检查Unicode字符是否为小写字母，代码如下 −
示例
using System;
public class Demo {
public static void Main() {
bool res;
char val = 'K';
Console.WriteLine("Value = "+val);
res = Char.IsLower(val);
Console.WriteLine("Is the value a lowercase letter? = "+res);
}
}
输出
这将产生以下输出 −
Value = K Is the value a lowercase letter? = False
示例
让我们看另一个例子 −
using System;
public class Demo {
public static void Main() {
bool res;
char val = 'd';
Console.WriteLine("Value = "+val);
res = Char.IsLower(val);
Console.WriteLine("Is the value a lowercase letter? = "+res);
}
}
输出
这将产生以下输出 −
Value = d Is the value a lowercase letter? = True
