[英]How to convert HttpResponseMessage having OData to a C# object?
I am calling a REST service from my C# application which connects to CRM. 我从连接到CRM的C#应用程序调用REST服务。 This returns HttpResponseMessage. 这将返回HttpResponseMessage。
response.Content.ReadAsStringAsync().Result
The above statement returns following output. 以上语句返回以下输出。 I need to convert this to Account object, which already has "accountnumber, and accountid properties. 我需要将其转换为Account对象,它已经具有“accountnumber和accountid属性。
{ {
"@odata.context":" https://APIURL/api/data/v8.1/ $metadata#account(accountnumber)","value":[ { "@odata.etag":"W/\\"12496866\\"","accountnumber":"D00208","accountid":"30417c0f-7b8c-e611-80f3-5065f38bd4d1" } ] } “@ odata.context”:“ https://APIURL/api/data/v8.1/ $ metadata#account(accountnumber)”,“value”:[{“@ odata.etag”:“W / \\”12496866 \\“”,“accountnumber”:“D00208”,“accountid”:“30417c0f-7b8c-e611-80f3-5065f38bd4d1”}]}
I have tried following code 我试过以下代码
Account return = JsonConvert.DeserializeObject<Account>(response.Content.ReadAsStringAsync().Result);
But this doesn't fill up the object, and it always has null values in accountnumber, and accountid fields. 但是这不会填满对象,并且它在accountnumber和accountid字段中始终具有空值。
Any idea of how to properly convert this response to the C# type. 知道如何正确地将此响应转换为C#类型。
you should do it like this - 你应该这样做 -
public class Value
{
[JsonProperty("@odata.etag")]
public string etag { get; set; }
public string accountnumber { get; set; }
public string accountid { get; set; }
}
public class RootObject
{
[JsonProperty("@odata.context")]
public string context { get; set; }
public List<Value> value { get; set; }
}
then deserialize- 然后反序列化 -
var value = JsonConvert.DeserializeObject<RootObject>(json);
We can parse and create Anonymous Type
based on that. 我们可以基于此解析并创建Anonymous Type
。 In your case, replace the Anonymous Type
with Account
object. 在您的情况下,将Anonymous Type
替换为Account
对象。
Given the JSON string: 给定JSON字符串:
string json = @"{
'@odata.context':'https://APIURL/api/data/v8.1/$metadata#account(accountnumber)',
'value':[
{
'@odata.etag':'W/\'12496866\'',
'accountnumber':'D00208',
'accountid':'30417c0f-7b8c-e611-80f3-5065f38bd4d1'
}
]
}";
It can be parsed as below: 它可以解析如下:
var jsonObject = JObject.Parse(json);
var dataObject = new
{
Context = jsonObject["@odata.context"],
Values = jsonObject["value"].AsEnumerable<JToken>()
.Select(v => new
{
ETag = v["@odata.etag"],
AccountNumber = v["accountnumber"],
AccountId = v["accountid"]
}).ToArray()
};
In order to convert to Account
object where the object is defined as below: 为了转换为Account
对象,其中对象定义如下:
public class Account
{
public string Number { get; set; }
public string Id { get; set; }
}
Then the JSON
object can be parsed as below (if looking for only first node; It can also be converted to list of Account
s: 然后可以如下解析JSON
对象(如果只查找第一个节点;它也可以转换为Account
的列表:
var jsonObject = JObject.Parse(json);
var account = jsonObject["value"].AsEnumerable<JToken>()
.Select(v => new Account()
{
Number = v["accountnumber"].ToString(),
Id = v["accountid"].ToString()
}).FirstOrDefault();
You can generalize the accepted answer by using a generic class to deserialize json web response: 您可以使用泛型类对json Web响应进行反序列化来概括接受的答案:
class RootObject<T>
{
public List<T> Value { get; set; }
}
var odata = JsonConvert.DeserializeObject<RootObject<POCO>>(json);
