how can i set the text of a textbox to a c++ code

i want to set the text of a textbox to a c++ code on button click.

i've tried using

textBox1.Text 开发者_JAVA百科= "c++ code here";

but it gives errors because the code is in c#.

You need to manually escape characters like ".

TextBox1.Text = "some code here \"test\" hello...";
