reference to external file in streamwriter


I am trying to create a reference to an external file to write to using
stream writer and a value that is created in a for. Basically the value
that a user will create will be the name of the form.

The code below show my dilemma. The line "using (StreamWriter sw = new
StreamWriter(@" c:\{0}.txt",fmt name)) " does not work as the arguement
"fmtname" is not valid in that context. Do I need to use some string
builder routine prior to this to make the sw accept the input value as its

private void btnOK_Click(obj ect sender, System.EventArg s e)


if (int.Parse(tbSt art.Text)>int.P arse(tbEnd.Text ))

MessageBox.Show ("The value in the End box is less than the Start");
double Vend =System.Convert .ToDouble(tbEnd .Text);

double Interval=System .Convert.ToDoub le(tbInterval.T ext);

double Start=System.Co nvert.ToDouble( tbStart.Text);

if ((Vend-Start) %Interval>0 )

MessageBox.Show ("The interval is not a readily divisible into the End

string fmtname=tbName. Text.ToString() ;

string fmtstart=tbStar t.Text.ToString ();

string fmtend=tbEnd.Te xt.ToString();

using (StreamWriter sw = new StreamWriter(@" c:\{0}.txt",fmt name))


sw.WriteLine("P roc format; ");

sw.WriteLine("v alue {0}",fmtname) ;

sw.WriteLine("{ 0} - {1} = '{0} to {1}'",fmtstart, fmtend);

sw.WriteLine("; ");

sw.WriteLine("R un;");

MessageBox.Show (@"File written to c:\{0}.txt",fmt name);

I think the problem is
using (StreamWriter sw = new StreamWriter(@" c:\{0}.txt",fmt name))
try using
using (StreamWriter sw = new StreamWriter("c :\{0}.txt",fmtn ame))
string filename = String.Format(" c:\{0}.txt",fmt name);
using (StreamWriter sw = new StreamWriter(fi lename));
