName")]
        static extern int GetPeopleName(StringBuilder strbl, int strLen);
        [DllImport("termb.dll", EntryPoint = "Authenticate")]
        static extern int Authenticate();

  private void button1_Click(object sender, EventArgs e)
        {
            int li_ret = 0;
            int li_port = 1001;

            li_ret = InitComm(li_port);
            int at = Authenticate();
            Read_Content(1);
            StringBuilder strbl = new StringBuilder();
            int strLen = 30;
            GetPeopleName(strbl, strLen);

            int cl = CloseComm();
        }
