In winform, programmatically place the cursor at the end of the text box and scroll the scroll bar to this position

A more convenient and concise operation is:

 

Textboxmsg. appendtext (datetime. Now. tostring ( " Yyyy-mm-dd hh: mm: Ss. fff " ) +   " : "   + MSG +   " \ R \ n " );

In the past, I wrote another complex method:

Private   Void Txtboxrecivecmd_textchanged ( Object Sender, eventargs E)
{
Txtboxrecivecmd. selectionstart = Txtboxrecivecmd. Text. Length +   10 ; // Set the start position of the selected text to the text length of the text box. If the length of the text is exceeded, it is the end of the text by default.
Txtboxrecivecmd. selectionlength =   0 ; // Set the length of the selected text to 0 (move the cursor to the end of the text)
Txtboxrecivecmd. scrolltocaret (); // Move the scroll bar to the cursor position
}
