memberInfo.GetValue() C#
提问by Boris Callens
How to get an instance's member's values?
如何获取实例成员的值？
With propertyInfos there is a propertyInfo.GetValue(instance, index), but no such thing exists in memberInfo.
使用 propertyInfos 有一个propertyInfo.GetValue(instance, index)，但在 memberInfo 中不存在这样的东西。
I searched the net, but it seems to stop at getting the member's name and type.
我在网上搜索，但它似乎停止获取成员的姓名和类型。

You have to downcast to FieldInfoor PropertyInfo:
你必须向下转型FieldInfo或PropertyInfo：
switch (memberInfo)
{
case FieldInfo fieldInfo:
return fieldInfo.GetValue(obj);
case PropertyInfo propertyInfo:
return propertyInfo.GetValue(obj);
default:
throw new InvalidOperationException();
}
