- It handles missing json properties quite well (it will automatically convert to nullable types when it recognises properties not repeated in the arrays of objects). Of course having a c# converter class would not make sense if the json was completely irregular/randomic. In those situations, using dynamic is the way to go.
- Nowadays, we are dealing with JSON data mostly when receiving data in JSON format from a web service and getting data from it. To accomplish getting data from JSON or creating JSON text from a custom object we will use JSON serialization and deserialization in C#.

I have a JSON string and I need some help to deserialize it.
Nothing worked for me.. This is the JSON:
I have an example of the classes, but I don't have to use those classes. I don't mind using some other classes.
These are the classes:
I want to mention that I have Newtonsoft.Json already, so I can use some functions from there. Shoutcast winamp plugin download.
How can I do this?

I am using like this in my code and it's working fine

Should just be this:
You can paste the json string to here: http://json2csharp.com/ to check your classes are correct.

If you use C# 2010 or newer, you can use dynamic type:
Then you can access attributes and arrays in dynamic object using dot notation: Q messenger app att.

First install

newtonsoft.json
package to Visual Studio
using NuGet Package Manager
then add the following code:

I had a scenario, and this one helped me
JObject
objParserd = JObject
.Parse(jsonString);
JObject
arrayObject1 = (JObject
)objParserd['d'];
D
myOutput= JsonConvert
.DeserializeObject<D>
(arrayObject1.ToString());

I solved this problem to add a public setter for all properties, which should be deserialized.

You can solve your problem like below bunch of codes

I also had the issue of parsing and using JSON objects in C#. I checked the dynamic type with some libraries, but the issue was always checking if a property exists.
In the end, I stumbled upon this web page, which saved me a lot of time. It automatically creates a strongly typed class based on your JSON data, that you will use with the Newtonsoft library, and it works perfectly. It also works with languages other than C#.

Description
The
ConvertTo-Json
cmdlet converts any object to a string in JavaScript Object Notation (JSON)format. The properties are converted to field names, the field values are converted to propertyvalues, and the methods are removed.
You can then use the
ConvertFrom-Json
cmdlet to convert a JSON-formatted string to a JSONobject, which is easily managed in PowerShell.
Many web sites use JSON instead of XML to serialize data for communication between servers andweb-based apps.
This cmdlet was introduced in Windows PowerShell 3.0.
Examples
Example 1
This command uses the
ConvertTo-Json
cmdlet to convert a GregorianCalendar object to aJSON-formatted string.
Example 2
This example shows the output from
ConvertTo-Json
cmdlet with and without the -AsArray
switchparameter. You can see the second portion of the output is wrapped in array brackets.
Example 3
This command shows the effect of using the
-Compress
parameter of ConvertTo-Json
. Thecompression affects only the appearance of the string, not its validity.
Example 4
This example uses the
ConvertTo-Json
cmdlet to convert a System.DateTime object from theGet-Date
cmdlet to a JSON-formatted string. The command uses the Select-Object
cmdlet to getall (*
) of the properties of the DateTime object. The output shows the JSON string thatConvertTo-Json
returned.
Example 5
This example shows how to use the
ConvertTo-Json
and ConvertFrom-Json
cmdlets to convert anobject to a JSON string and a JSON object.
Parameters
-AsArray
![Json Json](/uploads/1/2/4/9/124957638/152755162.png)
Outputs the object in array brackets, even if the input is a single object.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Omits white space and indented formatting in the output string.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Specifies how many levels of contained objects are included in the JSON representation. The defaultvalue is 2.
Type: | Int32 |
Position: | Named |
Default value: | 2 |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Provides an alternative serialization option that converts all enumerations to their string representation.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Controls how certain characters are escaped in the resulting JSON output. By default, only controlcharacters (e.g. newline) are escaped.
Type: | NewtonSoft.Json.StringEscapeHandling |
Position: | Named |
Default value: | Default |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Serialize Object To Json File
Specifies the objects to convert to JSON format. Enter a variable that contains the objects, or typea command or expression that gets the objects. You can also pipe an object to
ConvertTo-Json
.
The InputObject parameter is required, but its value can be null (
$null
) or an empty string.When the input object is $null
, ConvertTo-Json
does not generate any output. When the inputobject is an empty string, ConvertTo-Json
returns an empty string.
Type: | Object |
Position: | 0 |
Default value: | None |
Accept pipeline input: | True (ByValue) |
Accept wildcard characters: | False |
Inputs
System.Object
You can pipe any object to
ConvertTo-Json
.
Outputs
System.String
Notes
Java Json Serializer
The
ConvertTo-Json
cmdlet is implemented using Newtonsoft Json.NET.
