我想将以下字符串存储在String变量
中{ “ID”: “123”, “DateOfRegistration”: “2012-10-21T00:00:00 + 05:30”, “状态”:0}
这是我使用的代码..
String str="{"Id":"123","DateOfRegistration":"2012-10-21T00:00:00+05:30","Status":0}";
..但它显示错误..

你必须这样做
String str="{\"Id\":\"123\",\"DateOfRegistration\":\"2012-10-21T00:00:00+05:30\",\"Status\":0}";
请see this for reference
另外from msdn :)

我更喜欢这个,只要确保你在字符串
中没有单引号string str = "{'Id':'123','DateOfRegistration':'2012 - 10 - 21T00: 00:00 + 05:30','Status':0}".Replace("'", "\"");

有另一种方法可以使用Expando对象或XElement编写这些复杂的JSON,然后进行序列化。
dynamic contact = new ExpandoObject();
contact.Name = “Patrick Hines”;
contact.Phone = “206-555-0144”;
contact.Address = new ExpandoObject();
contact.Address.Street = “123 Main St”;
contact.Address.City = “Mercer Island”;
contact.Address.State = “WA”;
contact.Address.Postal = “68402”;
//Serialize to get Json string using NewtonSoft.JSON
string Json = JsonConvert.SerializeObject(contact);

您必须转义字符串中的引号,如下所示:
String str="{\"Id\":\"123\",\"DateOfRegistration\":\"2012-10-21T00:00:00+05:30\",\"Status\":0}";

你需要像这样逃避内部引号:
String str="{\"Id\":\"123\",\"DateOfRegistration\":\"2012-10-21T00:00:00+05:30\",\"Status\":0}";

在@ sudhAnsu63上进行微调,这是一个单线:
使用 NET Core
string str = JsonSerializer.Serialize(
new {
Id = 2,
DateOfRegistration = "2012-10-21T00:00:00+05:30",
Status = 0
}
);
使用 Json.Net
string str = JsonConvert.SerializeObject(
new {
Id = 2,
DateOfRegistration = "2012-10-21T00:00:00+05:30",
Status = 0
}
);
不需要实例化dynamic ExpandoObject
。

对于开箱即用的解决方案,我将 JSON 编码为 base64,以便它可以在一行中作为字符串值导入。
这会保留行格式,而无需您手动编写动态对象或转义字符。格式与从文本文件中读取 JSON 的格式相同:
var base64 = "eyJJZCI6IjEyMyIsIkRhdGVPZlJlZ2lzdHJhdGlvbiI6IjIwMTItMTAtMjFUMDA6MDA6MDArMDU6MzAiLCJTdGF0dXMiOjB9";
byte[] data = Convert.FromBase64String(base64);
string json = Encoding.UTF8.GetString(data);
//using the JSON text
var result = JsonConvert.DeserializeObject<object>(json);

使用逐字字符串文字 (@"..."
),您可以通过将双引号与双引号对交换来编写内联多行 json - "" 而不是 "。示例:
string str = @"
{
""Id"": ""123"",
""DateOfRegistration"": ""2012-10-21T00:00:00+05:30"",
""Status"": 0
}";
