## Constructors

| Name | Description |
|---|---|
| [ByteString](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#bytestring) | Initializes a new ByteString from the `value` specified. |

## Properties

| Name | Description |
|---|---|
| [Length](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#length) | Gets the total number of elements in all the dimensions of the ByteString. |

## Methods

| Name | Description |
|---|---|
| [CompareTo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#compareto)<span class="api-meta">2 overloads</span> | Compares the current ByteString with the `other`. |
| [Equals](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#equals)<span class="api-meta">2 overloads</span> | Determines whether the specified `other` is equal to this ByteString. |
| [GetHashCode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#gethashcode)<span class="api-meta">override</span> | Retrieves a hash code for this ByteString. |
| [Parse](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#parse)<span class="api-meta">static</span> | Converts the specified hex encoded byte array to its ByteString equivalent. |
| [ToArray](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#toarray)<span class="api-meta">since v2.18</span> | Copies the [byte](https://learn.microsoft.com/dotnet/api/system.byte) values of the ByteString to a new array. |
| [ToString](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#tostring)<span class="api-meta">override</span> | Converts the value of this instance to its equivalent hex encoded string representation. |
| [TryParse](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/members#tryparse)<span class="api-meta">static</span> | Tries to convert the specified hex encoded byte array to its ByteString equivalent. |

## Operators
