C#中的String.Contains()方法用于返回一个值,该值指示在该字符串中是否出现了指定的子字符串。
public bool Contains (string val);
上面的val是要搜索的字符串。
using System; public class Demo { public static void Main(String[] args) { string str1 = "Akon"; string str2 = "Ak"; Console.WriteLine("String 1 = "+str1); Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode()); Console.WriteLine("String 2 = "+str2); Console.WriteLine("HashCode of String 2 = "+str2.GetHashCode()); Console.WriteLine("String 1 is equal to String 2: {0}", str1.Equals(str2)); Console.WriteLine("Does String 1 has String 2 = "+str1.Contains(str2)); } }
输出结果
String 1 = Akon HashCode of String 1 = 416613838 String 2 = Ak HashCode of String 2 = -839927841 String 1 is equal to String 2: False Does String 1 has String 2 = True
using System; public class Demo { public static void Main(String[] args) { string str1 = "Jacob"; string str2 = "John"; Console.WriteLine("String 1 = "+str1); Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode()); Console.WriteLine("String 2 = "+str2); Console.WriteLine("HashCode of String 2 = "+str2.GetHashCode()); bool res = str1.Contains(str2); if (res) Console.WriteLine("Found!"); else Console.WriteLine("未找到!"); } }
输出结果
String 1 = Jacob HashCode of String 1 = -790718923 String 2 = John HashCode of String 2 = -1505962600 未找到!
