很简单的问题-启动C＃时自动加载文本框

Question

The tittle says it all :) I am creating a program in C# forms. The user can write a text, and save it. What i now want, is to autoload this textfile, witch only can be at one location - At the Directory.GetCurrentDIrectory() + "text.txt" . So how should this be done?

Answer 1

I am assuming that you want to do this when the form is available, in which case I would recommend using the Form Load event . Just open the file, read its contents, and set the Text property to the contents in the form load.

Answer 2

It's quite simple really:

//Autoload
var filePath = Path.Combine(Directory.GetCurrentDirectory(), "text.txt");
if(File.Exists(filePath))
    yourTextBox.Text = File.ReadAllText(filePath);

As Ryan points out, you could do it in the FormLoad event.
