I'm creating a software, I want to save what I write TextBox in the TextBox itself and after exiting the application and go back to it again, I want what I wrote to be there, I searched many videos and sites including documentation and I only found TextBox saved in Label , but that 's not what I need , I need to write something in textBox or richbox and save it right there in that area after I reopen this writing . Does anyone know how to do this? This in C# visual studio, I'm using visual studio 2019 and trying to do it on WindowsForm, but it seems that C# is abandoned, a simple thing that doesn't have a tutorial in the documentation.
Sorry I don't speak English.
