OleDbDataReader.GetValues Method

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

Namespace:  System.Data.OleDb
Assembly:  System.Data (in System.Data.dll)

public override int GetValues(
	Object[] values
)

Parameters

values
Type: System.Object[]

An array of Object into which to copy the attribute columns.

Return Value

Type: System.Int32
The number of instances of Object in the array.

Implements

IDataRecord.GetValues(Object[])

For most applications, the GetValues method provides an efficient means for retrieving all columns, instead of retrieving each column individually.

You can pass an Object array that contains fewer than the number of columns that are contained in the resulting row. Only the amount of data the Object array holds is copied to the array. You can also pass an Object array whose length is more than the number of columns that are contained in the resulting row.

This method returns DBNull for null database columns.
