The problem I am having in execute sql statements when special characters are entered into the text box.

The method I am trying is to check the string in the textbox. And insert the escape character just before the special character so the sql statement will execute without error.
My code is below:

String stgName = txtUsername.Text;
        String stgNewName = txtUsername.Text + txtUsername.Text;
        for (int i = 0; i < stgName.Length; i++)
            if (stgName[i] == '\'')
                stgNewName.Insert(i + 1, stgName[i].ToString());
                stgNewName.Insert(i, stgName[i].ToString());

            SqlCommand comm = new SqlCommand("SELECT * FROM LoginTable WHERE userName='" + txtUsername.Text + "' AND userPass='" + txtPassword.Text + "'", conn);
