我可以通過屬性名稱設置屬性嗎？

Question

使用galasoft mvvm模板的wpf相當新穎。 我有兩個繼電器命令做同樣的事情，但他們需要設置不同的屬性。

我可以這樣做嗎？

public RelayCommand OpenDestinationCommand { get; private set; } 
public RelayCommand OpenSourceCommand { get; private set; } 

public MainViewModel(IDataService dataService) 
{ 
    OpenSourceCommand = new RelayCommand(() => GetPath(SourcePathPropertyName)); 
    OpenDestinationCommand = new RelayCommand(() => GetPath(DestinationPathPropertyName)); 
} 

private void GetPath(string PropertyName) { 
    //show a dialog, get the path they select 
    string newPath = GetPathFromDialog(); 
    //what should this look like? Is this possible? 
    var Property = GetPropertyByName(PropertyName); 
    Property.Set(newPath); 
}

應該首先使用Google搜索。改編自 http://geekswithblogs.net/shahed/archive/2006/11/19/97548.aspx

private PropertyInfo GetPropertyByName(string propName) 
{ 
    return this.GetType().GetProperty(propName); 
} 

private void GetPath(string PropertyName) { 
    //show a dialog, get the path they select 
    string newPath = GetPathFromDialog(); 
    //what should this look like? Is this possible? 
    var mProp = GetPropertyByName(PropertyName); 
    mPropp.SetValue(this, newPath, null); 
}
