c# - How to name excel sheets using interop -

i made sheets in excel file. made lot @ same time code:

newsheet2 = (microsoft.office.interop.excel._worksheet)newworkbook_first.sheets.add(type.missing,type.missing,5,type.missing); 

...but don't know how name them individually. thought had way:

newsheet2[2].name = "hello" 

but gave error. how can this?

        private static microsoft.office.interop.excel.applicationclass appexcel;         private static workbook newworkbook_first = null;         private static _worksheet newsheet2 = null;   public void excel_create(string path)         {             try             {                 appexcel = new microsoft.office.interop.excel.applicationclass();                 appexcel.visible = true;                 newworkbook_first = appexcel.workbooks.add(1);                 newsheet2 = (microsoft.office.interop.excel._worksheet)newworkbook_first.sheets.add(type.missing,type.missing,5,type.missing);                 //how name sheets now?              }             catch (exception e)             {                 console.write("error");             }                         {             }         } 

you close, use 'name', not 'name':

application.activesheet.name="myname";
