This might seam like a strange question but....
public string MyProperty
{
get
{
return "MyProperty";
}
}
How can I replace the return statement go it returns the property name without it being hard coded?

from c#6, you can use nameof keyword to obtain the simple (unqualified) string name of a variable, type, or member (learn.microsoft.com/en-us/dotnet/csharp/language-reference/…)Jeeva Subburaj– Jeeva Subburaj2018-09-18 14:42:20 +00:00Commented Sep 18, 2018 at 14:42

I wouldn't recommend doing this in general but here we go:
return MethodBase.GetCurrentMethod().Name.Substring(4);
Using an obfuscator can totally screw this up, by the way.

Well, isn't that what obfuscators are for? :-)

Johannes: Probably ;) But you don't want them to make your code throw an
IndexOutOfRangeException.

thanks :) that worked perfectly. Some further explanation on why I need this: I was given an application that uses about 50 keys from a webconfig file. And my task is to allow the application to work with any number of clients (needing to replicate these 50 keys for each new client). So, I have moved the keys into a separated file and needed to create a class that encapsulates the data access in order to be able to create an array of clients.

You don't need an obfuscator to potentially screw this up. The JIT might also do it for you by inlining.
If you're using .NET, you can also use LINQ to identify this:
public static string GetName<T>(Func<T> expr)
{
var il = expr.Method.GetMethodBody().GetILAsByteArray();
return expr.Target.GetType().Module.ResolveField(BitConverter.ToInt32(il, 2)).Name;
}
I can't claim credit for this solution - this came from here.

dazzler ;-) +1 very interesting approach, never heard of this
from C# 6, you can use nameof attribute to print the name of property or method name.
switch (e.PropertyName)
{
case nameof(YourProperty):
{ break; }
// instead of
case "YourProperty":
{ break; }
}
