Constructors
| AdoDotNetSchemaReader(DbDataReader, DbCommand) |
Initializes a new instance of the AdoDotNetSchemaReader class with a data reader object and a data command object. |
| AdoDotNetSchemaReader(DbDataReader) |
Initializes a new instance of the AdoDotNetSchemaReader class with a data reader 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. |
| IsClosed |
Gets a value indicating whether the AdoDotNetSchemaReader is closed. |
| ItemCount |
Gets an integer value specifying the number of data items contained in the current AdoDotNetSchemaReader instance. |
| SchemaTable |
Gets the DataTable object that represents the schema of the DbDataReader passed into the constructor of the AdoDotNetSchemaReader. |
| Status |
Gets a numerical status code returned by the method currently providing data to the DataReader object. |
Methods
| Close() |
Closes the current AdoDotNetSchemaReader 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) |
Reads a stream of bytes into the buffer as an array, starting at a specified offset. |
| GetBytes(String, Byte[], Int32, Int32) |
Retrieves a specified number of bytes of raw binary data. (Inherited from DataReader) |
| GetItem(Int32) |
Retrieves a data item at a specified index. |
| GetItem(String) |
Retrieves a data item with a specified 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 an integer value specifying the maximum length of the data item at the specified index. |
| GetItemName(Int32) |
Retrieves the string literal name of the data item at the specified index. |
| GetItemType(Int32, DataItemTypeFormat) |
Retrieves the data type for a data item at a specified index and with a specified item type format. |
| GetItemType(Int32) |
Retrieves the data type of a data item, or items, at the specified index for the default format Default. (Inherited from DataReader) |
| IsNullItem(Int32) |
Retrieves a Boolean value indicating whether the data item at the specified index is null. |
| IsNullItem(String) |
Retrieves a Boolean value indicating whether the data item value for the specified data item name is null. |
| NextResult() |
Tests whether there is another result set and, if true, advances the AdoDotNetSchemaReader. |
| Read() |
Tests whether there is another data record and, if true, advances the AdoDotNetSchemaReader to the next record. |
| Terminate() |
Terminates the DataReader object immediately, without necessarily returning all of the data or setting output parameters. |
