Solution

If for example a date entered in MaskedTextBox with value '01 / 01/1991 'and you want to get only 01011991 would be the best way to do so, even serving 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

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

Example of a zip code field:

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

Or:

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

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 */
