How to: Put Quotation Marks in a String (Windows Forms)

Sometimes you might want to place quotation marks (" ") in a string of text. For example:

She said, "You deserve a treat!"

As an alternative, you can also use the Quote field as a constant. For more detailed information, see the Visual Basic topic Print and Display Constants.

To place quotation marks in a string in your code

In Visual Basic, insert two quotation marks in a row as an embedded quotation mark. In Visual C# and Visual C++, insert the escape sequence \" as an embedded quotation mark. For example, to create the preceding string, use the following code.

Private Sub InsertQuote()
   TextBox1.Text = "She said, ""You deserve a treat!"" "
End Sub

private void InsertQuote(){
   textBox1.Text = "She said, \"You deserve a treat!\" ";
}

private:
   void InsertQuote()
   {
      textBox1->Text = "She said, \"You deserve a treat!\" ";
   }

-or-

Insert the ASCII or Unicode character for a quotation mark. In Visual Basic, use the ASCII character (34). In Visual C#, use the Unicode character (\u0022).

Private Sub InsertAscii()
   TextBox1.Text = "She said, " & Chr(34) & "You deserve a treat!" & Chr(34)
End Sub

private void InsertAscii(){
   textBox1.Text = "She said, " + '\u0022' + "You deserve a treat!" + '\u0022';
}

Note
In this example, you cannot use \u0022 because you cannot use a universal character name that designates a character in the basic character set. Otherwise, you produce C3851. For more information, see Compiler Error C3851.

You can also define a constant for the character, and use it where needed.

Const quote As String = """"
TextBox1.Text = "She said, " & quote & "You deserve a treat!" & quote

const string quote = "\"";
textBox1.Text = "She said, " + quote +  "You deserve a treat!"+ quote ;

const String^ quote = "\"";
textBox1->Text = String::Concat("She said, ",
   const_cast<String^>(quote), "You deserve a treat!",
   const_cast<String^>(quote));
