Json数据:

{
"dataSet": {

"header": {

"returnCode": "0",

"errorInfo": "HTTP请求错误",

"version": "V1.0R010",

"totalRows": "2000",

"returnRows": "20"

},

"fieldDefine": {

"assetId": "string",

"serverIdcId": "int",

"inputTime": "datetime"

},

"data": {

"row": [

{

"AssetId": "TCNS2006888",

"ServerIdcId": "1",

"InputTime": "2008-12-12"

},

{

"AssetId": "TCNS2006889",

"ServerIdcId": "2",

"InputTime": "2008-1-1"

}

]

}

}

}

问题:如何获取header中的数据行,以便显示在界面上?                                                 

效果图:                               

将json数据转成dictionary的代码:

/// <summary>

/// 将json数据反序列化为Dictionary

/// </summary>

/// <param name="jsonData">json数据</param>

/// <returns></returns>

private Dictionary<string, object> JsonToDictionary(string jsonData)

{

//实例化JavaScriptSerializer类的新实例

JavaScriptSerializer jss = new JavaScriptSerializer();

try

{

//将指定的 JSON 字符串转换为 Dictionary<string, object> 类型的对象

return jss.Deserialize<Dictionary<string, object>>(jsonData);

}

catch (Exception ex)

{

throw new Exception(ex.Message);

}

}

使用方法:

private void button1_Click(object sender, EventArgs e)

{

//Json数据

string json = "{\"dataSet\":{\"header\":{\"returnCode\":\"0\",\"errorInfo\":\"HTTP请求错误\",\"version\":\"V1.0R010\",\"totalRows\":\"2000\",\"returnRows\":\"20\"},\"fieldDefine\":{\"assetId\":\"string\",\"serverIdcId\":\"int\",\"inputTime\":\"datetime\"},\"data\":{\"row\":[{\"AssetId\":\"TCNS2006888\",\"ServerIdcId\":\"1\",\"InputTime\":\"2008-12-12\"},{\"AssetId\":\"TCNS2006889\",\"ServerIdcId\":\"2\",\"InputTime\":\"2008-1-1\"}]}}}";

Dictionary<string, object> dic = JsonToDictionary(json);//将Json数据转成dictionary格式

Dictionary<string, object> dataSet=(Dictionary<string, object>)dic["dataSet"];

//使用KeyValuePair遍历数据

foreach (KeyValuePair<string, object> item in dataSet)

{

if (item.Key.ToString() == "header")//获取header数据

{

var subItem=(Dictionary<string,object>)item.Value;

foreach (var str in subItem)

{

textBox1.AppendText(str.Key + ":" + str.Value+"\r\n");//显示到界面

}

break;

}

}

}
