C#中的Char.IsControl(String,Int32)方法用于指示是否将指定字符串中指定位置的字符归类为控制字符。
public static bool IsControl (string str, int index);
在上面,str是一个字符串。index参数是要在str中求值的字符的位置。
现在让我们看一个实现Char.IsControl(String,Int32)方法的示例-
using System; using System.Globalization; public class Demo { public static void Main(){ string val = "hjk9878hj"; Console.WriteLine("String = "+val); UnicodeCategory unicode = Char.GetUnicodeCategory(val, 4); Console.WriteLine("The value at specific index = "+unicode); bool res = Char.IsControl(val, 4); if (res) Console.WriteLine("找到控制字符!"); else Console.WriteLine("Control character isn't there"); } }
输出结果
这将产生以下输出-
String = hjk9878hj The value at specific index = DecimalDigitNumber Control character isn't there
