C# | Char。to pperinvariant(Char)方法

原文:https://www . geeksforgeeks . org/c-sharp-char-toupperinvariantschar-method/

此方法用于使用不变区域性的大小写规则将 Unicode 字符的值转换为其大写等效字符。

语法:

public static char ToUpperInvariant (char c);

这里， c 是要转换的 Unicode 字符。

返回值:如果 c 已经是大写或者不是字母，这个方法返回 c 参数的大写等价物，或者 c 的不变值。

以下程序说明了字符的使用。方法:

例 1:

c sharp . c sharp . c sharp . c sharp

// C# program to demonstrate
// Char.ToUpperInvariant()
// Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {
        // calling get() Method
        get('A');
        get('a');
        get('B');
        get('b');
        get('-');
    }

    // Defining get() method
    public static void get(char c)
    {

        // getting Unicode character
        // using ToUpperInvariant() Method
        char val = Char.ToUpperInvariant(c);

        // display the char value
        Console.WriteLine("The uppercase equivalent"+
                      " of the {0} is {1}", c, val);
    }
}

Output:

The uppercase equivalent of the A is A
The uppercase equivalent of the a is A
The uppercase equivalent of the B is B
The uppercase equivalent of the b is B
The uppercase equivalent of the - is -

例 2:

c sharp . c sharp . c sharp . c sharp

// C# program to demonstrate
// Char.ToUpperInvariant()
// Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {
        // declaring and initializing char variable
        char c = 'a';

        // getting Unicode character
        // using ToUpperInvariant() Method
        char val = Char.ToUpperInvariant(c);

        // display the char value
        Console.WriteLine("The Uppercase equivalent"+
                       " of the {0} is {1}", c, val);
    }
}

Output:

The Uppercase equivalent of the a is A
