TryGetTable Method

Overview

The TryGetTable method attempts to retrieve a table from an IDataSet by name without throwing exceptions. It follows the familiar "TryGet" pattern and returns a boolean indicating success.

In addition to a direct key lookup, the method performs a fallback case-insensitive scan of the table names, which makes it resilient to casing differences between producers and consumers.

Declaration

/// <summary>
/// Tries to get table from dataset by its name
/// </summary>
/// <param name="dataSet">Data set</param>
/// <param name="tableName">Table name</param>
/// <param name="table">Specified table</param>
/// <returns>True if table found, otherwise false</returns>
public static bool TryGetTable(this IDataSet? dataSet, string? tableName, out IDataTable? table)

Namespace and Assembly

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

Behavior

• If dataSet is null, returns false.
• If tableName is null or whitespace, returns false.
• Attempts a fast dictionary lookup using the exact table name.
• If not found, performs a case-insensitive scan of table names.
• If a match is found, assigns the table to the out parameter and returns true.

Usage Example

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

// 2. Create a table
IDataTable departmentTable = dataSet.AddNewTable("Department");

// 3. Try to retrieve the table safely
if (dataSet.TryGetTable("department", out IDataTable? foundTable))
{
  // foundTable is not null
}
