C# - Effeciently writing code -

i pasting code snippet below. body suggest better , effecient way of writing this. minimum code written , avoid repetition.

private void setcontrolvisibility() {      if (dropdownlist1.selecteditem.text.equals("getassetsbasicbyid") || dropdownlist1.selecteditem.text.equals("getassetdetailsbyids"))     {         label2.text = "(please enter asset ids e.g. 1,2)";         chkexcludemapfunds.visible = false;         chkpublishxml.visible = true;     }     else if (dropdownlist1.selecteditem.text.equals("getassetsbasicbysedols") || dropdownlist1.selecteditem.text.equals("getassetdetailsbysedols"))     {         label2.text = "(please enter sedols e.g. b1yw440,0003496)";         chkexcludemapfunds.visible = false;         chkpublishxml.visible = true;     }     else if (dropdownlist1.selecteditem.text.equals("getinvestmentreportbyids"))     {         label2.text = "(please enter asset ids e.g. 1:100)";         chkexcludemapfunds.visible = true;         chkpublishxml.visible = false;     }     else if (dropdownlist1.selecteditem.text.equals("getinvestmentreportbysedol"))     {         label2.text = "(please enter sedols e.g. b1yw440:100)";         chkexcludemapfunds.visible = true;         chkpublishxml.visible = false;     }  } 

my alternate code:

private void setcontrolvisibility() {     string resulttext;     bool b = false;      switch (dropdownlist1.selecteditem.text)     {         case "getassetsbasicbyid":         case "getassetdetailsbyids":             b = true;             resulttext = "(please enter asset ids e.g. 1,2)";             break;          case "getassetsbasicbysedols":         case "getassetdetailsbysedols":             b = true;             resulttext = "(please enter sedols e.g. b1yw440,0003496)";             break;          case "getinvestmentreportbyids":         resulttext = "(please enter asset ids e.g. 1:100)";             break;          case "getinvestmentreportbysedol":         resulttext = "(please enter sedols e.g. b1yw440:100)";             break;          default: return;     }      chkexcludemapfunds.visible = !b;     chkpublishxml.visible = b;     label2.text = resulttext; }
