Question

C# 生成 json 格式

"programmers": [
{ "firstName": "Brett", "lastName":"McLaughlin", "email": "aaaa" },
{ "firstName": "Jason", "lastName":"Hunter", "email": "bbbb" },
{ "firstName": "Elliotte", "lastName":"Harold", "email": "cccc" }
],
"authors": [
{ "firstName": "Isaac", "lastName": "Asimov", "genre": "science fiction" },
{ "firstName": "Tad", "lastName": "Williams", "genre": "fantasy" },
{ "firstName": "Frank", "lastName": "Peretti", "genre": "christian fiction" }
],
"musicians": [
{ "firstName": "Eric", "lastName": "Clapton", "instrument": "guitar" },
{ "firstName": "Sergei", "lastName": "Rachmaninoff", "instrument": "piano" }
] }
我想生成这种格式的json 使用C#如何写

Answer 1

分成两部分：
1 类型定义部分，这部分可以手工定义，也可以采用工具定义，我个人使用vs2012的一个插件，可以选择性粘贴json为class，这个插件目前是测试版所以就不推荐了，你可以选择其他类似工具
public class Rootobject
{
public Programmer[] programmers { get; set; }
public Author[] authors { get; set; }
public Musician[] musicians { get; set; }
}
public class Programmer
{
public string firstName { get; set; }
public string lastName { get; set; }
public string email { get; set; }
}
public class Author
{
public string firstName { get; set; }
public string lastName { get; set; }
public string genre { get; set; }
}
public class Musician
{
public string firstName { get; set; }
public string lastName { get; set; }
public string instrument { get; set; }
}

第二部分，数据填充和转换工作，我这里演示过程，所以数据我随便填，你自己看着改

Rootobject b = new Rootobject()
{
programmers = new Programmer[]{
new Programmer(){ firstName="Brett", lastName="McLaughlin", email="aaaa"},
new Programmer(){ firstName="Jason", lastName="Hunter", email="bbbb"}
},
authors = new Author[]{
new Author(){ firstName="fa",lastName="la", genre="ga"},
new Author(){ firstName="fa1",lastName="la1",genre="ga1"}

},
musicians = new Musician[]{

new Musician(){ firstName="mm",lastName="lm",instrument="im"},
new Musician(){firstName="mm1",lastName="lm1",instrument="im1"}
}
};
JavaScriptSerializer oSerializer =
new System.Web.Script.Serialization.JavaScriptSerializer();
var json = oSerializer.Serialize(b);

//最后这json就是你要转换后的json字符串

Answer 2

如果你想简单些的话，网上有现成；如果你不想发布时附随dll的话就要自己写的了...

Answer 3

利用 Newtonsoft.Json.dll 自己去百度一下，简单到我不想解释
