方法一: string title = "STRING"; bool contains = title.IndexOf("string", StringComparison.OrdinalIgnoreCase) >= 0; 方法二:封装起来 public static bool Contains(this string source, string toCheck, StringComparison comp) { return source.IndexOf(toCheck, comp) >= 0; }...

java中我们经常使用String 的contains方法去判断是不是含有某个元素。觉得这种api使用很方便,见下面代码 longstartime=System.currentTimeMillis();Set<Integer>hashset=newHashSet<>(10000000);for(inti=0;i<10000000;i++){hashset.add(i);}System.out.println(hashset.contains(1));System.out.println(hashset...
textBox1.Text = Test.Contains(new string [] {"1", "2"}).ToString(); //textBox1 因為是比對不同的陣列實體,所以會等於 flase 所以想請問各位前輩,如果要比對List<string [] >內是否有{"1","2"}因該如何處理呢? 麻煩各位解惑,謝謝
