我有一个.NET字典,其中包含来自Entity Framework中的SQL函数的项目.这是我将代码添加到字典的代码:
public FooViewModel GetFoo()
{
var fooresults = new FooResultsViewModel();
using (var db = new DBEntities())
{
var results = db.FunctionResults().ToList();
foreach (var d in results)
{
foo.a.Add(d.ColumnName, d.ColumnValue);
}
}
return fooresults;
这是我的模型:
public class FooViewModel : GraphViewModel
{
public FooResultsViewModel() { }
public Dictionary<string, decimal> a = new Dictionary<string, decimal>();
}
最后这是我的控制器:
public virtual JsonResult GetData()
{
var fooresults = new FactSurveryResultsQueries().GetAverages();
return new JsonResult { JsonRequestBehavior = JsonRequestBehavior.AllowGet, Data = fooresults };
}
这是返回的JSON:
{"a":
{"FooResult1":3.579831,
"FooResult2":3.359243,
"FooResult3":3.720588,
"FooResult4":3.636554,
"FooResult5":3.285714,
"FooResult6":3.758403,
"FooResult7":3.262605}}
但是,我正在寻找一些返回的东西:
{"a":
{ColumnName:"FooResult1",
ColumnValue:3.579831,
ColumnName:"FooResult2",
ColumnValue:3.359243,
ColumnName:"FooResult3",
ColumnValue:3.720588,
ColumnName:"FooResult4",
ColumnValue:3.636554,
ColumnName:"FooResult5",
ColumnValue:3.285714,
ColumnName:"FooResult6",
ColumnValue:3.758403,
ColumnName:"FooResult7",
ColumnValue:3.262605}}
有没有办法格式化第二个结果的JSON输出?
最佳答案 我想你已经忘了添加{&在每对ColumName,ColumnValue之间,并将其作为一个数组进行序列化.
相反,您的JSON无效或不是JSON,因为您多次重复相同的属性名称.
如果我是对的,这是一个以你想要的方式塑造一个字典的测试用例:
[TestClass]
public class CustomDictionaryJsonSerialization
{
[TestMethod]
public void SerializeDictionary()
{
Dictionary<string, object> dict
= new Dictionary<string, object> {{"col1", 1}, {"col2", "two"}};
var nameValues = dict.Keys.Select(k =>
new {ColumnName = k, ColumnValue = dict[k]});
var toSerialize = new {a = nameValues.ToList()};
string serialized = JsonConvert.SerializeObject(toSerialize);
Assert.IsNotNull(serialized);
}
}
获得的序列化值如下:
{"a":
[ { "ColumnName":"col1", "ColumnValue":1 },
{ "ColumnName":"col2", "ColumnValue":"two" } ]
}
