輔助方法，不打印任何東西

Question

我創建了一個輔助方法，鑑於這樣的：

@helper DisputeOpenedDays(DateTime createdDate) 
    { 

     TimeSpan difference = DateTime.Now.Subtract(createdDate); 
     string.Format("0", difference.Days); 
} 

，當我使用它，鑑於這樣的

@DisputeOpenedDays(myobj.CreatedAt) 

它不打印任何東西

Answer 1

Try：

string.Format("{0}", difference.Days); 

大括號缺失。

Answer 2

@helper DisputeOpenedDays(DateTime createdDate) 
{ 
TimeSpan difference = DateTime.Now.Subtract(createdDate); 
@string.Format("{0}", difference.Days); 
}
