AddNewTableFromPocoInterface Method

Overview

The AddNewTableFromPocoInterface method adds a new IObservableDataTable to an IObservableDataSet and builds the table schema by reflecting over a POCO interface type. It creates the table, assigns the table name, adds it to the data set, and then calls AddColumnsFromInterface(Type) to populate column metadata based on the interface properties.

Declaration

/// <summary>
/// Adds a new observable table to observable data set using POCO interface type (delegates to inner data set)
/// </summary>
/// <typeparam name="TInterface">Interface type</typeparam>
/// <param name="observableDataSet">Observable data set</param>
/// <param name="tableName">Table name</param>
/// <param name="interfaceType">Interface type</param>
/// <returns>New observable table</returns>
/// <exception cref="KeyDuplicationException">Exception is thrown if dataset contains a table with specified name already</exception>
public static IObservableDataTable AddNewTableFromPocoInterface(this IObservableDataSet? observableDataSet, string tableName, Type interfaceType)

Namespace and Assembly

Namespace: PocoDataSet.ObservableExtensions
Assembly: PocoDataSet.ObservableExtensions.dll

Usage Example

Assume there is an interface that describes the schema of an EmploymentType entity:

/// <summary>
/// Defines employment type functionality
/// </summary>
internal interface IEmploymentType
{
  string Code { get; set; }
  string? Description { get; set; }
  int Id { get; set; }
}

You can create a table with schema based on this interface in a single call:

// 1. Create an observable data set
IObservableDataSet observableDataSet = new ObservableDataSet();

// 2. Create observable data table with schema loaded from POCO interface
IObservableDataTable employmentTypeObservableDataTable = observableDataSet.AddNewTableFromPocoInterface("EmploymentType", typeof(IEmploymentType));
