如何在C#中将值从JSON Type对象打印到控制台

Question

我正在尝试使用c#2.0编写一个控制台应用程序,它将使用我的webservice并返回webmethod的结果.

在我的C#代码中,我可以从web方法中获取我的值,请参阅下面的示例代码:

 // print results
            try
            {

                Type objtype = Type.GetType(crisresult.ToString());
                object obj = Activator.CreateInstance(objtype);

                Object[] mArgs = new Object[methodArgs.Length + 1];
                methodArgs.CopyTo(mArgs, 0);
                mArgs.SetValue(obj, methodArgs.Length);
                methodArgs = mArgs;

                Object result = mi.Invoke(service, methodArgs);           
                Console.WriteLine(result);            

            }
            catch (Exception e)
            {
                Console.WriteLine("Error invoking method '" + methodName + "'");
                Console.WriteLine(e);
            }
            Console.WriteLine("Press enter to continue...");
            Console.ReadLine();

现在在上面的代码中,我的webmethod的结果完全以JSON Type返回,所以我Object result有JSON类型的值,例如:

{"FullName":"Mr Mahesh Sharma","Miles":0,"TierStatus":"IO","TierMiles":0,"MilesExpiry":0,"ExpiryDate":"30/03/2012 00:00:00","AccessToken":"106C9FD143AFA6198A9EBDC8B9CC0FB2CE867356222D21D45B16BEEB9A7F390B5E226665851D6DB9","ActiveCardNo":"00300452124","PersonID":8654110}

以上结果,我想在控制台中打印以下格式:

FullName: Mr Mahesh Sharma
Miles: 0
TierStatus: IO
TierMiles:0
MilesExpiry:0
ExpiryDate:31 March 2012
AccessToken: 106C9FD143AFA6198A9EBDC8B9CC0FB2CE867356222D21D45B16BEEB9A7F390B5E226665851D6DB9
ActiveCardNo: 00300452124
PersonID: 8654110

Answer 1

我个人会使用JSON.NET.示例代码:

using System;
using Newtonsoft.Json.Linq;

class Test
{
    static void Main()
    {
        string json = "{\"FullName\":\"Mr Mahesh Sharma\",\"Miles\":0,\"TierStatus\":\"IO\"," +
            "\"TierMiles\":0,\"MilesExpiry\":0,\"ExpiryDate\":\"30/03/2012 00:00:00\"," + 
            "\"AccessToken\":\"106C9FD143AFA6198A9EBDC8B9CC0FB2CE867356222D21D45B16BEE" + 
            "B9A7F390B5E226665851D6DB9\",\"ActiveCardNo\":\"00300452124\",\"PersonID\":8654110}";

        JObject parsed = JObject.Parse(json);

        foreach (var pair in parsed)
        {
            Console.WriteLine("{0}: {1}", pair.Key, pair.Value);
        }
    }
}

输出:

FullName: "Mr Mahesh Sharma"
Miles: 0
TierStatus: "IO"
TierMiles: 0
MilesExpiry: 0
ExpiryDate: "30/03/2012 00:00:00"
AccessToken: "106C9FD143AFA6198A9EBDC8B9CC0FB2CE867356222D21D45B16BEEB9A7F390B5E226665851D6DB9"
ActiveCardNo: "00300452124"
PersonID: 8654110

请注意,每对中的值都是a JToken,您可以将其强制转换为相关类型.

Answer 2

您可以使用以下内容:

return Newtonsoft.Json.JsonConvert.SerializeObject( obj, Formatting.Indented );

简单干净.
