Properties

InnerDataReader

Retrieves the underlying IDataReader object that is driving the current data reader.

IsClosed

Retrieves a Boolean value that indicates whether the specified data reader instance has been closed.

ItemCount

Retrieves the number of items in the current block of data.

Status

Retrieves a numerical status code returned by the method currently providing data to the data reader.

Methods

Close()

Closes the current IDataReader 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 as well as 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.

GetItem(Int32)

Retrieves an object instance representing the retrievable item as determined by an index into the current block of data.

GetItem(String)

Retrieves an object instance representing the retrievable item as specified by 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, DataItemTypeFormat)

Returns the data type of a data item, or items, at the specified index in a specified format.

IsNullItem(Int32)

Indicates whether the data item at the specified index is unspecified, that is, null.

NextResult()

Advances the data reader to the next result in cases where the reader contains multiple results.

Read()
