Question

I’m gettign the error: Error 2 Only assignment, call, increment, decrement, and new object expressions can be used as a statement.

Here is the code:

string masterdin = (@"K:\Drams\Cluse\" +"\\"+"Aia_Gn"+"\\"+Environment.UserName+"\\"+textBox1.Text);
        if(Directory.Exists(masterdin))
        {
            MessageBox.Show("This Export set already exists, please rename your Export set");
            textBox1.Clear();

        }
        else(System.IO.Directory.CreateDirectory(masterdin));

The error exists on this line : else(System.IO.Directory.CreateDirectory(masterdin));

Can someone point out how to make this work?

Answer 1

string masterdin = (@"K:\Drams\Cluse\" +"\\"+"Aia_Gn"+"\\"+Environment.UserName+"\\"+textBox1.Text);
        if(Directory.Exists(masterdin))
        {
            MessageBox.Show("This Export set already exists, please rename your Export set");
            textBox1.Clear();

        }
        else 
System.IO.Directory.CreateDirectory(masterdin);

Don’t put parenthesis around the CreateDirectory (the edited version in this post fixes that issue).
