xamarin.ios - Monotouch Dialog在委托中获取元素值

Question

我有一个从动态对象创建的根元素。当我点击一个元素时，我想获取对象 ID：

var section = new Section("","Select a complex and then a property");
var root = new RootElement("Complexes"){section};

foreach(Complex complex in complexes){

    var line = new RootElement(complex.Name);

    foreach(Property property in complex.Properties){

        line.Add(new Section(property.Name,"Select the property to work"){

            new StringElement(property.Description, delegate {

                // NEED HELP HERE!!! here I want to get property.Id

            })
        });
    }
    section.Add(line);
}

this.Root = root;

有什么线索吗？非常感谢。

在局部变量中复制 property.Id 并在委托中使用

var line = new RootElement(complex.Name);

foreach(Property property in complex.Properties){

    var propertyId = property.Id;

    line.Add(new Section(property.Name,"Select the property to work"){

        new StringElement(property.Description, delegate {

            (new UIAlertView("title", "Id - " + propertyId, null, "Ok")).Show();

        })
    });
}
section.Add(line);
