Programming

GetType() Vs. Is

I wrote two functions and disassembled them using Reflector:

.method private hidebysig static bool CompareWithIs(class ConsoleApplication1.A x) cil managed
{
.maxstack 2
.locals init ([0] bool flag)
L_0000: nop
L_0001: ldarg.0
L_0002: isinst ConsoleApplication1.B
L_0007: ldnull
L_0008: cgt.un
L_000a: stloc.0
L_000b: br.s L_000d
L_000d: ldloc.0
L_000e: ret
}
private static bool CompareWithIs(A x)
{
return (x is B);
}
