在运行时更改属性名称

Question

Can I change the field of a class at runtime in c#? 我可以在运行时在C＃中更改类的字段吗？

for example, if i have the class: 例如，如果我有课：

public class ExampleClass{
    public string Name;
}

can I Change it at runtime, using reflection or other techniques, to change the Name to Name1? 我可以在运行时使用反射或其他技术对其进行更改，以将Name更改为Name1吗？

public class ExampleClass{
    public string Name1;
}

Answer 1

No, you cannot change the actual members of a type at runtime 不，您不能在运行时更改类型的实际成员

Options: 选项：

create a new type on the fly, that looks a lot like ExampleClass , but has different members - and presumably some mapping code between them 快速创建一个新类型，该类型看起来很像ExampleClass ，但是具有不同的成员-大概它们之间有一些映射代码
if the intent is for some kind of runtime binding, consider ICustomTypeDescriptor or IDynamicMetaObjectProvider - which will allow some frameworks to treat it as though it had a Name1 , even though it actually doesn't (note: things like DynamicObject and ExpandoObject include implementations of IDynamicMetaObjectProvider , but you can do it in other ways) 如果意图是用于某种类型的运行时绑定，请考虑使用ICustomTypeDescriptor或IDynamicMetaObjectProvider它将允许某些框架将其视为具有Name1 ，即使实际上没有（注意：诸如DynamicObject和ExpandoObject类的东西都包含IDynamicMetaObjectProvider实现），但您可以通过其他方式进行操作）
use an indexer, ie so that var val = obj["Name1"]; 使用索引器，即var val = obj["Name1"]; returns something meaningful 返回有意义的东西

Answer 2

Have a look at DynamicObject: 看一下DynamicObject：
