GetValues Method

SqlDataReader.GetValues Method (Object[])

 

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

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

override GetValues : 
        values:Object[] -> int

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.

For most applications, this 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 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.

The following example demonstrates using a correctly sized array to read all values from the current row in the supplied SqlDataReader. In addition, the sample demonstrates using a fixed-sized array that could be either smaller or larger than the number of available columns.
