示例1: Main
//引入命名空间
using System;
using System.IO;
public class ViewTextFile
{
public static void Main()
{
String[] args = Environment.GetCommandLineArgs();
String errorOutput = "";
// Make sure that there is at least one command line argument.
if (args.Length <= 1)
errorOutput += "You must include a filename on the command line.\n";
for (int ctr = 1; ctr <= args.GetUpperBound(0); ctr++) {
// Check whether the file exists.
if (! File.Exists(args[ctr])) {
errorOutput += String.Format("'{0}' does not exist.\n", args[ctr]);
}
else {
// Display the contents of the file.
StreamReader sr = new StreamReader(args[ctr]);
String contents = sr.ReadToEnd();
sr.Close();
Console.WriteLine("*****Contents of file '{0}':\n\n",
args[ctr]);
Console.WriteLine(contents);
Console.WriteLine("*****\n");
}
}
// Check for error conditions.
if (! String.IsNullOrEmpty(errorOutput)) {
// Write error information to a file.
Console.SetError(new StreamWriter(@".\ViewTextFile.Err.txt"));
Console.Error.WriteLine(errorOutput);
Console.Error.Close();
// Reacquire the standard error stream.
var standardError = new StreamWriter(Console.OpenStandardError());
standardError.AutoFlush = true;
Console.SetError(standardError);
Console.Error.WriteLine("\nError information written to ViewTextFile.Err.txt");
}
}
}
// If the example is compiled and run with the following command line:
// ViewTextFile file1.txt file2.txt
// and neither file1.txt nor file2.txt exist, it displays the
// following output:
// Error information written to ViewTextFile.Err.txt
// and writes the following text to ViewTextFile.Err.txt:
// 'file1.txt' does not exist.
// 'file2.txt' does not exist.
