表示标准输入流的 TextReader。

示例
下面的示例演示如何使用 In
属性。
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
注解
默认情况下,此属性设置为标准输入流。 可以使用 方法将此属性设置为另一 SetIn 个流。
对标准输入流执行的读取操作以同步方式执行。 也就是说,它们一直阻止,直到指定的读取操作完成。 即使对 属性返回的对象调用异步方法(如 )也是如此 ReadLineAsync TextReader In 。
