Removing Special Characters From a TextBox

How can one remove some special characters from a TextBox?

Assuming there is TextBox on a Windows Form and you have to enter a password , name, address etc.

If you wish that some some special characters such as comma(,), semicolen(;), plus (+) etc. be removed from the TextBox after, for example, you have clicked a button.Here's a little trick:

You enter in the TextBox for example "+Bo=n;d" and click button1.
The method:

private void button1_Click(object sender, System.EventArgs e) {

char[] trim = {'=', '\', ';','.', ':',',','+','*'}; //you can put here your chars
int pos;
while ((pos = this.textBox1.Text.IndexOfAny (trim)) >= 0)
{
this.textBox1.Text = this.textBox1.Text.Remove (pos, 1);
}//while
}

will be invoked andthe result of the new string without chars in string variable "trim" is displayed in the TextBox.
