我正在尝试在下面的问题结尾处反序列化示例JSON。但results.count始终为0。 如何使用多个数据反序列化此JSON,以便我可以使用
循环foreach (Foo r in results)
{
Response.Write(r.html);
}
[Serializable()]
public class Foo
{
public string html { get; set; }
public string bannerid { get; set; }
public string contenttype { get; set; }
public string alt { get; set; }
public string width { get; set; }
public string height { get; set; }
public string url { get; set; }
public string bannertext { get; set; }
public string bannerurl { get; set; }
public string campaignid { get; set; }
public string version { get; set; }
public string cpc { get; set; }
}
public List<Foo> GetFooMultiple(string publisherOrSiteId)
{
JavaScriptSerializer ser = new JavaScriptSerializer();
List<Foo> results = ser.Deserialize<List<Foo>>(json);
return results;
}
List<Foo> results = GetFooMultiple("11111,22222");
Response.Write(results.Count);
Json string:
"{ "11111" : { "alt" : "none",
"bannerid" : "21655",
"bannertext" : "Sample 1",
"bannerurl" : "http://foo.com/foo.png",
"campaignid" : "1216",
"contenttype" : "png",
"cpc" : "0.00060",
"height" : 50,
"html" : "<a href='http://foo.com/foo.png'><img src='http://foo.com/foo.png' width='320' height='50' alt='foo' /></a>",
"url" : "http://foo.com/foo.png",
"version" : "1",
"width" : 320
},
"22222" : { "alt" : "",
"bannerid" : "21937",
"bannertext" : "Sample 2",
"bannerurl" : "",
"campaignid" : "1241",
"contenttype" : "txt",
"cpc" : "0.00060",
"height" : 0,
"html" : "<a href='http://foo.com/foo.pngD'>Sample 2</a>",
"url" : "http://foo.com/foo.png",
"version" : "1",
"width" : 0
}
}"
JSON作为C#字符串,用于MVCE:
string json = @"{ ""11111"" : {
""alt"" : ""none"",
""bannerid"" : ""21655"",
""bannertext"" : ""Sample 1"",
""bannerurl"" : ""http://foo.com/foo.png"",
""campaignid"" : ""1216"",
""contenttype"" : ""png"",
""cpc"" : ""0.00060"",
""height"" : 50,
""html"" : ""<a href='http://foo.com/foo.png'><img src='http://foo.com/foo.png' width='320' height='50' alt='foo' /></a>"",
""url"" : ""http://foo.com/foo.png"",
""version"" : ""1"",
""width"" : 320
},
""22222"" : {
""alt"" : """",
""bannerid"" : ""21937"",
""bannertext"" : ""Sample 2"",
""bannerurl"" : """",
""campaignid"" : ""1241"",
""contenttype"" : ""txt"",
""cpc"" : ""0.00060"",
""height"" : 0,
""html"" : ""<a href='http://foo.com/foo.pngD'>Sample 2</a>"",
""url"" : ""http://foo.com/foo.png"",
""version"" : ""1"",
""width"" : 0
}
}";

JSON.NET支持这种类型的结构。所以你可以这样做:
var result = JsonConvert.DeserializeObject<IDictionary<string, Foo>>(json);
然后:
var foo1 = result["11111"];
var foo2 = result["22222"];

什么是publisherOrSiteId
参数和什么是“11111”和“22222”在你的json字符串中做什么?正确的JSON将是
"[{ "alt" : "none",
"bannerid" : "21655",
"bannertext" : "Sample 1",
"bannerurl" : "http://foo.com/foo.png",
"campaignid" : "1216",
"contenttype" : "png",
"cpc" : "0.00060",
"height" : 50,
"html" : "<a href='"http://foo.com/foo.png'><img src='"http://foo.com/foo.png' width='320' height='50' alt='foo' /></a>",
"url" : ""http://foo.com/foo.png",
"version" : "1",
"width" : 320
},
{ "alt" : "",
"bannerid" : "21937",
"bannertext" : "Sample 2",
"bannerurl" : "",
"campaignid" : "1241",
"contenttype" : "txt",
"cpc" : "0.00060",
"height" : 0,
"html" : "<a href='http://foo.com/foo.pngD'>Sample 2</a>",
"url" : "http://foo.com/foo.png",
"version" : "1",
"width" : 0
}]"

我不同意见。 JavaScriptSerializer
可以反序列化Dictionary<string, Foo>
:
var results = ser.Deserialize<Dictionary<string, Foo>>(json); // json now defined in question
var foo1 = results["11111"];
Console.WriteLine(results["11111"].bannerid); // 21655 expected
输出
21655
