先来看看SqlDataAdapter中的所有成员
public sealed class SqlDataAdapter : DbDataAdapter, IDbDataAdapter, IDataAdapter, ICloneable
{
// Events
public event SqlRowUpdatedEventHandler RowUpdated;
public event SqlRowUpdatingEventHandler RowUpdating;
// Methods
public SqlDataAdapter();
public SqlDataAdapter(SqlCommand selectCommand);
private SqlDataAdapter(SqlDataAdapter adapter);
public SqlDataAdapter(string selectCommandText, SqlConnection selectConnection);
public SqlDataAdapter(string selectCommandText, string selectConnectionString);
protected override RowUpdatedEventArgs CreateRowUpdatedEvent(DataRow dataRow, IDbCommand command, StatementType statementType, DataTableMapping tableMapping);
protected override RowUpdatingEventArgs CreateRowUpdatingEvent(DataRow dataRow, IDbCommand command, StatementType statementType, DataTableMapping tableMapping);
protected override void Dispose(bool disposing);
protected override void OnRowUpdated(RowUpdatedEventArgs value);
protected override void OnRowUpdating(RowUpdatingEventArgs value);
IDbCommand IDbDataAdapter.get_DeleteCommand();
IDbCommand IDbDataAdapter.get_InsertCommand();
IDbCommand IDbDataAdapter.get_SelectCommand();
IDbCommand IDbDataAdapter.get_UpdateCommand();
void IDbDataAdapter.set_DeleteCommand(IDbCommand value);
void IDbDataAdapter.set_InsertCommand(IDbCommand value);
void IDbDataAdapter.set_SelectCommand(IDbCommand value);
void IDbDataAdapter.set_UpdateCommand(IDbCommand value);
object ICloneable.Clone();
// Properties
public SqlCommand DeleteCommand { get; set; }
public SqlCommand InsertCommand { get; set; }
public SqlCommand SelectCommand { get; set; }
public SqlCommand UpdateCommand { get; set; }
// Fields
private SqlCommand cmdDelete;
private SqlCommand cmdInsert;
private SqlCommand cmdSelect;
private SqlCommand cmdUpdate;
private SqlCommand internalCmdSelect;
}
其中并没有Fill方法，那么它从哪里来呢？想必是从它的父类DbDataAdapter中继承而来的那就
