TryGetTable Method

Overview

Attempts to retrieve an IObservableDataTable by name without throwing. This is the safe alternative to the indexer when the table may or may not be present (for example, a server response that conditionally includes a table).

Declaration

/// <summary>
/// Attempts to retrieve the data table associated with the specified table name
/// IObservableDataSet interface implementation
/// </summary>
/// <param name="tableName">The name of the table to retrieve</param>
/// <param name="dataTable">When this method returns true, contains the data table associated with the specified table name, otherwise null</param>
/// <returns>True if a table with the specified name was found, otherwise false</returns>
public bool TryGetTable(string tableName, out IObservableDataTable? dataTable)

Namespace and Assembly

Namespace: PocoDataSet.ObservableData
Assembly: PocoDataSet.ObservableData.dll

Usage Example

// 1. Create observable dataset
IObservableDataSet observableDataSet = new ObservableDataSet();

// 2. Add Customer observable data table to observable dataset
IObservableDataTable customerObservableDataTable = observableDataSet.AddNewTable("Customer");

// 3. Try to get Customer table and observe that it is present in the observable dataset
bool customerTableExists = observableDataSet.TryGetTable("Customer", out IObservableDataTable? customer))

// 4. Try to get Employee table and observe that it is not present in the observable dataset
