```
private void button1_Click(object sender, EventArgs e)
{
ProcessStartInfo psi = new ProcessStartInfo();
psi.WorkingDirectory = @"C:\Test";
psi.FileName = "n4.TestConsole.exe";
Process.Start(psi);

```
<cfset field = reReplace(field, '^"', '')>
<cfset field = reReplace(field, '"$', '')>
<cfset field = replace(field, '\"', '"', 'ALL')>
