将字典类型（Dictionary）类型数据序列化为json数据及拼接为key1=value1&key2=value2的两种方法

## 一、序列化为Json字符串 ##

当需要将对象转为`{ "street": "科技园路.", "city": "江苏苏州", "country": "中国"}`这种格式时使用[序列化（不引入外部dll的方式）][dll]

public static String SerializeObject(Object o)
            {
                System.Web.Script.Serialization.JavaScriptSerializer json = new System.Web.Script.Serialization.JavaScriptSerializer();
                String jsonString = json.Serialize(o);
                return jsonString;
            }

在使用上述方法之前先得添加引用“System.Web.Extensions”,然后还得在类前面增加`using System.Web;`

**反序列化为指定对象**

JavaScriptSerializer js = new JavaScriptSerializer();
    Student model = js.Deserialize< Student>(jsonStr);// //反序列化

## 二、将字符串key、value进行&连接 ##

两个方法大同小异  
方法一：

private string dataToString(Dictionary<string,string> data)
            {
                StringBuilder sub = new StringBuilder();
                foreach (string s in data.Keys)
                {
                    if (sub.Length > 0) { 
                        sub.Append("&");
                    }
                    sub.Append(System.Web.HttpUtility.UrlEncode(s) + "=" + System.Web.HttpUtility.UrlEncode(data[s].ToString()));
                }
                return sub.ToString();
          }

方法2：

private string dataToString(Dictionary<string,string> data)
    {
       StringBuilder buffer = new StringBuilder();  
                    int i = 0;
                    foreach (string key in data.Keys)  
                    {  
                        if (i > 0)  
                        {
                            buffer.AppendFormat("&{0}={1}", key, data[key]);  
                        }  
                        else  
                        {
                            buffer.AppendFormat("{0}={1}", key, data[key]);  
                        }  
                        i++;  
                    }
                    return buffer.ToString();
    }

运行结果
