AddTable Method

Overview

The AddTable method adds an existing data table instance into a data set. Unlike AddNewTable, it does not create a table; it inserts a table that has already been created by the caller.

The method requires that the provided table has a non-empty TableName and that the data set does not already contain a table with the same name.

Declaration

/// <summary>
/// Adds table to data set
/// </summary>
/// <param name="dataSet">Data set</param>
/// <param name="tableName">Table name</param>
/// <exception cref="ArgumentException">Exception is thrown if specified table does not have assigned name</exception>
/// <exception cref="KeyDuplicationException">Exception is thrown if a dataset contains a table with specified name already</exception>
public static void AddTable(this IDataSet? dataSet, IDataTable dataTable)

Namespace and Assembly

Namespace: PocoDataSet.Data
Assembly: PocoDataSet.Data.dll

Behavior

• If dataSet is null, returns immediately.
• If dataTable.TableName is null or empty, throws ArgumentException.
• If dataSet.Tables already contains a table with that name, throws KeyDuplicationException.
• Otherwise, the method inserts the table into dataSet.Tables using the table name as the dictionary key.

Usage Example

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

// 2) Create a table and assign a name
IDataTable departmentDataTable = new DataTable();
departmentDataTable.TableName = "Department";

// 3) Build schema / rows as needed
departmentDataTable.AddColumn("Id", DataTypeNames.INT32);
departmentDataTable.AddColumn("Name", DataTypeNames.STRING);

// 4) Add the table into the data set
dataSet.AddTable(departmentDataTable);
