The AdoDotNetDataTableReader type exposes the following members.
Constructors
Name | Description | |
---|---|---|
AdoDotNetDataTableReader(DataTable) | Class constructor. Initializes a parameterized instance of the AdoDotNetDataTableReader class along with a DataTable instance. | |
AdoDotNetDataTableReader(DataTable, Int32) | Class constructor. Initializes a new instance of the AdoDotNetDataTableReader class along with a DataTable instance and a Status indicator. |

Properties
Name | Description | |
---|---|---|
InnerDataTable | Provides a means for accessing the underlying DataTable object directly. | |
IsClosed | Retrieves a Boolean value indicating whether the DataTableReader is closed. (Overrides DataReader.IsClosed.) | |
ItemCount | Override. Retrieves an integer value specifying the number of data items contained in the current DataTableReader instance. (Overrides DataReader.ItemCount.) | |
Status | Retrieves an integer value representing the status of the data table; however, invariably returns zero. (Overrides DataReader.Status.) |

Methods
Name | Description | |
---|---|---|
Close | Closes the current DataTableReader instance. (Overrides DataReader.Close().) | |
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.) | |
Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
Finalize | Finalizes the current DataReader instance. (Inherited from DataReader.) | |
GetBytes | Reads a stream of bytes into the buffer as an array, starting at a specified offset (Overrides DataReader.GetBytes(Int32, array<Byte[], Int32, Int32).) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetItem(Int32) | Retrieves a data item at a specified index. (Overrides DataReader.GetItem(Int32).) | |
GetItem(String) | Retrieves a data item with a specified name. (Overrides DataReader.GetItem(String).) | |
GetItemMaxLength | Retrieves an integer value specifying the maximum length of the data item at the specified index. (Overrides DataReader.GetItemMaxLength(Int32).) | |
GetItemName | Retrieves the string literal name of the data item at the specified index. (Overrides DataReader.GetItemName(Int32).) | |
GetItemType | Retrieves the data type for a data item at a specified index and with a specified item type format. (Overrides DataReader.GetItemType(Int32, DataItemTypeFormat).) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
IsNullItem | Retrieves a Boolean value indicating whether the data item at the specified index is nulla null reference (Nothing in Visual Basic). (Overrides DataReader.IsNullItem(Int32).) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
NextResult | Tests whether there is another result set and if true advances the AdoDotNetDataTableReader. (Overrides DataReader.NextResult().) | |
Read | Tests whether there is another data record and if true advances the AdoDotNetDataTableReader to the next record. (Overrides DataReader.Read().) | |
Terminate | Terminates the data reader immediately, without necessarily returning all of the data nor setting output parameters. (Inherited from DataReader.) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |

Remarks
It is unlikely that a DDEX Provider will need to override or otherwise modify the behavior of this class; rather, they can simply instantiate it whenever they have an ADO.NET DataTable object in hand and they need to return a DataReader object.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
