上文中while()循环块是需要具体的、额外的<condition> 表达式来控制需要执行的命令语言,而foreach()循环则是类似C/C++的for循环风格来控制的,只是foreach块的打开和关闭指令分别是foreach() 和endforeach(),其定义如下所示: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 foreach(<loop_

Usually, this option was used in order to allow nonstandard code that uses loop variables after the point where, according to the standard, they should have gone out of scope. It was only necessary when you compiled with the /Za option, since without /Za, use of a for loop variable aft...
Assert.IsTrue(bts.All(p=> p ==newValue)); } 输出结果为: Memset with Span.Fill:54ms Memset with for loop:74ms Memset with Array.Fill:3ms Span.Fill的效率相对Array.Fill差距还是有点巨大的,仅是比循环设定值快一些。 接下来看memcpy:
