den gleichen Fehler bekommen System.IndexOutOfRangeException: Tabelle 0 der letzten zwei Tage nicht gefunden

Question

Ich versuche, Daten in Gridview von dieser Klasse zu füllen, aber den Fehler zu bekommen kann Tabelle 0 nicht finden. Ich fügte auch das Bild des Fehlers bei .

ist dies der Code in dem Klassennamen "Class1"

    if (!IsPostBack) 
    { 
     bind(); 
    } 
} 

private void bind1() 
{ 

    Class1 ad = new Class1(); 
    //ad.ip1 = ddl_ip.SelectedValue.ToString(); 
    //Literal_GATEWAY_IP.Text = ddl_ip.SelectedItem.Text.ToString(); 
    //Literal_running_IP.Text = ddl_ip.SelectedItem.Text.ToString(); 
    //Literal_running_IP.Text = ddl_ip.SelectedItem.Text.ToString(); 
    DataSet ds = ad.get_rates(); 

    GridView1.DataSource = ds.Tables[0]; 
    GridView1.DataBind(); 
    GridView2.DataSource = ds.Tables[1]; 
    GridView2.DataBind(); 
    GridView3.DataSource = ds.Tables[2]; 
    GridView3.DataBind(); 
} 

Answer 1

der Datensatz prüfen hat 3 Tische.

if(ds.Tables.Count >0) 
{ 
    GridView1.DataSource = ds.Tables[0]; 
    GridView1.DataBind(); 
    GridView2.DataSource = ds.Tables[1]; 
    GridView2.DataBind(); 
    GridView3.DataSource = ds.Tables[2]; 
    GridView3.DataBind(); 
} 

Answer 2

einen Haltepunkt auf

for (int j = 0; j < dt_switch_record.Rows.Count; j ++)

auf der Uhr für den dt_switch_record.Rows.Count den Wert überprüfen

Wenn es 0 ist, dann ist das Problem, das Dataset ds.Tables.Add (dt_running) füllt nicht auf, weil dt_running null ist, ds.Tables [0] wird niemals existieren, wenn von der Abfrage null Zeilen zurückgegeben werden. Überprüfen Sie Ihre Datenbank/Tabellen und Verbindungszeichenfolge.
