我正在看这个问题,除了一种奇怪的方式来枚举某些东西之外,op也遇到了麻烦,因为枚举器是一个结构.我知道返回或传递一个struct会使用一个副本,因为它是一个值类型:
public MyStruct GetThingButActuallyJustCopyOfIt()
{
return this.myStructField;
}

要么
public void PretendToDoSomething(MyStruct thingy)
{
thingy.desc = "this doesn't work as expected";
}

所以我的问题是如果MyStruct实现IMyInterface(例如IEnumerable),这些类型的方法是否会按预期工作?
public struct MyStruct : IMyInterface { ... }
//will caller be able to modify the property of the returned IMyInterface?
public IMyInterface ActuallyStruct() { return (IMyInterface)this.myStruct; }
//will the interface you pass in get its value changed?
public void SetInterfaceProp(IMyInterface thingy)
{
thingy.desc = "the implementing type is a struct";
}

这是我正在使用的模板:
var smartTemplate = @"
<div>This is the title</div>
<div>model name: {Name}</div>
<div>model description: {Description}</div>
<div>model rating: {Rating}</div>
{ItemList:
<div>{NestedName} has number equal to {Number}</div>
}";

还有我的视图模型:
public class SimpleTestVM
{
public string Name { get; set; }
public string Description { get; set; }
public int Rating { get; set; }
public NestedSimpleVM[] ItemList { get; set; }
}
public class NestedSimpleVM
{
public string NestedName { get; set; }
