I'm not exactly sure what you are looking to do but you can't "flush" a string builder, its not a stream. You can get its contents with toString() or you can create a new empty string builder:

 builder = new StringBuilder();

i have used...

someStringBuilder.Remove(0,someStringBuilder.Length);

or
string theString = someStringBuilder.ToString();
someStringBuilder.Replace(theString,"");

 it will help u...
