# MultipartFormFileSection

> A helper object for adding file uploads to multipart forms via the [IMultipartFormSection] API.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.Networking](/engine/6000.6/script-reference/unityengine/networking.md)
* **Assembly:** UnityEngine.UnityWebRequestModule
* **Implements:** [IMultipartFormSection](/engine/6000.6/script-reference/unityengine/networking/imultipartformsection.md)

```csharp
public class MultipartFormFileSection : IMultipartFormSection
```

## Remarks

This object is similar to the [MultipartFormDataSection](/engine/6000.6/script-reference/unityengine/networking/multipartformdatasection.md) object, but all constructors additionally accept (and require) a `fileName` parameter. If you omit the `fileName` parameter, this object provides a default filename.
