CopyFromPoco Method

Overview

The CopyFromPoco method copies values from a POCO object into an IDataRow 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 using AddNewTableFromPocoInterface extension method of DataSet and creating the row from the table columns using AddNewRow extension method of DataTable).

Declaration

/// <summary>
/// Copies public readable properties from a POCO into a data row.
/// Matching between property names and existing row keys is case-insensitive.
/// If a matching key exists (ignoring case), the existing key is updated to avoid duplicates.
/// If no matching key exists, a new key is added using the property name.
/// </summary>
/// <typeparam name="T">POCO type.</typeparam>
/// <param name="dataRow">Target data row.</param>
/// <param name="poco">Source POCO instance.</param>
public static void CopyFromPoco<T>(this IDataRow? dataRow, T poco)

Namespace and Assembly

Namespace: PocoDataSet.Extensions
Assembly: PocoDataSet.Extensions.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 data set
IDataSet dataSet = DataSetFactory.CreateDataSet();

// 2. Create EmploymentType data table from POCO interface and add a new row to it
IDataTable employmentTypeDataTable = dataSet.AddNewTableFromPocoInterface("EmploymentType", typeof(IEmploymentType));
IDataRow employmentTypeDataRow = employmentTypeDataTable.AddNewRow();

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

// 4. Copy values into the row
employmentTypeDataRow.CopyFromPoco(employmentType);
