Voorbeelden

In het volgende voorbeeld wordt elk SqlError in de SqlErrorCollection verzameling weergegeven.

public static void ShowSqlException(string connectionString)
{
    string queryString = "EXECUTE NonExistantStoredProcedure";

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand(queryString, connection);
        try
        {
            command.Connection.Open();
            command.ExecuteNonQuery();
        }
        catch (SqlException ex)
        {
            DisplaySqlErrors(ex);
        }
    }
}

private static void DisplaySqlErrors(SqlException exception)
{
    for (int i = 0; i < exception.Errors.Count; i++)
    {
        Console.WriteLine("Index #" + i + "\n" +
            "Error: " + exception.Errors[i].ToString() + "\n");
    }
    Console.ReadLine();
}

Public Sub ShowSqlException(ByVal connectionString As String)
    Dim queryString As String = "EXECUTE NonExistantStoredProcedure"

    Using connection As New SqlConnection(connectionString)
        Dim command As New SqlCommand(queryString, connection)

        Try
            command.Connection.Open()
            command.ExecuteNonQuery()

        Catch ex As SqlException
            DisplaySqlErrors(ex)
        End Try
    End Using
End Sub

Private Sub DisplaySqlErrors(ByVal exception As SqlException)
    Dim i As Integer

    For i = 0 To exception.Errors.Count - 1
        Console.WriteLine("Index #" & i & ControlChars.NewLine & _
            "Error: " & exception.Errors(i).ToString() & ControlChars.NewLine)
    Next i
    Console.ReadLine()
End Sub

Opmerkingen

Deze klasse wordt gemaakt door SqlException exemplaren van de SqlError klasse te verzamelen. SqlErrorCollection bevat altijd ten minste één exemplaar van de SqlError klasse.
