在 C# 中檢查兩個 StringCollection 物件是否相等
若要檢查兩個 StringCollection 物件是否相等,程式碼如下 −
示例
using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringCollection strCol1 = new StringCollection(); strCol1.Add("Accessories"); strCol1.Add("Books"); strCol1.Add("Electronics"); Console.WriteLine("StringCollection1 elements..."); foreach (string res in strCol1) { Console.WriteLine(res); } StringCollection strCol2 = new StringCollection(); strCol2.Add("Accessories"); strCol2.Add("Books"); strCol2.Add("Electronics"); Console.WriteLine("StringCollection2 elements..."); foreach (string res in strCol1) { Console.WriteLine(res); } Console.WriteLine("Both the String Collections are equal? = "+strCol1.Equals(strCol2)); } }
輸出
這將產生以下輸出 −
StringCollection1 elements... Accessories Books Electronics StringCollection2 elements... Accessories Books Electronics Both the String Collections are equal? = False
示例
讓我們看另一個示例 −
using System; using System.Collections.Specialized; public class Demo { public static void Main() { StringCollection strCol1 = new StringCollection(); strCol1.Add("Accessories"); strCol1.Add("Books"); strCol1.Add("Electronics"); Console.WriteLine("StringCollection1 elements..."); foreach (string res in strCol1) { Console.WriteLine(res); } StringCollection strCol2 = new StringCollection(); strCol2.Add("Accessories"); strCol2.Add("Books"); strCol2.Add("Electronics"); Console.WriteLine("StringCollection2 elements..."); foreach (string res in strCol1) { Console.WriteLine(res); } Console.WriteLine("Both the String Collections are equal? = "+strCol1.Equals(strCol2)); StringCollection strCol3 = new StringCollection(); strCol3 = strCol2; Console.WriteLine("Is StringCollection3 equal to StringCollection2? = "+strCol3.Equals(strCol2)); } }
輸出
這將產生以下輸出 −
StringCollection1 elements... Accessories Books Electronics StringCollection2 elements... Accessories Books Electronics Both the String Collections are equal? = False Is StringCollection3 equal to StringCollection2? = True
