C#中的Char.IsControl(String，Int32)方法
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。
语法
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-
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
