How to get the value without a mask from a Maskedtextbox?

Question

I’m wearing a MaskedTextBox for formatting documents.

It is working perfectly, but how do I get the value typed in the field without the mask being present?

Answer 1

Solution

If it is for example a date typed in MaskedTextBox with the value '01/01/1991' and you want to catch only 01011991 would be the best way so, inclusive serve this for any type independent of the mask.

Code:

maskedTextBox1.TextMaskFormat = MaskFormat.ExcludePromptAndLiterals; // tira a formatação
label1.Text = maskedTextBox1.Text; //texto não formatado
maskedTextBox1.TextMaskFormat = MaskFormat.IncludePromptAndLiterals; // retorna a formatação

A suggestion would be to use Extensive Methods:

Like: Create a file with this code, just like.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace System.Windows.Forms
{
    public static class Methods
    {
        public static string TextNoFormatting(this MaskedTextBox _mask)
        {
            _mask.TextMaskFormat = MaskFormat.ExcludePromptAndLiterals;
            String retString = _mask.Text;
            _mask.TextMaskFormat = MaskFormat.IncludePromptAndLiterals;
            return retString;
        }
    }
}

Utilizing:

label1.Text = maskedTextBox1.TextNoFormatting();

Note that the coding has become cleaner.

Answer 2

Instead of the text, you can use replace indicating the character to be taken and what will be rewritten in it, in case nothing ("").

Example of a CEP field:

    mtxtbCep.Text.Replace("-","");

Or:

    mtxtbCep.Text.Replace("-",String.Empty);

Answer 3

The solution I know for this type of problem is using Replace or Remove

string data = "22/04/2014";
data = data.Replace("/", string.Empty); /* parâmetros: Caractere antigo e o substituto dele, no caso uma string vazia. */
data = data.Remove(2, 1).Remove(4,1); /* parâmetros: Índice e a quantidade de caracteres que quero remover a partir daquele Índice */
