示例1: Main
public static void Main()
{
try
{
DataTable userTable = new DataTable("peopleTable");
userTable.Columns.Add("Id", typeof(int));
userTable.Columns.Add("Name", typeof(string));
// Note that even if you create the DataTableReader
// before adding the rows, the enumerator can still
// visit all the rows.
DataTableReader reader = userTable.CreateDataReader();
userTable.Rows.Add(new object[] { 1, "Peter" });
userTable.Rows.Add(new object[] { 2, "Mary" });
userTable.Rows.Add(new object[] { 3, "Andy" });
userTable.Rows.Add(new object[] { 4, "Russ" });
IEnumerator enumerator = reader.GetEnumerator();
// Keep track of whether the row to be deleted
// has actually been deleted yet. This allows
// this sample to demonstrate that the enumerator
// is able to survive row deletion.
bool isRowDeleted = false;
while (enumerator.MoveNext())
{
DbDataRecord dataRecord = (DbDataRecord)enumerator.Current;
// While the enumerator is active, delete a row.
// This doesn't affect the behavior of the enumerator.

}
Console.WriteLine(dataRecord.GetString(1));
