Properties
| Descriptor |
When implemented by a class, gets information that describes the data from a data source. |
| IsClosed |
When implemented by a class, gets a Boolean value that indicates whether the specified reader is closed. |
| Status |
When implemented by a class, gets a numerical status code returned by the method currently providing data to the data reader. |
Methods
| Close() |
When implemented by a class, closes the IVsDataReader instance. |
| GetBytes(Int32, Byte[], Int32, Int32) |
When implemented by a class, retrieves a specified number of bytes of raw binary data. |
| GetBytes(String, Byte[], Int32, Int32) |
When implemented by a class, retrieves a specified number of bytes of raw binary data. |
| GetItem(Int32) |
When implemented by a class, retrieves the value of the item at the specified index in the current block of data. |
| GetItem(String) |
When implemented by a class, retrieves the value of a data item with the specified name in the current block of data. |
| IsNullItem(Int32) |
When implemented by a class, indicates whether the data item at the specified index is unspecified, that is, null. |
| IsNullItem(String) |
When implemented by a class, indicates whether the value of the given data item is unspecified, that is, null. |
| NextResult() |
When implemented by a class, advances the data reader to the next result set, in cases where the reader contains multiple result sets. |
| Read() |
When implemented by a class, advances the reader to the next block of data, in cases where the reader contains more than one block of data. |
| Terminate() |
When implemented by a class, terminates the data reader immediately, without necessarily returning all of the data or setting output parameters. |
