Reading the name of a variable

[Azat]

Hi,
I am wondering if there is a way in C# to get the name of a variable. Let's
say:

int MyName=3;

How can I get a string with the Value "MyName"? Any ideas on that?

Thanks

You can get it by using reflection.

Type aType = Type.GetType("YourClassName");
FieldInfo[] fields = aType.GetFields();

FieldInfo has property Name.

Hi,

This should only work with the variable is a member of a type, it will not
work if the variable is declared inside a method for example.


Also this do not solve the OP's problem he want to know the name of a
particular variable, not to get a list of the fields of a type.


AFAIK, there is no way to know the name of a variable.


cheers,

This would make sense; after all the semantics at runtime shouldn't
depend on irrelevant details of the source, right? I mean, presumably
if you take a program and just change all the (private) variable names,
you will compile to identical IL...

No - the private type/member variable names are still present in the
IL, but not *local* variable names.
