Getting Environment Variables at Runtime

[nehamalik]

Hi All!

I'm building a logging application and I need to get the local variable names and values at runtime for the same. Could anyone please help me on this? :( Can I get them off Stacktrace?

Thanks

Could you post some code? Do explain further too...

Do you mean local variables as %temp%, %systemroot% and %user%?

In the cmd when you type 'set' you will get all the local variables. use this with system.process and extract the data like so:

        public string GetLV()
        {
            System.Diagnostics.Process GetLVP = new System.Diagnostics.Process();
            GetLVP.StartInfo.FileName = "cmd.exe";
            GetLVP.StartInfo.Arguments = "/c set";
            GetLVP.StartInfo.UseShellExecute = false;
            GetLVP.StartInfo.RedirectStandardOutput = true;
            GetLVP.StartInfo.RedirectStandardError = true;
            GetLVP.StartInfo.CreateNoWindow = true;
            GetLVP.Start();
            string Raw LV = GetLVP.StandardOutput.ReadToEnd(); // asynch, thats why we need a waitforexit.
            GetLVP.WaitForExit();
        }

now you have to process whatever you are looking for to use with some regex or an IndexOf

There most certainly is an easier method though.

The easier way for this is to use ' getenvironment variable' as you haven't stated what language :) I have given c# and vb although the command for retrieving is the same anyway , just replace ' ALLUSERSPROFILE ' with the name of the variable

VB -

   MsgBox(Environment.GetEnvironmentVariable("ALLUSERSPROFILE"))

C#

 MessageBox.Show(Environment.GetEnvironmentVariable("ALLUSERSPROFILE"));

As an alternative that can be used for other running processes too:
[code=c#]
private string CurrentProcessE nvironmentVarri ables()
{
System.Diagnost ics.Process ps = System.Diagnost ics.Process.Get CurrentProcess( ); ;
System.Collecti ons.Specialized .StringDictiona ry sd = ps.StartInfo.En vironmentVariab les;
StringBuilder list = new StringBuilder() ;
foreach (string key in sd.Keys)
{
list.AppendForm at("{0}={1}\r\n ", key, sd[key]);
}
//MessageBox.Show (list.ToString( ));
return list.ToString() ;
}
[/code]
