Answer 1

The class DataSet directly supports merging data in the form of DataRow or DataTable. Query for your DataSet object and perform whatever operations you require.

public void Merge(DataRow[] rows, bool preserveChanges, MissingSchemaAction missingSchemaAction);
public void Merge(DataRow[] rows);
public void Merge(DataTable table, bool preserveChanges, MissingSchemaAction missingSchemaAction);
public void Merge(DataSet dataSet, bool preserveChanges, MissingSchemaAction missingSchemaAction);
public void Merge(DataSet dataSet);
public void Merge(DataSet dataSet, bool preserveChanges);

Answer 2

You could try something like this:

DataSet dataSet = new DataSet("DataSetName");
dataSet.Tables.Add("TableName");

var tableIndex = dataSet.Tables.IndexOf("TableName");
dataSet.Tables[tableIndex].Rows.Add(someDataRow);
