# Class SystemStringEnumConverter<T>

OptimaJet.Workflow.Core.Designer.SystemStringEnumConverter<T>

Converts JSON strings to and from enumeration values of type `T`. Deserialization parses enumeration names without regard to case, while serialization uses [Enum.ToString()](https://learn.microsoft.com/dotnet/api/system.enum.tostring#system-enum-tostring).

        -   SystemStringEnumConverter<T> Current type

## Methods

`public override T Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)` 

Reads a JSON string and parses it as an enumeration value of type `T` without regard to case.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `reader` | `Utf8JsonReader` | The [Utf8JsonReader](https://learn.microsoft.com/dotnet/api/system.text.json.utf8jsonreader) positioned at the value to read. |
| `typeToConvert` | `Type` | The [Type](https://learn.microsoft.com/dotnet/api/system.type) being converted. |
| `options` | `JsonSerializerOptions` | The [JsonSerializerOptions](https://learn.microsoft.com/dotnet/api/system.text.json.jsonserializeroptions) for the current deserialization operation. |

### Returns

| Type | Description |
| --- | --- |
| `{T}` | The enumeration value parsed from the JSON string. |

### Exceptions

| Type | Description |
| --- | --- |
| `JsonException` | The current token is not [JsonTokenType.String](https://learn.microsoft.com/dotnet/api/system.text.json.jsontokentype#system-text-json-jsontokentype-string), or its value cannot be parsed as `T`. |

`public override void Write(Utf8JsonWriter writer, T value, JsonSerializerOptions options)` 

Writes an enumeration value as a JSON string containing the result of [Enum.ToString()](https://learn.microsoft.com/dotnet/api/system.enum.tostring#system-enum-tostring).

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `writer` | `Utf8JsonWriter` | The [Utf8JsonWriter](https://learn.microsoft.com/dotnet/api/system.text.json.utf8jsonwriter) to which the value is written. |
| `value` | `{T}` | The enumeration value to write. |
| `options` | `JsonSerializerOptions` | The [JsonSerializerOptions](https://learn.microsoft.com/dotnet/api/system.text.json.jsonserializeroptions) for the current serialization operation. |
