GetProviderSpecificValues Method

In This Topic

Gets all column values for the current row. If possible, a provider-specific type is used.

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Function GetProviderSpecificValues( _
   ByVal values() As Object _
) As Integer

public override int GetProviderSpecificValues( 
   object[] values
)

Parameters

values: An array of System.Object into which to copy the column values.

Return Value

The number of instances of System.Object in the array.

Remarks

This method is equivalent to the GetValues method, the only difference is that this method uses a provider-specific type whenever possible.

Example

csharp

static void GetMyValues(SqlConnection myConnection) {
  SqlCommand cmd = new SqlCommand("SELECT * FROM Test.Dept");
  cmd.Connection = myConnection;
  myConnection.Open();
  try
  {
    SqlDataReader reader = cmd.ExecuteReader();
    reader.Read();

    object[] someValues = new object[5];
    int number = reader.GetProviderSpecificValues(someValues);

    for (short i = 0; i < number; i++)
    {
      Console.WriteLine(someValues[i].ToString());
    }

    reader.Close();
  }
  finally
  {
    myConnection.Close();
  }
}

Visual Basic

Shared Sub GetMyValues(ByVal myConnection As SqlConnection)
  Dim cmd As New SqlCommand("SELECT * FROM Test.Dept")
  cmd.Connection = myConnection
  myConnection.Open()
  Try
    Dim reader As SqlDataReader = cmd.ExecuteReader
    reader.Read()
    Dim someValues As Object() = New Object() {}
    Dim number As Integer = reader.GetProviderSpecificValues(someValues)
    For i As Short = 0 To number - 1
      Console.WriteLine(someValues(i).ToString)
    Next i
    reader.Close()
  Finally
    myConnection.Close()
  End Try
End Sub
