Question

I have been trying to create this console application on C#.NET but I get this error message:

Error 1 Expected class, delegate, enum, interface, or struct

I’m new to C#, I did C++ before.

MAIN FILE:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;


public void Main(string[] args)
{
  string repositories = args[0];
  string transaction = args[1];

  var processStartInfo = new ProcessStartInfo
                           {
                             FileName = "svnlook.exe",
                             UseShellExecute = false,
                             CreateNoWindow = true,
                             RedirectStandardOutput = true,
                             RedirectStandardError = true,
                             Arguments = String.Format("log -t \"{0}\" \"{1}\"", transaction, repositories)
                           };

  var p = Process.Start(processStartInfo);
  var s = p.StandardOutput.ReadToEnd();
  p.WaitForExit();

  if (s == string.Empty)
  {
    Console.Error.WriteLine("Message must be provided");
    Environment.Exit(1);
  }

  Environment.Exit(0);
}

Every method in C# must be contained within a class or struct. There’s no way to define free-standing (“top level”) functions in C#.

Try:

public class Program
{
 public static void Main(string[] args)
 {

And an extra } at the end.

If you’re coming from a C++ background, as you indicate, you also shouldn’t assume that struct and class have the same similarities and differences as in C++.
