範例

下列範例說明 屬性的使用 In 。

using namespace System;
using namespace System::IO;
int main()
{
   TextReader^ tIn = Console::In;
   TextWriter^ tOut = Console::Out;
   tOut->WriteLine( "Hola Mundo!" );
   tOut->Write( "What is your name: " );
   String^ name = tIn->ReadLine();
   tOut->WriteLine( "Buenos Dias, {0}!", name );
}

using System;
using System.IO;

class InTest {
    public static void Main() {

        TextReader tIn = Console.In;
        TextWriter tOut = Console.Out;

        tOut.WriteLine("Hola Mundo!");
        tOut.Write("What is your name: ");
        String name = tIn.ReadLine();

        tOut.WriteLine("Buenos Dias, {0}!", name);
    }
}

open System

let tIn = Console.In
let tOut = Console.Out

tOut.WriteLine "Hola Mundo!"
tOut.Write "What is your name: "
let name = tIn.ReadLine()

tOut.WriteLine $"Buenos Dias, {name}!"

Imports System.IO

Class InTest
    
    Public Shared Sub Main()
        Dim tIn As TextReader = Console.In
        Dim tOut As TextWriter = Console.Out
        
        
        tOut.WriteLine("Hola Mundo!")
        tOut.Write("What is your name: ")
        Dim name As [String] = tIn.ReadLine()
        
        tOut.WriteLine("Buenos Dias, {0}!", name)
    End Sub
End Class

備註

此屬性預設會設定為標準輸入資料流程。 這個屬性可以使用 方法設定為另一個資料流程 SetIn 。

標準輸入資料流程上的讀取作業會同步執行。 也就是說，它們會封鎖直到指定的讀取作業完成為止。 即使屬性所 In 傳回的物件上 TextReader 呼叫非同步方法，例如 ReadLineAsync ，也是如此。
