DataTableReader Class (System.Data) | Microsoft Learn

Close()

Closes the current DataTableReader.

CloseAsync()

Asynchronously closes the DbDataReader object.

(Inherited from DbDataReader) CreateObjRef(Type)

Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.

(Inherited from MarshalByRefObject) Dispose()

Releases all resources used by the current instance of the DbDataReader class.

(Inherited from DbDataReader) Dispose(Boolean)

Releases the unmanaged resources used by the DbDataReader and optionally releases the managed resources.

(Inherited from DbDataReader) DisposeAsync()

Asynchronously releases all resources used by the current instance of the DbDataReader class.

(Inherited from DbDataReader) Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object) GetBoolean(Int32)

Gets the value of the specified column as a Boolean.

GetByte(Int32)

Gets the value of the specified column as a byte.

GetBytes(Int32, Int64, Byte[], Int32, Int32)

Reads a stream of bytes starting at the specified column offset into the buffer as an array starting at the specified buffer offset.

GetChar(Int32)

Gets the value of the specified column as a character.

GetChars(Int32, Int64, Char[], Int32, Int32)

Returns the value of the specified column as a character array.

GetColumnSchemaAsync(CancellationToken)

This is the asynchronous version of GetColumnSchema(DbDataReader). Providers should override with an appropriate implementation. The cancellationToken can optionally be honored. The default implementation invokes the synchronous GetColumnSchema(DbDataReader) call and returns a completed task. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by GetColumnSchema(DbDataReader) will be communicated via the returned Task Exception property.

(Inherited from DbDataReader) GetData(Int32)

Gets the Type that is the data type of the object.

GetFieldValue<T>(Int32)

Gets the value of the specified column as the requested type.

Gets the value of the specified column as a single-precision floating point number.

GetGuid(Int32)

Gets the value of the specified column as a globally-unique identifier (GUID).

GetHashCode()

Serves as the default hash function.

(Inherited from Object) GetInt16(Int32)

Gets the value of the specified column as a 16-bit signed integer.

GetInt32(Int32)

Gets the value of the specified column as a 32-bit signed integer.

GetInt64(Int32)

Gets the value of the specified column as a 64-bit signed integer.

GetLifetimeService()

Obsolete.

Retrieves the current lifetime service object that controls the lifetime policy for this instance.

GetProviderSpecificValues(Object[])

Fills the supplied array with provider-specific type information for all the columns in the DataTableReader.

GetSchemaTable()

Returns a DataTable that describes the column metadata of the DataTableReader.

GetSchemaTableAsync(CancellationToken)

This is the asynchronous version of GetSchemaTable(). Providers should override with an appropriate implementation. The cancellationToken can optionally be honored. The default implementation invokes the synchronous GetSchemaTable() call and returns a completed task. The default implementation will return a cancelled task if passed an already cancelled cancellationToken. Exceptions thrown by GetSchemaTable() will be communicated via the returned Task Exception property.

(Inherited from DbDataReader) GetStream(Int32)

Gets a stream to retrieve data from the specified column.

(Inherited from DbDataReader) GetString(Int32)

Gets the value of the specified column as a string.

GetTextReader(Int32)

Gets a text reader to retrieve data from the column.

Gets the Type of the current instance.

(Inherited from Object) GetValue(Int32)

Gets the value of the specified column in its native format.

GetValues(Object[])

Populates an array of objects with the column values of the current row.

InitializeLifetimeService()

Obsolete.

Obtains a lifetime service object to control the lifetime policy for this instance.

(Inherited from MarshalByRefObject) IsDBNull(Int32)
