Environment Values

[boenz666]

My task is to read the environment variables and their values and show them in a listBox. I don't have any problems with getting the variables, but I'm not able to get their values...

switch (comboBoxRegion.Text)
{
    case "Global":
        aktenv = new GlobalEnv();
        aktGlobal = true;
        break;
    case "User":
        aktenv = new UserEnv();
        aktGlobal = false;
        break;
    FillComboBox();
}
 
private void FillComboBox()
{
    if (aktGlobal)
    {
        foreach (string var in aktenv.EnumGlobalVars())
        {
            listBox1.Items.Add(var);
        }
    }
 
    else
    {
        foreach (string var in aktenv.EnumUserVars())
        {
            listBox1.Items.Add(var);
        }
    }
}

I cannot find any reference to the GlobalEnv or UserEnv objects you construct in your switch online and cannot compile your code.

You should be able to use System.Environment.GetEnvironmentVariables() to get a dictionary of environment variables, then just iterate through the the values collection instead (Also it's bad code to have the loop twice so I reworked it to only have one loop with different parameters if depending on what's needed):

System.Collections.ICollection vars;
if (aktGlobal)
{
    vars = System.Environment.GetEnvironmentVariables(EnvironmentVariableTarget.Machine).Values;
 
}
else
{
    vars = System.Environment.GetEnvironmentVariables(EnvironmentVariableTarget.User).Values;
}   
foreach (string var in vars)
{
    listBox1.Items.Add(var);
}
