Constructors
| AdoDotNetReader(DbDataReader) |
Initializes a parameterized instance of the AdoDotNetReader class with an ADO.NET data reader object. |
| AdoDotNetReader(DbDataReader, DbCommand) |
Initializes a parameterized instance of the AdoDotNetReader class with an ADO.NET data reader object and a command object. |
Properties
| Descriptor |
Gets information that describes the data from a data source. (Inherited from DataReader) |
| HasDescriptor |
Gets a value indicating whether the data parameter exposes its IVsDataReaderDescriptor implementation through the Descriptor property. |
| IsClosed |
Gets a value indicating whether the specified data reader instance is closed. |
| ItemCount |
Gets the number of items in the current block of data. |
| Status |
Gets a numerical status code returned by the method currently providing data to the data reader. |
| UnderlyingReader |
Gets the underlying DbDataReader object instance that is used by this class. |
Methods
| Close() |
Closes the current DbDataReader object instance. |
| Dispose() |
Releases managed resources held for the current DataReader instance. (Inherited from DataReader) |
| Dispose(Boolean) |
Cleans up resources associated with the current DataReader instance, both when the public Dispose() method is called and when the object is finalized with a call to the Finalize() method. (Inherited from DataReader) |
| GetBytes(Int32, Byte[], Int32, Int32) |
Retrieves a specified number of bytes of binary data. |
| GetBytes(String, Byte[], Int32, Int32) |
Retrieves a specified number of bytes of raw binary data. (Inherited from DataReader) |
| GetItem(Int32) |
Retrieves an object instance representing the retrievable item, as determined by an index in the current block of data. |
| GetItem(String) |
Retrieves an object instance representing the retrievable item as specified by name. |
| GetItemIndex(String) |
Retrieves the index of the item for the given item name, such as the index of a column for a given column name. |
| GetItemMaxLength(Int32) |
Retrieves the maximum length, in characters, of data items at the specified index. |
| GetItemName(Int32) |
Retrieves the name assigned to the data item at the specified index, if any. |
| GetItemType(Int32) |
Retrieves the data type of a data item, or items, at the specified index for the default format Default. (Inherited from DataReader) |
| GetItemType(Int32, DataItemTypeFormat) |
Retrieves the data type of a data item, or items, at the specified index in a specified format. |
| IsNullItem(Int32) |
Indicates whether the value of the data item at the specified index is unspecified, that is, null. |
| IsNullItem(String) |
Indicates whether the value of the given data item is unspecified, that is, null. (Inherited from DataReader) |
| NextResult() |
Advances the data reader to the next result if the reader contains multiple results. |
| Read() |
Advances the reader to the next block of data if the reader contains more than one block. |
| Terminate() |
Terminates the data reader immediately, without necessarily returning all of the data or setting output parameters. |
