我有以下有效的JSON,我需要遍历结果。我正在使用JSON.NET和c#。我能够获得SUCCESS的价值,但我不知道如何访问任何指导都会有所帮助。
{
"SUCCESS": 1,
"ERRMSG": "",
"COLUMNSANDDATA": {
"COLUMNS": ["LASTNAME", "FIRSTNAME", "EMAILADDRESS", "COURSENAME", "PROGRAMID",
"ENROLLMENTSTARTDATE", "COMPLETIONDATE", "GRADE", "SCORE",

]
}
}
我可以使用这段代码获取SUCCESS值
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
var deserializer = new JavaScriptSerializer();
var jsonObj = (IDictionary<string, object>)deserializer.DeserializeObject(result); ;
Response.Write((string)jsonObj["SUCCESS"]);
}

这样的事情应该有用,对不起它没有经过测试。
float **b = new float*[n]; //create local matrix
b[0] = new float[n*nCols] {0.0f}; // this line changed
for (int j = 1; j < n; j++) b[j] = b[j-1] + n;

WHERE A.B_ID IN

我强烈建议您使用自动生成的类来最舒适地导航和使用theese类。
看看这篇文章How to auto-generate a C# class file from a JSON object string它将帮助你完成自动生成classe形式的json和xml。顺便说一下,它将来会帮助你。
var deserializer = new JavaScriptSerializer();
var jsonObj = deserializer.DeserializeObject<RootObject>(result);

您可以遍历JSON并将所有内容转储出来:
string json = @"
{
""SUCCESS"": 1,
""ERRMSG"": """",
""COLUMNSANDDATA"": {
""COLUMNS"": [""LASTNAME"", ""FIRSTNAME"", ""EMAILADDRESS"", ""COURSENAME"", ""PROGRAMID"", ""ENROLLMENTSTARTDATE"", ""COMPLETIONDATE"", ""GRADE"", ""SCORE"", ""PASSED_NOTPASSED"", ""TYPEOFCREDITS"", ""CREDITSEARNED"", ""INSTRUCTORNAME"", ""INSTRUCTOREMAILADDRESS"", ""CLIENTNAME"", ""COMMUNITYNAME"", ""CERTIFICATESENTDATE"", ""DURATIONTYPE"", ""DURATIONMINUTES"", ""LOGIN""],
""DATA"": [
[""Beane"", ""Coffee"", ""lynn@domain.com"", ""Program with One Essay Test"", null, ""January, 06 2014 18:06:56"", ""January, 06 2014 18:57:53"", ""Incomplete"", null, ""Not Passed"", ""Musical Note"", 0.00, ""Ray Bradbury"", ""lynn@domain.com"", ""Hogarth's Flying Circus"", ""Captain's Club"", null, null, null, ""lynn@domain.com""],
[""Beane"", ""Navy"", ""lynn@domain.com"", ""Program with One Essay Test"", null, ""January, 06 2014 18:06:56"", ""January, 06 2014 18:36:39"", ""Pass"", 95.00, ""Passed"", ""Musical Note"", 1.00, ""Ray Bradbury"", ""lynn@domain.com"", ""Hogarth's Flying Circus"", ""Captain's Club"", ""January, 06 2014 08:00:00"", null, null, ""NavyB""]
]
}
}";
JObject root = JObject.Parse(json);
JObject colsAndData = (JObject)root["COLUMNSANDDATA"];
JArray cols = (JArray)colsAndData["COLUMNS"];
foreach (JArray row in colsAndData["DATA"])
{
for (int i = 0; i < row.Count; i++)
{
string colName = (string)cols[i];
string value = (string)row[i];
Console.WriteLine(colName + ": " + value);
}
Console.WriteLine();
}
