CopyFromPoco Method

Overview

The CopyFromPoco method copies values from a POCO object into an IObservableDataRow by reading all public instance properties that have a getter. Each readable property value is assigned to the data row field with the same name as the property.

This method does not validate that the POCO structure matches the row schema. For predictable results, ensure that the row contains fields for the POCO properties (for example, by creating the table from an interface and creating the row from the table columns).

Declaration

/// <summary>
/// Copies public readable POCO properties into an observable data row.
/// Matching between property names and existing row keys is case-insensitive.
/// </summary>
/// <typeparam name="T">POCO type</typeparam>
/// <param name="observableDataRow">Target observable data row</param>
/// <param name="pocoInstance">Source POCO instance</param>
public static void CopyFromPoco<T>(this IObservableDataRow? observableDataRow, T? pocoInstance)

Namespace and Assembly

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

Usage Example

Let’s assume there is an interface that defines the employment type:

internal interface IEmploymentType
{
  string Code { get; set; }
  string? Description { get; set; }
  int Id { get; set; }
}

And a class that implements the interface:

internal class EmploymentType
{
  public string Code { get; set; }
  public string? Description { get; set; }
  public int Id { get; set; }
}

Import data from an EmploymentType object into a row:

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

// 2. Create an empty data table from POCO interface and create a new row
IObservableDataTable employmentTypeObservableDataTable = observableDataSet.AddNewTableFromPocoInterface("EmploymentType", typeof(IEmploymentType));
IObservableDataRow employmentTypeDataRow = employmentTypeObservableDataTable.AddNewRow();

// 3. Create POCO object
EmploymentType employmentType = new EmploymentType();
employmentType.Id = 1;
employmentType.Code = "ET01";
employmentType.Description = "Full Time";

// 4. Copy values from POCO instance into the row
employmentTypeDataRow.CopyFromPoco<EmploymentType>(employmentType);
