2つの日付の間に月を取得するC＃

Question

Row_Inserting()メソッド中にGetMonths()メソッドを呼び出そうとしていますが、エラーが表示されます。また、このメソッドの値をTotal_Payという名前の変数にコピーするにはどうすればよいですか？このことができます

public override bool Row_Inserting(OrderedDictionary rsold, ref OrderedDictionary rsnew) 
{  
    GetMonths(FROM_DATE, TO_DATE); 
    return true; 
} 

public int GetMonths(DateTime FROM_DATE, DateTime TO_DATE) 
{ 
    if (FROM_DATE > TO_DATE) 
    { 
     throw new Exception("Start Date is greater than the End Date"); 
    } 

    int months = ((TO_DATE.Year * 12) + TO_DATE.Month) - ((FROM_DATE.Year * 12) + FROM_DATE.Month); 

    if (TO_DATE.Day >= FROM_DATE.Day) 
    { 
     months++; 
    } 

    return months; 
}

・ホープ..

public override bool Row_Inserting(OrderedDictionary rsold, ref OrderedDictionary rsnew) 
    { 
     int Total_Pay; 
     DateTime FROM_DATE = DateTime.Parse("02-May-2016"); //Replace with date you need 
     DateTime TO_DATE = DateTime.Parse("08-May-2016"); //Replace with date you need 
     Total_Pay = GetMonths(FROM_DATE, TO_DATE); 
     return true; 
    } 

    public int GetMonths(DateTime FROM_DATE, DateTime TO_DATE) 
    { 
     if (FROM_DATE > TO_DATE) 
     { 
      throw new Exception("Start Date is greater than the End Date"); 
     } 
     int months = ((TO_DATE.Year * 12) + TO_DATE.Month) - ((FROM_DATE.Year * 12) + FROM_DATE.Month); 
     if (TO_DATE.Day >= FROM_DATE.Day) 
     { 
      months++; 
     } 
     return months; 
    } 

そして、これと同様の問題Link
