Syntax

'Declaration
Public Overrides Function GetValues ( _
    values As Object() _
) As Integer
'Usage
Dim instance As SqlCeDataReader
Dim values As Object()
Dim returnValue As Integer

returnValue = instance.GetValues(values)

public override int GetValues (
    Object[] values
)

public:
virtual int GetValues (
    array<Object^>^ values
) override

public int GetValues (
    Object[] values
)

public override function GetValues (
    values : Object[]
) : int

Not applicable.

Parameters

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

Return Value

The number of instances of Object in the array.

Exceptions

Exception type Condition

InvalidOperationException

The operation is not valid. The SqlCeDataReader may be positioned after the last row in the result set.

Remarks

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

You can pass an Object array that contains fewer than the number of columns 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 contained in the resulting row.

This method returns DBNull for null database columns.
