如何使用C#中的SetOut方法？

它是System.Console类的方法。请举例说明，谢了

将 Out 属性设置为指定的 TextWriter 对象
newOut
一个 TextWriter 流，它是新的标准输出。
认情况下，Out 属性会设置为标准输出流。

可以使用封装 FileStream 的 StreamWriter 向文件发送输出。例如：

C# 复制代码
Console.WriteLine("Hello World");
FileStream fs1 = new FileStream("Test.txt", FileMode.Create);
// First, save the standard output.
TextWriter tmp = Console.Out;
StreamWriter sw1 = new StreamWriter(fs1);
Console.SetOut(sw1);
Console.WriteLine("Hello file");
Console.SetOut(tmp);
Console.WriteLine("Hello World");
sw1.Close();

public class InsertTabs {
private const int tabSize = 4;
private const string usageText = "Usage: INSERTTABS inputfile.txt outputfile.txt";
public static int Main(string[] args) {
StreamWriter writer = null;

if (args.Length < 2) {
Console.WriteLine(usageText);
return 1;
}

try {
writer = new StreamWriter(args[1]);
Console.SetOut(writer);
Console.SetIn(new StreamReader(args[0]));
}
catch(IOException e) {
TextWriter errorWriter = Console.Error;
errorWriter.WriteLine(e.Message);
errorWriter.WriteLine(usageText);
return 1;
}
string line;
while ((line = Console.ReadLine()) != null) {
string newLine = line.Replace(("").PadRight(tabSize, ' '), "\t");
Console.WriteLine(newLine);
}
writer.Close();
// Recover the standard output stream so that a
// completion message can be displayed.
StreamWriter standardOutput = new StreamWriter(Console.OpenStandardOutput());
standardOutput.AutoFlush = true;
Console.SetOut(standardOutput);
Console.WriteLine("INSERTTABS has completed the processing of {0}.", args[0]);
return 0;
}
}

同问。。。
