C#中的Console.SetOut(TextWriter)方法用于重定向标准输出流。借助此方法,用户可以将StreamWriter指定为输出对象。 Console.SetOut方法将接收类型为TextWriter的对象。可以将StreamWriter传递给Console.SetOut,并将其隐式转换为TextWriter类型。它只是将标准输出流属性设置为其获取的指定TextWriter对象。
用法:
public static System.IO.TextWriter Out { get; } or public static void SetOut (System.IO.TextWriter newOut); or public static void SetOut(TextWriter newOut)
返回值:它将streamWriter返回到指定的TextWriter对象。
异常:
- 当newOut为null时,抛出ArgumentNullException,它不接受它作为有效参数。
- 发生I /O错误时,将引发IOException。
示例1:
// C# code to demonstrate the use
// of Console.SetOut method
using System;
using System.IO;
class GFG {
// Main Method
static void Main()
{
// Creating a text file named "out" in D Drive
using(StreamWriter writer = new StreamWriter("D:\\out.txt"))
{
Console.SetOut(writer);
Result();
}
}
// Method Result
static void Result()
{
// Writing to the file
Console.WriteLine("GeeksforGeeks");
Console.WriteLine("A Computer Science portal for Geeks!");
}
}
编译和执行:
输出:

Console.WriteLine("This is Console.SetOut Method in C#");
Console.WriteLine("Get programming practices at your own pace !");
portal1.Close();
