C＃中的Console.Read()方法

Console.Read()方法用于从标准输入流中读取下一个字符。当用户键入一些输入字符时，此方法基本上会阻止其返回。用户一旦按ENTER键，它将终止。

Syntax: public static int Read ();

Return Value: It returns the next character from the input stream, or a negative one (-1) if there are currently no more characters to be read.

Exception: This method will give IOException if an I/O error occurred.

下面的程序说明了上面讨论的方法的使用：

范例1：

// C# program to illustrate the use
// of Console.Read Method
using System;
  
namespace GFG {
  
class Program {
  
    static void Main(string[] args)
    {
          
        int x;
        Console.WriteLine("Enter your Character to get Decimal number");
  
        // using the method
        x = Console.Read();
        Console.WriteLine(x);
    }
}
}

输出：

范例2：

// C# program to illustrate the use
// of Console.Read Method
using System;
  
namespace GFG {
  
class Program {
  
    static void Main(string[] args)
    {
        // Write to console window.
  
        int x;
        Console.WriteLine("Enter your Character to get Decimal number");
        x = Console.Read();
        Console.WriteLine(x);
  
        // Converting the decimal into character.
        Console.WriteLine(Convert.ToChar(x));
    }
}
}

输出：
