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
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
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
