I am trying to pass a SQL result from my PHP-made website to my C# APP that I'm making with Xamarin Forms. I've done this by making A REST API endpoint in my PHP application and therefore calling the URL through my C# app. This returns a Json Array with my results. However, I can't find any way to parse the datetime object that I'm receiving to c# datetime as it has ".00000" behind the datetime that i can't get rid of.
SQL
$query = $this->createQueryBuilder('c')
->select('partial c.{id, image, title,contentType, createdOn }', 'partial cd.{id, data}', 'partial u.{id, email} ', 'partial ud.{id, screenName, profileImage} ')
->join('c.data', 'cd')
->join('c.user', 'u')
->join('u.data', 'ud')
->andWhere('c.user !=:user')
->setParameters(
array(
'user' => $this->janVanAllemanId
)
)
->orderBy('c.modifiedOn', 'DESC')
->setFirstResult($offset)
->setMaxResults($limit)
->getQuery();
$results = $query->getArrayResult();
JSON Array
{
"posts": [
{
"id": 3373,
"contentType": 6,
"createdOn": {
"date": "2019-05-21 14:00:14.000000",
"timezone_type": 3,
"timezone": "Europe/Amsterdam"
},
...
},
{
"id": 3371,
"contentType": 6,
"createdOn": {
"date": "2019-05-18 14:30:09.000000",
"timezone_type": 3,
"timezone": "Europe/Amsterdam"
},
...
}
]
}
As you can see it returns an array with "date", "timezone" and "timezone_type". I can not use this to parse it to a C# DateTime object for the life of me.
This is what I've tried:
PostRepository.cs
public class PostRepository : Repository
{
public async Task<List<Post>> GetNotifications(int userId, int offset = 0, int limit = 16)
{
string[] queryParams = { "userId=" + userId, "offset=" + offset, "limit=" + limit };
string uri =
RestService.GetApiUrl(UrlExtension.POST_NOTIFICATIONS, queryParams);
List<Post> posts = new List<Post>();
HttpResponseMessage response = null;
response = await client.GetAsync(uri);
if (response.IsSuccessStatusCode)
{
PostList postList = await response.Content.ReadAsAsync<PostList>();
posts = postList.Posts;
}
return posts as List<Post>;
}
}
PostList.cs
public class PostList
{
[JsonProperty("posts")]
public List<Post> Posts { get; set; }
public PostList()
{
}
}
*Method 1: Through a DateTime property, I tried to deserialize the result.
Post.cs
...
public class Post
{
[JsonProperty("createdOn")]
public DateTime CreatedOnDateTime{get;set;}
}
This obviously does not work, because it's not a valid Datetime object. So I tried a JObject and getting the "date" key that you could see above in my Json array:
Post.cs
...
public class Post
{
public DateTime CreatedOnDateTime {get;set;}
[JsonProperty("createdOn")]
public JObject CreatedOn{
set{
CreatedOnDateTime= DateTime.ParseExact(value["date"].ToString(),
"M/d/yyyy hh:mm",CultureInfo.CreateSpecificCulture("nl-NL"));
}
}
It succesfully converts to a JObject, but it generates an exception saying that it's not a valid string to convert to a datetime object! I mainly think the reason why this doesn't work is because of the .00000 that magically is appearing behind my dates?!
Anyone knows a way to convert my Json results to a C# DateTime? I really appreciate your help!
You can use this one:
CreatedOnDateTime = DateTime.Parse(value["date"].ToString(), CultureInfo.CreateSpecificCulture("nl-NL"));
