How to convert variable name to string?

Chesnokov Yuriy

class SomeClass
{
public int SomeVariable;
};
string className = typeof(SomeClass).Name; // returns "SomeClass"
// need to obtain in the same way "SomeVariable"

if i understand you correct; What you need to look at is Boxing and Unboxing in C#. MSDN Boxing and Unboxing[^] boxing-and-unboxing-c#/[^]

If you are using .NET 3 or above, you can use an expression tree to accomplish this. Here's an example of retrieving the field -

private static FieldInfo GetFieldInfo<T>(Expression<Func<T>> field)
{
FieldInfo fi = (field.Body as MemberExpression).Member as FieldInfo;
if (fi == null)
throw new ArgumentException("The field parameter should point to a valid field");
return fi;
}

Can't be done in general as: - Values don't have names; - Most objects don't have names (major exception is WinForm Controls, they have a Name property which is heavily used by Visual Designer); - Variables have a name, obviously, inside the source file; the information is not preserved when compilation finishes. That is why Reflector uses mock names for everything that is a local variable. Hoowever data members such as your SomeVariable do have meta-data inside the class, so you can use reflection to enumerate them, or obtain the value of a variable whose name you know at run-time.

is just silly. Less typing is required to do string className = "SomeVariable"; I suggest you describe the real problem you are trying to solve, not a detail along the wrong path you seem to have chosen; and/or read up on reflection. :)

Please use <PRE> tags for code snippets, they preserve indentation, improve readability, and make me actually look at the code.

Use reflection. I.e. PropertyInfo.Name for the variable names.

Are you looking into the classic infoof[^] problem?

It is in the question, given class variable as input convert it to string:

string name = FieldToString(SomeClass.SomeVariable); // name = "SomeVariable"
