## Inheritance

[Object](https://learn.microsoft.com/dotnet/api/system.object) → [ValueType](https://learn.microsoft.com/dotnet/api/system.valuetype) → [Enum](https://learn.microsoft.com/dotnet/api/system.enum) → **OpcEncodingType**

## Fields

| Name | Value | Description |
|---|---|---|
| <a id="binary"></a>`Binary` | `0` | Encodes information using its binary representation 'byte-by-byte' according their endianess. This type of encoding additionally uses meta-fields (within the binary data-stream) to identify for example the number of characters in a [string](https://learn.microsoft.com/dotnet/api/system.string) or the number of items in an array. The resulting binary data-stream is transported with the most less effort in comparison will all supported encoding types. |
| <a id="xml"></a>`Xml` | `1` | Encodes information using XML-based data-serialization. The thereby [string](https://learn.microsoft.com/dotnet/api/system.string)-based representation of the information encoded describes the transported data in a human readable way. |
