要在C#中查找StringBuilder的长度，代码如下-
using System;
using System.Text;
public class Demo {
public static void Main(String[] args) {
StringBuilder strBuilder1 = new StringBuilder("Amy");
StringBuilder strBuilder2 = new StringBuilder("Katie");
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("StringBuider1 maximum capacity = "+strBuilder1.MaxCapacity);
Console.WriteLine("StringBuider1 length = "+strBuilder1.Length);
Console.WriteLine("StringBuider2 capacity = "+strBuilder2.Capacity);
Console.WriteLine("StringBuider2 maximum capacity = "+strBuilder2.MaxCapacity);
Console.WriteLine("StringBuider2 length = "+strBuilder2.Length);
Console.WriteLine("StringBuider3 capacity = "+strBuilder3.Capacity);
Console.WriteLine("StringBuider3 maximum capacity = "+strBuilder3.MaxCapacity);
Console.WriteLine("StringBuider3 length = "+strBuilder3.Length);
Console.WriteLine("StringBuider4 capacity = "+strBuilder4.Capacity);
Console.WriteLine("StringBuider4 maximum capacity = "+strBuilder4.MaxCapacity);
Console.WriteLine("StringBuider4 length = "+strBuilder4.Length);
}
}输出结果
这将产生以下输出-
Is StringBuilder3 equal to StringBuilder2? = True StringBuider1 capacity = 16 StringBuider1 maximum capacity = 2147483647 StringBuider1 length = 3 StringBuider2 capacity = 16 StringBuider2 maximum capacity = 2147483647 StringBuider2 length = 0 StringBuider3 capacity = 16 StringBuider3 maximum capacity = 2147483647 StringBuider3 length = 0 StringBuider4 capacity = 5 StringBuider4 maximum capacity = 2147483647 StringBuider4 length = 0
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("hbjhbkjhbm");
StringBuilder strBuilder2 = new StringBuilder("TomHanks");
StringBuilder strBuilder3 = new StringBuilder();
Console.WriteLine("Capacity of StringBuilder1 = "+strBuilder1.Capacity);
Console.WriteLine("Length of StringBuilder1 = "+strBuilder1.Length);
Console.WriteLine("\nCapacity of StringBuilder2 = "+strBuilder2.Capacity);
Console.WriteLine("Length of StringBuilder2 = "+strBuilder2.Length);
Console.WriteLine("\nCapacity of StringBuilder3 = "+strBuilder3.Capacity);
Console.WriteLine("Length of StringBuilder3 = "+strBuilder3.Length);
}
}输出结果
这将产生以下输出-
Capacity of StringBuilder1 = 16 Length of StringBuilder1 = 10 Capacity of StringBuilder2 = 16 Length of StringBuilder2 = 8 Capacity of StringBuilder3 = 16 Length of StringBuilder3 = 0
