Compare(Object, Object) 例外狀況 ArgumentException a和b都不實作IComparable介面。 -或- a和b是不同的型別,而且二者都不能處理與另外一方的比較。 範例 下列程式代碼範例示範如何Compare根據與Comparer相關聯的文化特性傳回不同的值。 C# usingSystem;usingSystem.C

题目要求 在我们深入了解CAS(Compare And Swap)策略以及它是如何在AtomicInteger这样的原子构造器中使用的,首先来看一下这段代码: public class MyApp {...实际上,这一行是会由JIT翻译为优化的指令序列的JVM内部函数。在x86架构中它就是一条CPU指令LOCK XADD,会比CAS循环的性能好很多。...现在考虑一下当我们有较...
Since the default comparer for object is usually a referential comparison, we will not be able to use Assert.Equal<T>() to test whether our actual object’s attributes are equal to our expected object’s attributes.We could override the default equality comparer for our class… however, this...

方法 CompareTo(Object) 在执行区分区域性的比较时不考虑此类字符。 例如,如果以下代码在 .NET Framework 4 或更高版本上运行,则使用软连字符或 U+00AD) 比较“animal”与“ani-mal” (比较指示这两个字符串是等效的。 C# 复制 using System; public class Example { public static void Main() { string...
