Clear Method
As the name of the method Clear suggests, it clears observable data set by removing all rows from all tables but keeps data set schema (tables and their columns) intact.

// 1. Create observable data set
IObservableDataSet observableDataSet = new ObservableDataSet();
// 2. Create Department observable data table with one row
IObservableDataTable departmentObservableDataTable = observableDataSet.AddNewTable("Department");
departmentObservableDataTable.AddColumn("Id", DataTypeNames.INT32);
departmentObservableDataTable.AddColumn("Name", DataTypeNames.STRING);
IObservableDataRow departmentObservableDataRow = departmentObservableDataTable.AddNewRow();
departmentObservableDataRow.UpdateDataFieldValue("Id", 1);
departmentObservableDataRow.UpdateDataFieldValue("Name", "Customer Service");
// 3. Call Clear method and observe that Department observable data table has no rows anymore
