以下是 C# 中 String 类的属性 -
| Sr.No | 属性 &说明 |
|---|---|
| 1 | Chars 获取当前String对象中指定位置的Char对象。 |
| 2 | Length 获取当前 String 对象中的字符数。 |
让我们看一个示例 -
现场演示
using System; public class Demo { public static void Main() { string str1 = "h8b9"; string str2 = "abcdef"; Console.WriteLine("Is string1 null or empty? = "+string.IsNullOrEmpty(str1)); Console.WriteLine("Is string2 null or empty? = "+string.IsNullOrEmpty(str2)); bool val = str1 != str2; Console.WriteLine("Is str1 equal to str2? = "+val); for (int i = 0; i < str1.Length; i++) { if (Char.IsLetter(str1[i])) Console.WriteLine(""+str1[i]+" is a letter"); else Console.WriteLine(""+str1[i]+" is a number"); } } }
这将产生以下输出 -
Is string1 null or empty? = False Is string2 null or empty? = False Is str1 equal to str2? = True h is a letter 8 is a number b is a letter 9 is a number
现在让我们看另一个例子 -
现场演示
using System; public class Demo { public static void Main() { string str1 = "hijklm"; string str2 = String.Empty; Console.WriteLine("Is string1 null or whitespace? = "+String.IsNullOrWhiteSpace(str1)); Console.WriteLine("Is string2 null or whitespace? = "+String.IsNullOrWhiteSpace(str2)); Console.WriteLine("String1 length = "+str1.Length); Console.WriteLine("String2 length = "+str1.Length); Console.WriteLine("String length = "+"demo".Length); } }
这将产生以下示例 -
Is string1 null or whitespace? = False Is string2 null or whitespace? = True String1 length = 6 String2 length = 6 String length = 4
