C#检查两个StringBuilder对象是否相等 _C#StringBuilder对象是否相等

StringBuilder.Equals方法用于检查此实例是否等于指定的对象。

语法：公共布尔等于(System.Text.StringBuilder sb); 在此, sb是要与此实例进行比较的对象, 或者为null。返回值：如果此实例和sb具有相等的字符串, Capacity和MaxCapacity值, 则返回true；否则返回true。否则为假。

【C#检查两个StringBuilder对象是否相等】示例1：

//C# program to if a StringBuilder object //is equal to another StringBuilder object using System; using System.Text; class Geeks {//Main Method public static void Main(String[] args) {//Create a StringBuilder object //with a String passed as parameter StringBuilder st1 = new StringBuilder( "lsbin" ); //Checking whether st1 is //equal to itself or not Console.WriteLine(st1.Equals(st1)); } }

输出如下：

True

示例2：

//C# program to if a StringBuilder object //is equal to another StringBuilder object using System; using System.Text; class Geeks {//Main Method public static void Main(String[] args) {//Create a StringBuilder object //with a String passed as parameter StringBuilder st1 = new StringBuilder( "lsbin" ); //Create a StringBuilder object //with a String passed as parameter StringBuilder st2 = new StringBuilder( "GFG" ); //Checking whether st1 is //equal to st2 or not Console.WriteLine(st1.Equals(st2)); //Create a StringBuilder object //with a String passed as parameter StringBuilder st3 = new StringBuilder(); //Assigning st2 to st3 st2 = st3; //Checking whether st3 is //equal to st2 or not Console.WriteLine(st3.Equals(st2)); } }

输出如下：
