C# Variable Name To String

 

This question already has an answer here:

  • Finding the variable name passed to a function 16 answers

    • 哈克方法，你可以通过Expression获得： 

    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" .

    If you've reassigned it, this is not possible. Values don't keep a history of variable names somewhere.

    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.
