Can txt content display on TextBox?

Question

Thank you for your help first.

So far, I already can use openfiledialog component to control txt file.

But now, I also want to that the file's content display to textbox

Such as below, Path of file display textbox2, and I want to display txt's content into textbox1.

How can I do?

	private: System::Void button5_Click(System::Object^  sender, System::EventArgs^  e) {
				 
      
      OpenFileDialog^ openFileDialog1 = gcnew OpenFileDialog;

      openFileDialog1->InitialDirectory = "c:\\";
      openFileDialog1->Filter = "All files (*.*)|*.*|Txt Files (*.txt)|*.txt";
      openFileDialog1->FilterIndex = 2;
      openFileDialog1->RestoreDirectory = true;

      if ( openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK )
      {
		 textBox2->Text = openFileDialog1->FileName; 
		
		 
      }
			 }

In addition,

I use project which is windows forms application.

Then your question has nothing to do with textboxes. You know how to display text in a textbox. What you want to know is how to read text from a file.

Note also that if you use a RichTextBox instead of a
TextBox then you can simply use the LoadFile() member
function.
