I know this code is far from perfect but in my case this was the only
way to do it correctly because im embedding WPF in C#, and when
applying text regulary the Spellcheck does not work correctly
So this is my code:
RichTextBox temphotfix = new RichTextBox();
temphotfix.Font = new Font(temphotfix.Font.Name, 14);
System.Windows.Documents.TextRange range = new System.Windows.Documents.TextRange(omschrijving.Document.ContentStart, omschrijving.Document.ContentEnd);
temphotfix.Text = oms;
string temp = temphotfix.Rtf;
byte[] byteArray = Encoding.ASCII.GetBytes(temp);
MemoryStream stream = new MemoryStream(byteArray);
range.Load(stream, DataFormats.Rtf);
range = null;
temp = null;
byteArray = null;
temphotfix.Dispose();
stream.Dispose();
I stress tested this, and it seems like ever about 5 times the script gets ran, it adds about 1 MB ram.
What am i doing wrong, i litterly made everyting i used null, or desposed them.

Garbage Collection isn't going to happen when you set things tonullor callDispose. It runs when it deems the memory pressure requires it.

The good news is that with 4GB free RAM, you can afford run this about 20,000 times before running out of memory. So see what happens when you run it 1,000,000 times - and if you run out of memory then, you've got a problem.

you can useUsingblock to decorate theMemoryStreamor as well onRichTextBoxthat will help this object gets deallocated as soon as it comes out of scope, instead of callingDispose.
