檢測從ViewModel中點擊了哪個按鈕WPF

Question

我的WPF-App的主窗口上有很多按鈕。 這些按鈕的命令應該具有相同的實現/功能，但取決於按下哪個按鈕，函數訪問的文件/路徑發生了變化。 如何在不使用按鈕點擊事件處理程序（Windows窗體）的情況下檢測從ViewModel單擊哪個按鈕？

這裏是類RelayCommand執行：

public class RelayCommand : ICommand 
{ 

    readonly Func<Boolean> _canExecute; 
    readonly Action _execute; 


    public RelayCommand(Action execute) 
     : this(execute, null) 
    { 
    } 

    public RelayCommand(Action execute, Func<Boolean> canExecute) 
    { 
     if (execute == null) 
      throw new ArgumentNullException("execute"); 
     _execute = execute; 
     _canExecute = canExecute; 
    } 


    public event EventHandler CanExecuteChanged 
    { 
     add 
     { 

      if (_canExecute != null) 
       CommandManager.RequerySuggested += value; 
     } 

     remove 
     { 

      if (_canExecute != null) 
       CommandManager.RequerySuggested -= value; 
     } 
    } 


    public Boolean CanExecute(Object parameter) 
    { 
     return _canExecute == null ? true : _canExecute(); 
    } 

    public void Execute(Object parameter) 
    { 
     _execute(); 
    } 
} 

下面是命令的視圖模型代碼：

void DoThisWorkExecute() 
    { 
     // if Button1 is clicked...do this 

     // if Button2 is clicked...do this 
    } 

    bool CanDoThisWorkExecute() 
    { 
     return true; 
    } 

    public ICommand ButtonCommand { get { return new RelayCommand(DoThisWorkExecute, CanDoThisWorkExecute); } }
