例

IsSurrogateメソッドの例を次に示します。

using namespace System;
int main()
{
   
   // - escape params specifying Unicode not implemented in v7.0
   Console::WriteLine( Char::IsSurrogate( 'a' ) ); // Output: "False"
}

using System;

public class IsSurrogateSample {
    public static void Main() {
        string str = "\U00010F00"; // Unicode values between 0x10000 and 0x10FFF are represented by two 16-bit "surrogate" characters

        Console.WriteLine(Char.IsSurrogate('a'));		// Output: "False"
        Console.WriteLine(Char.IsSurrogate(str, 0));	// Output: "True"
    }
}

open System

let str = "\U00010F00" // Unicode values between 0x10000 and 0x10FFF are represented by two 16-bit "surrogate" characters

printfn $"{Char.IsSurrogate 'a'}"       // Output: "False"
printfn $"{Char.IsSurrogate(str, 0)}"   // Output: "True"

Module IsSurrogateSample

    Sub Main()

        ' NOTE: Visual Basic doesn't give us a way to create a 32-bit Unicode 
        ' character composed of two 16-bit surrogate values, so a case where 
        ' IsSurrogate returns True cannot be included in this sample. 

        Console.WriteLine(Char.IsSurrogate("a"c))       ' Output: "False"

    End Sub
