[英]How to create objects of JSON text in c#
嗨,我正在使用Web API,並在StreamReader
上獲取結果。 我想將這些StreamReader
轉換為JSON
我正在使用以下代碼:
var response = (HttpWebResponse)request.GetResponse();
using (var stream = response.GetResponseStream())
using (var reader = new StreamReader(stream))
{
JavaScriptSerializer js = new JavaScriptSerializer();
var objText = reader.ReadToEnd();
MyObject myojb = (MyObject)js.Deserialize(objText, typeof(MyObject));
// Response.Write(reader.ReadToEnd());
}
實際的Model模式就是這樣
{
"id": "",
"description": "",
"added_date": "",
"media_type": "",
"contributor": {
"id": ""
},
"aspect": 0,
"image_type": "",
"is_editorial": false,
"is_adult": false,
"is_illustration": false,
"has_model_release": false,
"has_property_release": false,
"releases": [
""
],
"categories": [
{
"id": "",
"name": ""
}
],
"keywords": [
""
],
"assets": {
"small_jpg": {
"height": 0,
"width": 0,
"file_size": 0,
"display_name": "",
"dpi": 0,
"format": "",
"is_licensable": false
},
"medium_jpg": {
"height": 0,
"width": 0,
"file_size": 0,
"display_name": "",
"dpi": 0,
"format": "",
"is_licensable": false
},
"huge_jpg": {
"height": 0,
"width": 0,
"file_size": 0,
"display_name": "",
"dpi": 0,
"format": "",
"is_licensable": false
},
"supersize_jpg": {
"height": 0,
"width": 0,
"file_size": 0,
"display_name": "",
"dpi": 0,
"format": "",
"is_licensable": false
},
"huge_tiff": {
"height": 0,
"width": 0,
"file_size": 0,
"display_name": "",
"dpi": 0,
"format": "",
"is_licensable": false
},
"supersize_tiff": {
"height": 0,
"width": 0,
"file_size": 0,
"display_name": "",
"dpi": 0,
"format": "",
"is_licensable": false
},
"vector_eps": {
"height": 0,
"width": 0,
"file_size": 0,
"display_name": "",
"dpi": 0,
"format": "",
"is_licensable": false
},
"small_thumb": {
"url": "",
"height": 0,
"width": 0
},
"large_thumb": {
"url": "",
"height": 0,
"width": 0
},
"preview": {
"url": "",
"height": 0,
"width": 0
},
"preview_1000": {
"url": "",
"height": 0,
"width": 0
}
},
"models": [
{
"id": ""
}
]
}
模型就是這樣
Image {
id (string),
description (string, optional),
added_date (string, optional),
media_type (string),
contributor (Contributor),
aspect (number, optional),
image_type (string, optional),
is_editorial (boolean, optional),
is_adult (boolean, optional),
is_illustration (boolean, optional),
has_model_release (boolean, optional),
has_property_release (boolean, optional),
releases (array[string], optional),
categories (array[Category], optional),
keywords (array[string], optional),
assets (ImageAssets, optional),
models (array[Model], optional)
}
Contributor {
id (string)
}
Category {
id (string, optional),
name (string, optional)
}
ImageAssets {
small_jpg (ImageSizeDetails, optional),
medium_jpg (ImageSizeDetails, optional),
huge_jpg (ImageSizeDetails, optional),
supersize_jpg (ImageSizeDetails, optional),
huge_tiff (ImageSizeDetails, optional),
supersize_tiff (ImageSizeDetails, optional),
vector_eps (ImageSizeDetails, optional),
small_thumb (Thumbnail, optional),
large_thumb (Thumbnail, optional),
preview (Thumbnail, optional),
preview_1000 (Thumbnail, optional)
}
ImageSizeDetails {
height (integer, optional),
width (integer, optional),
file_size (integer, optional),
display_name (string, optional),
dpi (integer, optional),
format (string, optional),
is_licensable (boolean, optional)
}
Thumbnail {
url (string),
height (integer),
width (integer)
}
Model {
id (string)
}
但我不知道如何創建對象以獲取JSON
結果。我正在嘗試Myobject
類,但收到錯誤:
數組反序列化不支持類型“ System.String”。
請幫助我如何獲取JSON
結果。謝謝。
可以使用JSON.NET解析json結果:
var data = JsonConvert.DeserializeObject<Rootobject>(data);
使用這種方法,您不需要完全反序列化JSON對象
更新時間 :
var objText = reader.ReadToEnd();
var data = JsonConvert.DeserializeObject<Rootobject>(objText);
PS :我在Visual Studio中使用粘貼JSON作為類來生成模型,或者可以使用json2csharp創建類。
使用json2csharp
您可以從json文本創建模型類。我復制了您的json文本,我得到的輸出是在類下面。

使用Json.Net
您可以使用以下代碼將json文本反序列化為對象
var objText = reader.ReadToEnd();
var myojb = JsonConvert.DeserializeObject<RootObject>(objText);
有關更多信息,請檢查使用Json.NET序列化和反序列化JSON。
