RemoveRow Method

Overview

The RemoveRow extension method removes a row from a table in an IDataSet.

It is a convenience wrapper over the table-level remove operations. The method locates the table by name and delegates to IDataTable.RemoveRow(...).

Two overloads are provided: remove by row index, and remove by row reference (state-aware semantics).

Declaration

/// <summary>
/// Removes row from table
/// </summary>
/// <param name="dataSet">Data set</param>
/// <param name="tableName">Table name</param>
/// <param name="rowIndex">Row index</param>
/// <exception cref="KeyNotFoundException">Exception is thrown if dataset does not contains a table with specified name</exception>
/// <exception cref="ArgumentOutOfRangeException">Exception is thrown if table does not have row with specified index</exception>
public static void RemoveRow(this IDataSet? dataSet, string tableName, int rowIndex)

/// <summary>
/// Removes row from table using state-aware semantics.
/// </summary>
/// <param name="dataSet">Data set</param>
/// <param name="tableName">Table name</param>
/// <param name="dataRow">Data row to remove</param>
/// <exception cref="KeyNotFoundException">Thrown if dataset does not contain a table with specified name</exception>
public static void RemoveRow(this IDataSet? dataSet, string tableName, IDataRow? dataRow)

Namespace and Assembly

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

Usage Example

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

// 2. Add Department table to data set
IDataTable departmentDataTable = dataSet.AddNewTable("Department");
departmentDataTable.AddColumn("Id", DataTypeNames.INT32, false, true);
departmentDataTable.AddColumn("Name", DataTypeNames.STRING);

// 3. Add two rows to Department table
IDataRow departmentFirstDataRow = departmentDataTable.AddNewRow();
departmentFirstDataRow["Id"] = 1;
departmentFirstDataRow["Name"] = "Sales";

IDataRow departmentSecondDataRow = departmentDataTable.AddNewRow();
departmentSecondDataRow["Id"] = 2;
departmentSecondDataRow["Name"] = "Engineering";

// 4a. Remove by index
dataSet.RemoveRow("Department", 0);

// 4.b. Remove by row reference (state-aware semantics)
dataSet.RemoveRow("Department", departmentSecondDataRow);
