使用Json非常简单。NET:

dynamic stuff = JsonConvert.DeserializeObject("{ 'Name': 'Jon Smith', 'Address': { 'City': 'New York', 'State': 'NY' }, 'Age': 42 }");

string name = stuff.Name;
string address = stuff.Address.City;

同样使用Newtonsoft.Json.Linq:

dynamic stuff = JObject.Parse("{ 'Name': 'Jon Smith', 'Address': { 'City': 'New York', 'State': 'NY' }, 'Age': 42 }");

string name = stuff.Name;
string address = stuff.Address.City;

文档:使用动态查询JSON

试试这个:

  var units = new { Name = "Phone", Color= "White" };
    var jsonResponse = JsonConvert.DeserializeAnonymousType(json, units);

使用DataSet(c#)和JavaScript。一个创建带有DataSet输入的JSON流的简单函数。创建JSON内容，如(多表数据集):

[[{a:1,b:2,c:3},{a:3,b:5,c:6}],[{a:23,b:45,c:35},{a:58,b:59,c:45}]]

只是客户端，使用eval。例如,

var d = eval('[[{a:1,b:2,c:3},{a:3,b:5,c:6}],[{a:23,b:45,c:35},{a:58,b:59,c:45}]]')

然后使用:

d[0][0].a // out 1 from table 0 row 0

d[1][1].b // out 59 from table 1 row 1

// Created by Behnam Mohammadi And Saeed Ahmadian
public string jsonMini(DataSet ds)
{
    int t = 0, r = 0, c = 0;
    string stream = "[";

    for (t = 0; t < ds.Tables.Count; t++)
    {
        stream += "[";
        for (r = 0; r < ds.Tables[t].Rows.Count; r++)
        {
            stream += "{";
            for (c = 0; c < ds.Tables[t].Columns.Count; c++)
            {
                stream += ds.Tables[t].Columns[c].ToString() + ":'" +
                          ds.Tables[t].Rows[r][c].ToString() + "',";
            }
            if (c>0)
                stream = stream.Substring(0, stream.Length - 1);
            stream += "},";
        }
        if (r>0)
            stream = stream.Substring(0, stream.Length - 1);
        stream += "],";
    }
    if (t>0)
        stream = stream.Substring(0, stream.Length - 1);
    stream += "];";
    return stream;
}

我需要的是返回一个带有不同字段的json模型。 我的模型是这样的，但它可以改变。

{
    "employees":
    [
        { "name": "Darth", "surname": "Vader", "age": "27", "department": "finance"},
        { "name": "Luke", "surname": "Skywalker", "age": "25", "department": "IT"},
        { "name": "Han", "surname": "Solo", "age": "26", "department": "credit"}
    ]
}

获取数据值的列表

    JObject array = JObject.Parse(model.JsonData);
    var tableData = new List<JsonDynamicModel>();

    foreach (var objx in array.Descendants().OfType<JProperty>().Where(p => p.Value.Type != JTokenType.Array && p.Value.Type != JTokenType.Object))
            {
                var name = ((JValue)objx.Name).Value;
                var value = ((JValue)objx.Value).Value;
                if (tableData.FirstOrDefault(x => x.ColumnName == name.ToString()) == null)
                {
                    tableData.Add(new JsonDynamicModel
                    {
                        ColumnName = name.ToString(),
                        Values = new List<string> { value.ToString() },
                    });
                }
                else
                {
                    tableData.FirstOrDefault(x=>x.ColumnName == name.ToString()).Values.Add(value.ToString());
                }
            }

输出如下所示。然后我把结果模型转换成一个html表，我用这个方法创建了一个html表

// output
tableData[0].ColumnName -> "name";
tableData[0].Values -> {"Darth", "Luke", "Han" }
tableData[1].ColumnName -> "surname";
tableData[1].Values -> {"Vader", "Skywalker", "Solo" }
...

我想在单元测试中以编程的方式完成，我可以把它打出来。

我的解决方案是:

var dict = JsonConvert.DeserializeObject<ExpandoObject>(json) as IDictionary<string, object>;

现在我可以断言

dict.ContainsKey("ExpectedProperty");

最简单的方法是:

只需包含这个DLL文件。

像这样使用代码:

dynamic json = new JDynamic("{a:'abc'}");
// json.a is a string "abc"

dynamic json = new JDynamic("{a:3.1416}");
// json.a is 3.1416m

dynamic json = new JDynamic("{a:1}");
// json.a is

dynamic json = new JDynamic("[1,2,3]");
/json.Length/json.Count is 3
// And you can use json[0]/ json[2] to get the elements

dynamic json = new JDynamic("{a:[1,2,3]}");
//json.a.Length /json.a.Count is 3.
// And you can use  json.a[0]/ json.a[2] to get the elements

dynamic json = new JDynamic("[{b:1},{c:1}]");
// json.Length/json.Count is 2.
// And you can use the  json[0].b/json[1].c to get the num.
