Property name

[Guest]

Hi,

class Resource // This class is autogenerated by Visual Studio.
{
internal static string M001
{
get{ return ResourceManager.GetString("M001"); }
}
}


public Main()
{
/*
Logging a message from resources.
If I hover the mouse over M001 in Visual Studio, the tooltip says
"Looks up a localized message similar to MESSAGE TEXT COMES HERE".
*/
LogMessage( Resource.M001 );
}

public LogMessage( ?SomeType? param )
{
/******
I don't want to get "param" as a string here. Instead, I want to
get the name of the property passed as a parameter to this method. Something
like:
******/

Console.Write( param.(MethodInfo or whatever).Name ); // Prints
"M001".
}


In other words, I want to:

- Pass a property (Resource.M001) to a method directly, as a C# identifier,
as this provides compiler type checking and context help.
- In the called method, I want to get the passed property's name ("M001"),
as this name contains encoded additional information about the string the
property retrieves from resources.

I wonder if the above is possible in C# 2.0.

Thanks

Nope. Sorry.

Passing Resource.M001 to a method results in a pass-by-value,
something being pushed on the stack. Once your method starts running,
there is no longer any record of where that value came from. (Apart
from doing some horrible, painful, stack walking and decompiling
stuff.)

Even if you were to pass it as "ref" (which you can't do with
properties anyway), you still couldn't figure out (easily) from which
type the value (to which you now have a reference) came, and which
property within that type was used to give you the value.

So... sorry. No dice.

Sorry about the name, I meant Bruce here.

Thanks Bruce and Walter. Bruce's answer ("not possible") is what I expected
to get anyway. I wanted to avoid hard-coding M001 etc. prefixes into
resource text, but that's what I ended up with.
