C#中不安全法典有哪些限制? 例如,如果我使用C或C++的话,我是否真的任意点击和算术?
这是“unsafe”背后的想法,即可以核查的种类的“安全”被删除,如果你愿意,可以从一个类型点到另一个类型点,而没有从上射除 yourself,如果你愿意的话,则与C或C++一样。
例如,在C#使用不同点类型:
fixed (Byte* dstBytes = ¤tImage[0])
{
var dstBuffer = (Int64*)dstBytes;
const int blockCount = ImageSizeInBytes / sizeof(Int64);
for (var j = 0; j < blockCount; j++)
{
dstBuffer[j] = srcBuffer[j];
}
}
注 阵列的类型为Byte[

上,并在某个时候与8条 by合。
是的,这是所有可能的。 http://msdn.microsoft.com/en-us/library/a288474(v=VS.71).aspx“rel=“nofollow noreferer”>。 Unsafe Code Tutorial fromMSDN.
凡是说如何使用这种说法的人,都是一种可怕的想法:是,但出于某种原因。 最近,我不得不(首次)利用这一软件,通过第三方的APIC获得网络数据,该软件已退回<代码>。 页: 1
是的,你可以在你喜欢的地方提出一点点。
然而,由于你的方案在虚拟地址空间运行,你只能获得该空间中实际存在的记忆,即你可以不接触任何其他过程,而且你可以获取已经分配的记忆。

《安全法》规定,能够申报几乎任何原始变量(基本类型)的点数;你允许在点之间投放。 点算法基于点级的储存规模,因此,将计算后或计算后加到点子将按大小提高处理面。
