1、序列化

/// <summary>
    /// 序列化为xml，返回规范化数据
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="c"></param>
    /// <returns></returns>
    public static string ToXml<T>(T c) where T : class
    {
        string str = string.Empty;
        XmlWriterSettings settings = new XmlWriterSettings();
        settings.Encoding = Encoding.GetEncoding("GB2312");
        settings.OmitXmlDeclaration = true;//是否编写声明
        settings.NewLineOnAttributes = true;
        //settings.Indent = true;
        XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
        namespaces.Add("","");
        using (MemoryStream ms = new MemoryStream())
        {
            using (XmlWriter writer = XmlWriter.Create(ms,settings))
            {
                //writer.WriteRaw("<?xml version='1.0' encoding='GB2312' standalone='yes'?>\r\n");
                writer.WriteRaw("<?xml version='1.0' encoding='GB2312' standalone='yes'?>");
                XmlSerializer serializer = new XmlSerializer(c.GetType());
                serializer.Serialize(writer,c,namespaces);
                byte[] arr = ms.ToArray();
                str = Encoding.GetEncoding("GB2312").GetString(arr,arr.Length);
                return str;
            }
        }
    }

2、加密

@H_403_7@public class Md5Util { /// <summary> /// 密钥 /// </summary> public static readonly string key = "134143141"; /// <summary> /// HMAC_MD5 算法 /// </summary> /// <param name="key">密钥</param> /// <param name="str">明文</param> /// <returns></returns> public static string GetHMAC_Md5String(string key,string str) { byte[] keybytes = GetUTF8(key); using (HMACMD5 hmac = new HMACMD5(keybytes)) { byte[] bs = hmac.ComputeHash(GetUTF8(str)); StringBuilder sb = new StringBuilder(); foreach (byte b in bs) { sb.AppendFormat("{0:x2}",b); } return sb.ToString(); } } /// <summary> /// 返回字节数组 /// </summary> /// <param name="content"></param> /// <returns></returns> public static byte[] GetUTF8(string content) { byte[] bytes = Encoding.UTF8.GetBytes(content); return bytes; } /// <summary> /// 返回指定数组的md5哈希值 /// </summary> /// <param name="sources"></param> /// <returns></returns> public static byte[] GetHash(byte[] sources) { MD5CryptoServiceProvider MD5CSP = new MD5CryptoServiceProvider(); byte[] targets = MD5CSP.ComputeHash(sources); return targets; } }
