RE: Re: svnversion does not output to stdout

Thank you both for looking into this.

The point wasn't really about Powershell. My real problem is that the SvnVersion task from MSBuild Community Tasks cannot pick up the version number. It's written in .NET; I just figured PS might be easier for more people to try, over C#.

But here goes: this is C# code with the same behavior, and this is roughly equivalent to what the MSBuild Community Tasks uses in its SvnVersion task:

//-----begin script----

Process process = new Process();
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.FileName = @"C:\Program Files\TortoiseSVN\bin\svnversion.exe";
process.StartInfo.Arguments = @"--no-newline ""C:/svn/tortoisesvn""";
process.StartInfo.WorkingDirectory = null;
process.Start();
Console.WriteLine("stdout:");
Console.WriteLine(process.StandardOutput.ReadToEnd());
Console.WriteLine("stderr:");
Console.WriteLine(process.StandardError.ReadToEnd());

//-----end script----

On my computer I get the same behavior. And I noticed this same behavior when I worked at a previous company, I just never investigated until now.

As for the examples you both gave:

BladeOfLight16, your example also fails on my system. Changing to SlikSVN works. I ran both normal PS and the ISE, under both normal and Administrator accounts.

steveking's cmd redirect example works. Piping through the "more" command also works. So it seems that something is different about how cmd and .NET work with stdout.

I am running .NET 4.5 and Powershell 3.
