Using Reflection to set a Property with a type of List<CustomClass>
提问by dragonjujo
How can I use reflection to create a generic List with a custom class (List<CustomClass>)? I need to be able to add values and use
propertyInfo.SetValue(..., ..., ...)to store it. Would I be better off storing these List<>'s as some other data structure?
如何使用反射创建带有自定义类 (List<CustomClass>) 的通用列表？我需要能够添加值并用于
propertyInfo.SetValue(..., ..., ...)存储它。将这些 List<> 存储为其他数据结构会更好吗？
Edit:
编辑：
I should have specified that the object is more like this, but Marc Gravell's answer works still.
我应该指定对象更像这样，但 Marc Gravell 的答案仍然有效。
class Foo
{
public List<string> Bar { get; set; }
}
采纳答案by Marc Gravell
class Foo
{
public string Bar { get; set; }
}
class Program
{
static void Main()
{
Type type = typeof(Foo); // possibly from a string
IList list = (IList) Activator.CreateInstance(
typeof(List<>).MakeGenericType(type));
object obj = Activator.CreateInstance(type);
type.GetProperty("Bar").SetValue(obj, "abc", null);
list.Add(obj);
}
}

Here's an example of taking the List<> type and turning it into List<string>.
下面是一个将 List<> 类型转换为 List<string> 的示例。
var list = typeof(List<>).MakeGenericType(typeof(string));
var list = typeof(List<>).MakeGenericType(typeof(string));
