c# 拼接Json串的方法

C#定义多行字符串的方式

在定义的前面加上@符号：

            string aa = @"asdfsdfsd
                        fsdsfsdfsdfsdfsdfsdfs
                        safasfsadfsdfasfsfsdfsd ";

 

在C#中拼接字符串有几种方法

1. 利用  JsonConvert.SerializeObject方法 (Nuget获取Newtonsoft.Json Package)

            string uid = "22";

            var abcObject = new
            {
                AccessKey = 11,
                CustomerNo = uid,
                mc = "33",
                qd = "44",
                mr = "55",
                insertDate = DateTime.Now
            };
            string serJson = JsonConvert.SerializeObject(abcObject);

2. 利用StringBuilder

            StringBuilder str = new StringBuilder();
            str.Append("{");
            str.Append("AccessKey:\"" + 11 + "\",");
            str.Append("mc:\"" + 22 + "\",");
            str.Append("qd:\"" + 33 + "\"");
            str.Append("}");
            string serJson = str.ToString();

3. 直接拼接字符串

        string serJon = "{AccessKey:\"" + 11 + "\",mc:\"" + 22 + "\"}";

4. 利用StringFormat

            string mc = "22";
            string id = "11";
            string serJson = string.Format("[{{ AccessKey:\"{0}\",mc:\"{1}\"}},{{ AccessKey:\"{2}\",mc:\"{3}\"}}]", id, mc, "33", "44");
