如果我将方法Multiply
定义为:
public static class Experiment
{
public static int Multiply(int a, int b)
{
return a * b;
}
}
那么为什么编译器会发出这个IL:
.method public hidebysig static int32 Multiply(int32 a, int32 b) cil managed
{
.maxstack 2 //why is it not 16?
.locals init (
[0] int32 CS$1$0000) //what is this?
L_0000: nop //why this?
L_0001: ldarg.0
L_0002: ldarg.1
L_0003: mul
L_0004: stloc.0 //why this?
L_0005: br.s L_0007 //why this?
L_0007: ldloc.0 //why this?
L_0008: ret
}
正如您所看到的,它还包含一些对我没有意义的额外操作码,实际上我希望以下IL:
.method public hidebysig static int32 MyMethod(int32 a, int32 b) cil managed
{
.maxstack 16
L_0000: ldarg.0
L_0001: ldarg.1
L_0002: mul
L_0003: ret
}
做同样的事情。
所以问题是,为什么编译器会在IL中发出额外的OpCode? p>
我正在使用调试模式。
