public abstract class DataRowReader : IDisposable
The DataRowReader type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
 | Columns | Represents a collection of the columns that the reader returns.
|
| IsClosed |
Gets a value indicating whether the data reader is closed.
|
| ResultProperties | Gets a read-only copy of the result properties, this is properties for the entire
reader result and not for a specific column.
|
Methods
| Name | Description | |
|---|---|---|
 | Close | Closes the data reader.
|
 | CreateReader(IDataReader) |
Creates a DataRowReader from the given IDataReader.
|
| CreateReader(IDataReader, ResultProperties) |
Creates a DataRowReader from the given IDataReader.
|
| CreateReader(IDataReader, IListDataColumnProperties) |
Creates a DataRowReader from the given IDataReader.
|
| CreateReader(IDataReader, IListDataColumnProperties, ResultProperties) |
Creates a DataRowReader from the given IDataReader.
|
| Dispose | Dispose method.
|
  | Dispose(Boolean) | Call when the caller is finished using the data reader.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Releases unmanaged resources and performs other cleanup operations before the
DataReader2 is reclaimed by garbage collection.
(Overrides ObjectFinalize.) |
| GetColumnsCore | The implementor should provide a list of DataRowReaderColumns that it
returns.
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetResultPropertiesCore | The implementor should provide the result properties.
|
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MoveNext | Advances the reader to the next row.
|
| MoveNextCore | Advance to the next row.
The implementor should update all DataValueCursors in the DataRowReaderColumns
with values for the next row.
|
| Reset | Resets the reader so that the next time MoveNext is called
the first row will be returned.
|
| ResetCore | The implementor should implement this method to reset the
enumerator. If this method is called then the MoveNextCore
method should return the first row again when called the next time.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Remarks
It is not possible to inherit directly from this class, this should be done through the CustomDataRowReader class.
