예제

다음 예제에서는 각 SqlError 내에서 SqlErrorCollection 컬렉션입니다.

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
