# Class NewtonsoftDynamicParameterConverter

OptimaJet.Workflow.Core.Model.NewtonsoftDynamicParameterConverter

Provides a JsonConverter that converts [DynamicParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/) values to and from JSON by using [DynamicParameter.SerializeToJson()](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/) and [DynamicParameter.ParseJson(JToken)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/), respectively.

Namespace: [OptimaJet.Workflow.Core.Model](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/)

```csharp
public class NewtonsoftDynamicParameterConverter : JsonConverter
```

## Type Hierarchy

-   JsonConverter
    -   NewtonsoftDynamicParameterConverter Current type

## Methods

`public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)` 

Writes the JSON representation returned by [DynamicParameter.SerializeToJson()](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `writer` | `JsonWriter` | The JsonWriter that receives the JSON value. |
| `value` | `Object` | The [DynamicParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/) to serialize. Any other value is written as JSON [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null). |
| `serializer` | `JsonSerializer` | The JsonSerializer performing the serialization; this converter does not use it. |

`public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)` 

Reads a JSON value and converts it through [DynamicParameter.ParseJson(JToken)](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `reader` | `JsonReader` | The JsonReader positioned at the value to read. |
| `objectType` | `Type` | The target [Type](https://learn.microsoft.com/dotnet/api/system.type); this converter does not use it. |
| `existingValue` | `Object` | The existing value; this converter does not use it. |
| `serializer` | `JsonSerializer` | The JsonSerializer performing the deserialization; this converter does not use it. |

### Returns

| Type | Description |
| --- | --- |
| `Object` | A scalar or collection value for the corresponding JSON value; a [DynamicParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/) for a JSON object; or [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) for a JSON null value. |

`public override bool CanConvert(Type objectType)` 

Determines whether `objectType` is exactly [DynamicParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `objectType` | `Type` | The [Type](https://learn.microsoft.com/dotnet/api/system.type) to evaluate. |

### Returns

| Type | Description |
| --- | --- |
| `Boolean` | [true](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool) if `objectType` is exactly [DynamicParameter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Model/DynamicParameter/); otherwise, [false](https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool). |
