推荐答案

一种方法是导航到 http://json2csharp.com/ ，粘贴您的Json并点击"GO".

One way is to navigate to http://json2csharp.com/, paste your Json and hit "GO".

结果将是这个(我固定为大写):

The result will be this one (I fixed the capitalization):

public class Result {
    public string Company { get; set; }
    public string City { get; set; }
    public string State { get; set; }
}

public class RootObject {
    public int Version { get; set; }
    public string Query { get; set; }
    public int Begin { get; set; }
    public int End { get; set; }
    public int TotalResults { get; set; }
    public int PageNumber { get; set; }
    public Result[] Results { get; set; }
}

将此粘贴​​到您的应用程序中.

Paste this into your application.

您的POST方法可能如下所示:

Your POST-Method then could look like this:

[WebInvoke(Method = "POST", UriTemplate = "")]
public HttpResponseMessage Add(RootObject root) {

    // do something with your root objects or its child objects...

    return new HttpResponseMessage(HttpStatusCode.Created);
}

您已完成此方法.

另一种方法是使用Web API引入的新JsonValue和JsonArray，而您不需要RootObject和Result.

Another method is to use the new JsonValue and JsonArray introduced with Web API whereas you don't need RootObject and Result.

只需使用您的POST方法:

Just use your POST-Method:

[WebInvoke(Method = "POST", UriTemplate = "")]
public HttpResponseMessage Add(JsonValue json) {
    JsonArray arr = (JsonArray) json["results"];
    JsonValue result1 = arr[0];
    var company = result1["company"]; // results in "ABC Company Inc."
    return new HttpResponseMessage(HttpStatusCode.Created);
}

您应该得到一个线索...

You should get a clue...

您可以美化整件事:

[WebInvoke(Method = "POST", UriTemplate = "")]
public HttpResponseMessage Add(JsonValue json) {
    var arr = json["results"];
    var result1 = arr[0];
    var company = result1["company"]; // results in "ABC Company Inc."
    return new HttpResponseMessage(HttpStatusCode.Created);
}
