EnumerateValues Method

Overview

The EnumerateValues method returns an enumerable sequence of all field values in a data row as KeyValuePair<string, object?> items, where the key is the field (column) name and the value is the current field value.

This method is a convenience wrapper over IDataRow.Values and can be used to iterate over row fields in a foreach loop.

Declaration

/// <summary>
/// Enumerates values
/// </summary>
/// <param name="dataRow" >Data row</param>
/// <returns>Enumerated values</returns>
public static IEnumerable<KeyValuePair<string, object?>> EnumerateValues(this IDataRow dataRow)

Namespace and Assembly

Namespace: PocoDataSet.Extensions
Assembly: PocoDataSet.Extensions.dll

Usage Example

// 1. Create an empty data set
IDataSet dataSet = DataSetFactory.CreateDataSet();

// 2. Create a table, add columns and a row
IDataTable departmentDataTable = dataSet.AddNewTable("Department");
departmentDataTable.AddColumn("Id", DataTypeNames.INT);
departmentDataTable.AddColumn("Name", DataTypeNames.STRING);

IDataRow departmentDataRow = departmentDataTable.AddNewRow();
departmentDataRow.UpdateFieldValue("Id", 1);
departmentDataRow.UpdateFieldValue("Name", "HR");

// 3. Enumerate all values in the row
foreach (KeyValuePair<string, object?> pair in departmentDataRow.EnumerateValues())
{
  string fieldName = pair.Key;
  object? fieldValue = pair.Value;
}
