> A helper object for form sections containing generic, non-file data.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.Networking](/engine/6000.5/script-reference/unityengine/networking.md)
* **Assembly:** UnityEngine.UnityWebRequestModule
* **Implements:** [IMultipartFormSection](/engine/6000.5/script-reference/unityengine/networking/imultipartformsection.md)

```csharp

```

## Remarks

This helper object is used similarly to the [WWWForm](/engine/6000.5/script-reference/unityengine/wwwform.md) method [WWWForm.AddBinaryData](/engine/6000.5/script-reference/unityengine/wwwform/addbinarydata.md). It is used to define non-file form sections.
