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 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 of the inner data row
/// </summary>
/// <param name="observableDataRow">Observable data row</param>
/// <returns>Enumerated values as (ColumnName, Value) pairs</returns>
public static IEnumerable<KeyValuePair<string, object?>> EnumerateValues(this IObservableDataRow dataRow)

Namespace and Assembly

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

Usage Example

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

// 2. Create observable table and row
IObservableDataTable departmentObservableDataTable = observableDataSet.AddNewTable("Department");
departmentObservableDataTable.AddColumn("Id", DataTypeNames.INT32, false, true);
departmentObservableDataTable.AddColumn("Name", DataTypeNames.STRING);

IObservableDataRow departmentObservableDataRow = departmentObservableDataTable.AddNewRow();
departmentObservableDataRow["Id"] = 1;
departmentObservableDataRow["Name"] = "Sales";

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