Removing White spaces whithin the string

Sometimes we come across situation where we need to remove the whitespace whithin the string.
So here is the simple code for the same.

Step 1: Markup of the page

<asp:TextBox ID="txtAddress" runat="server" TextMode="MultiLine" Columns="20"
            Width="300px" style="height: 300px"></asp:TextBox>
        <br />
        <asp:Button ID="btnCheckAddress" runat="server" Text="Validate Space"
            onclick="btnCheckAddress_Click" />


Step 2: Code

protected void btnCheckAddress_Click(object sender, EventArgs e)
    {
        txtAddress.Text= txtAddress.Text.Trim();//To clear leading and trailing space
        // Following loop is to remove the whitespace within the string
        while (txtAddress.Text.Contains("  "))/Here Contains method check for 2 continues space
        {
            txtAddress.Text = txtAddress.Text.Replace("  ", " ");//Here Replace method will replace 2 continues space with single space
        }
    }

Output:
