c#将一个对象转换成json
class AllyRequestIO
{
/*//请求随机数
private String random { get; set; }
//请求参数
private String iparams { get; set; }*/

    public String token { get; set; }
    public int payType { get; set; }
    public Decimal amount { get; set; }
    public String use { get; set; }
    public String remark { get; set; }
    public String orgId { get; set; }
    public long merchantId { get; set; }
    public String pbucode { get; set; }
    public String accno { get; set; }
    public String accname { get; set; }
    public String bankcode { get; set; }
    public String ubankno { get; set; }
    public String cusno { get; set; }
    public int acctype { get; set; }
}

                AllyRequestIO aio = new AllyRequestIO();
        aio.token = "e993ffb0-54a7-4446-8b17-937f1454d214";
        aio.payType = 1;
        aio.amount = (Decimal)111.00;
        aio.use = "余额充值";
        aio.remark = "用户：超级管理员充值余额";
        aio.orgId="DDA607C7-C875-4B3A-AA29-4D435F2A4295";
        aio.merchantId = 1;
        aio.pbucode = "TEST";
        aio.accno = "6225842255849524451";
        aio.accname = "李四";
        aio.bankcode = "CCB";
        aio.ubankno = "衣冠庙支行";
        aio.cusno = "3625";
        aio.acctype = 2;


                    我要将aio转换成json，怎么做？

Answer 1

利用DataContractJsonSerializer类， 加这个引用System.Runtime.Serialization.Json; string jsonString = Jsonlper.JsonSerializer(aio);序列化之后就是json字符串了
