如何在C#中创建StringBuilder？

要在C#中创建StringBuilder，代码如下-

示例

using System;
using System.Text;
public class Demo {
   public static void Main(String[] args) {
      StringBuilder strBuilder1 = new StringBuilder("Tim");
      StringBuilder strBuilder2 = new StringBuilder("Tom");
      Console.WriteLine("Is StringBuilder1 equal to StringBuilder2? = "+strBuilder1.Equals(strBuilder2));
   }
}

输出结果

这将产生以下输出-

Is StringBuilder1 equal to StringBuilder2? = False

示例

让我们看另一个例子-

using System;
using System.Text;
public class Demo {
   public static void Main(String[] args) {
      StringBuilder strBuilder1 = new StringBuilder("John");
      StringBuilder strBuilder2 = new StringBuilder("John");
      StringBuilder strBuilder3 = new StringBuilder();
      StringBuilder strBuilder4 = new StringBuilder(5);
      strBuilder2 = strBuilder3;
      Console.WriteLine("Is StringBuilder3 equal to StringBuilder2? = "+strBuilder3.Equals(strBuilder2));
      Console.WriteLine("StringBuider1 capacity = "+strBuilder1.Capacity);
      Console.WriteLine("StringBuider2 capacity = "+strBuilder2.Capacity);
      Console.WriteLine("StringBuider3 capacity = "+strBuilder3.Capacity);
      Console.WriteLine("StringBuider4 capacity = "+strBuilder4.Capacity);
   }
}

输出结果

这将产生以下输出-

Is StringBuilder3 equal to StringBuilder2? = True
StringBuider1 capacity = 16
StringBuider2 capacity = 16
StringBuider3 capacity = 16
StringBuider4 capacity = 5
