Output all command line parameters

Question

I am working on a console application, that receives a pretty long list of parameters. For debugging purpose I need to print the parameters passed to a an output file. Right now, I am using the following code to concat command line parameters.

static void Main(string[] args)
{
    string Params = string.Empty;
    foreach(string arg in args)
    {
       Params += arg + ",";
    }
}

Is there any better way to accomplish this?

Answer 1

What about

Params = string.Join(",", args);

Your foreach approach is not very performant. Since a string is immutable, that means for each iteration of the loop, the string will get thrown away for garbage collection, and a new string will be generated. In the string.Join case, only one string will be generated.

Inside the loop, to get around the same performance, you will have to use a StringBuilder, but in this case it's really no reason not to use string.Join since the code will be much more readable.

Answer 2

You could use this piece of code

String.Join(", ", Environment.GetCommandLineArgs())
