Why can't I do this (or can I) ?

[Ian Semmel]

I haven't used interfaces before, but I thought I'd come across a reason
for using them.



Suppose I have :



public interface ILogger

{

void LogLine(string s);

void LogLine(object o);

}



and somewhere else I have :



public abstract class Log : ILogger

{

public void LogLine ( string s ) { . }

public void LogLine ( object o ) { . }

}



So far so good.



Now if later on again I declare :



protected ILogger log;



I can write statements



log.LogLine ( "sss" );



This all compiles OK.

BUT



It appears I can's set a property



public ILogger

{

set { log = value; }

}



What I'm trying to do is use the same code for WindowsForms and Web
code. The logging method is different for both.



I presume I can use abstract classes, but this is what I thought
interfaces were for.

You need a name for your property:

public ILogger Log {
set { log = value; }
}

My error was even dumber than that.

I actually was trying to type in

get { log = value; }

and was wondering why it didn't work.

Well, I can only see the errors in the code that you actually post...
