# Documentation: DTS.DASLib.Service Namespace

## 1. Purpose

This module provides service-layer functionality for DTS SLICE data acquisition hardware. It contains a generic XML-serializable dictionary implementation (`SerializableDictionary<TKey, TValue>`) for persisting key-value data, a partial `Slice<T>` class implementing device information querying via the `IInformationActions` interface, and localized resource strings for error messaging and status reporting. The module serves as an intermediary between hardware communication layers and application-level configuration, calibration, and data collection operations.

## 2. Public Interface

### SerializableDictionary<TKey, TValue>

**Signature:** `public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable`

A generic dictionary class that implements `IXmlSerializable` to enable XML serialization of key-value pairs. Standard `Dictionary<TKey, TValue>` does not support XML serialization directly.

| Method | Signature | Description |
|--------|-----------|-------------|
| `GetSchema` | `public System.Xml.Schema.XmlSchema GetSchema()` | Returns `null`. Required by `IXmlSerializable` interface. |
| `ReadXml` | `public void ReadXml(System.Xml.XmlReader reader)` | Deserializes dictionary contents from XML. Expects elements structured as `<SerializedDictionary><Item><Key>...</Key><Value>...</Value></Item>...</SerializedDictionary>`. Handles empty elements and end-of-stream conditions. |
| `WriteXml` | `public void WriteXml(System.Xml.XmlWriter writer)` | Serializes dictionary contents to XML. Writes a complete XML document with root element `<SerializedDictionary>` containing `<Item>` children, each with `<Key>` and `<Value>` sub-elements. |

### Slice<T> (Partial Class - Information Region)

**Signature:** `public partial class Slice<T> : Communication<T>, IDASCommunication, IConfigurationActions, ICalibrateActions, ITriggerCheckActions, IRealTimeActions, IArmActions, IDownloadActions, IInformationActions where T : IConnection, new()`

A partial class providing SLICE device communication and control. The `Information` region implements device querying functionality.

| Method | Signature | Description |
|--------|-----------|-------------|
| `Query` (explicit interface) | `void IInformationActions.Query(ServiceCallback callback, object userData)` | Launches an asynchronous worker to query device information. Creates a `SliceServiceAsyncInfo` wrapper and delegates to `AsyncQueryInformation`. |
| `AsyncQueryInformation` | `private void AsyncQueryInformation(object asyncInfo)` | Executes synchronous stack query via `QueryStackContents`, builds `InfoResult` with module metadata (serial numbers, gains, sample rates, channel counts), and stores result in `DASInfo` property. Handles `CanceledException` and general exceptions via the async info wrapper. |
| `DASFactoryQueryInformation` | `private void DASFactoryQueryInformation()` | **Note:** Appears to be a duplicate/alternate implementation using `StackContentsQuery` instead of `QueryStackContents`. Contains a bug (references undefined `info` variable). Purpose unclear from source alone. |

### Resources (Internal Class)

**Signature:** `internal class Resources`

Auto-generated strongly-typed resource accessor for localized strings in the `DTS.DASLib.Service` namespace.

| Property | Type | Description |
|----------|------|-------------|
| `ResourceManager` | `global::System.Resources.ResourceManager` | Cached ResourceManager instance for the assembly. |
| `Culture
