How do I make the method shown below to return the name of the property (see comment below)?

public class MyClass
{
private string _MyProperty = "";
public string MyProperty

get { return _MyProperty; }
set { _MyProperty = value; }

Hmmm. Signed up for EE to get the answer to this question... and its only an answer if your property is unique or the first one in the class. That's almost like saying I can tell you the name of anybody called John.
What is required is something that tells the *compiler* to use the name of the property, rather than access the property itself. What that allows is compile-time checking that some name (string) you're going to use IS the name of such-and-such a property.
For example: if I have a typed DataSet that has a column with name "Fred", then I know there is a column in that table that can be accessed by specifying a name index of "Fred" (yes, I know I can access that field by the property). If I could get the name of the property from the property itself, I could access that field using the name index without having to use a literal "Fred" string (which would become invalid if the field name were to be changed to something else.

I want to be able to do GetPropertyName(thing.Property1) to get the string "Property1" and I don't want to have limitations like its the only property on the class.

There are some ways to achieve this, but you have to post your own question.
try with GetProperty():

this.GetType().GetProperty("prop_name")

Hi Jaime,
Thanks for your suggestion, but it still codes a literal string of the property name, "prop_name"
I have posted a new question - and got a solution!
see "How to really get the name of a property or method"
Cheers
