I want to select all the text that is with in text box.

我已经用下面的代码试过了:

I've tried this using the code below:

textBoxResults.SelectionStart = 0;

推荐答案

您可以为此使用内置方法.

You can use the built in method for this purpose.

textBoxResults.SelectAll();
textBoxResults.Focus(); //you need to call this to show selection if it doesn't has focus
