Starting Default Browser with a Local File from a C# WFA app

Question

I've been trying to make an application I'm working on launch my default browser and load a local help file. The code I'm using is: string target = @timers.htm; try { System.Diagnostics.Process.Start(target); } catch ( System.ComponentModel.Win32Exception noBrowser) { if (noBrowser.ErrorCode == -2147467259) MessageBox.Show(noBrowser.Message); } catch (System.Exception other) { MessageBox.Show(other.Message); } This works fine if I use IE or Edge as my default browser but I really want to use Chrome. But with Chrome set as the default browser it launches but gives me a file not found error. I suspect I'm missing something simple here but can't seem to track it down. Can anyone help me with this? Thanks Jerry

Thanks Amit I had tried that and it didn't work but your answer got me to re-test and here's what I found: 1 (doesn't work) string target = @timers.htm; 2 (doesn't work) string target = C:\DATA\Programming\VS2015\Projects\C#_WFA\Timers\Timers\bin\Debug\timers.htm; 3 (works) string target = C:\timers.htm; 4 (doesn't work) string target = C:\DATA\Programming\VS2015\Projects\C#_WFA\timers.htm; 5 (works) string target = C:\DATA\Programming\VS2015\Projects\CS_WFA\timers.htm; The problem shows itself in tries 4 & 5: the # in the path. It doesn't bother IE or Edge but Chrome doesn't like it.
