我该怎么做？
I would like to create your miniORM (NHibernate is too heavy and requires a separate library). At the moment the problem is that I have to point out a bunch of constants. For example:
我想创建您的 miniORM（NHibernate 太重了，需要一个单独的库）。目前的问题是我必须指出一堆常量。例如：
public const string FieldIdRules = "idRules"
And then to make transactions in relation samonapisannom profiler. I saw that Hibernate does not need to specify the text value (for the ratio of fields). I want to implement the same.
然后在关系 samonapisannom 分析器中进行交易。我看到Hibernate不需要指定文本值（对于字段的比例）。我想实现相同的。

Hacky approach, you can get via Expression:
hacky方法，你可以通过Expression：
string myVariable = string.Empty;
Expression<Func<object>> expression = () => myVariable;
string name = (expression.Body as MemberExpression).Member.Name;

If you can access a variable by name, you already have its name, so type "MyVariable".
如果您可以通过名称访问变量，则您已经有了它的名称，因此键入"MyVariable".
If you've reassigned it, this is not possible. Values don't keep a history of variable names somewhere.
如果您已重新分配它，则这是不可能的。值不会在某处保留变量名称的历史记录。
So in order to handle field to column mappings, I would suggest a Dictionary. Reflection is a possibility, but is needlessly complicated for a simple task like that.
因此，为了处理字段到列的映射，我建议使用Dictionary. 反射是一种可能性，但对于像这样的简单任务来说是不必要的复杂。
