示例

下面的代码示例演示了 IsLower。

using System;

public class IsLowerSample {
    public static void Main() {
        char ch = 'a';

        Console.WriteLine(Char.IsLower(ch));				// Output: "True"
        Console.WriteLine(Char.IsLower("upperCase", 5));	// Output: "False"
    }
}

open System

let ch = 'a'

printfn $"{Char.IsLower ch}"                    // Output: "True"
printfn $"""{Char.IsLower("upperCase", 5)}"""   // Output: "False"

Module IsLowerSample

    Sub Main()

        Dim ch As Char
        ch = "a"c

        Console.WriteLine(Char.IsLower(ch))                 ' Output: "True"
        Console.WriteLine(Char.IsLower("upperCase", 5))     ' Output: "False"

    End Sub

End Module
