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

  1. 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!\" ";
       }

  2. 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';
    }
    
    NoteNote

    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.

  3. 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));
