using System;
using System.Diagnostics; // Need to add this when using "conditional"

public static void methodA()
{
Console.WriteLine("Method A");
}
[Conditional("saygin")] // Basically - do this method only when compiled with /d:saygin
public static void methodB()
{
Console.WriteLine("Method B - has [conditional(saygin)]");
}
public static void methodC()
{
Console.WriteLine("Method C");
}

}
[Conditional("alex")]

}
[Conditional("saygin"),Conditional("alex")]
public static void methodF()
{
Console.WriteLine("Method F - has [conditional(saygin),conditional(alex)]");
}
}

The output

1] Compiling : csc /d:saygin Debugging.cs
>Debugging.exe
Method A
Method B - has [conditional(saygin)]
Method C
Method D
Method F - has [conditional(saygin),conditional(alex)]

2] Compiling : csc Debugging.cs
>Debugging.exe
Method A
Method C
Method D

3] Compiling : csc /d:saygin;alex Debugging.cs
>Debugging.exe
Method A
Method B - has [conditional(saygin)]
Method C
Method D
Method E - has [conditional(alex)]
Method F - has [conditional(saygin),conditional(alex)]

4] Compiling : csc /d:alex Debugging.cs
>Debugging.exe
Method A
Method C
Method D
Method E - has [conditional(alex)]
Method F - has [conditional(saygin),conditional(alex)]
