c# - RichTextBox.Select(0,1) configures whole text -

this codesnippet:

  richtextbox1.select(0, 1);   richtextbox1.selectionbackcolor = color.black;   richtextbox1.selectioncolor = color.white; 

after part executed first symbol of text selected, whole code formated.

here's whole methode:

where proccesses list<system.diagnostics.proccess>

and knownprocesses list<proccessdata>

processdata "datawrapper" wrote

    void updatertb1()     {         string text = "";          (int = 0; < processes.count; i++)         {             foreach (processdata pd in knownprocesses)             {                 if (pd.resembles(processes[i]))                 {                     text += pd.tostring();                     break;                 }             }              text += "\n";         }          richtextbox1.text = text;          richtextbox1.select(0, 1);         richtextbox1.selectionbackcolor = color.black;         richtextbox1.selectioncolor = color.white;     }
