        <br />
        <asp:FileUpload ID="FileTest" runat="server" />

</form>

C#:

protected void PrintWaterMark(object sender, EventArgs e)
{
    // Create a bitmap object of the Image, Here I am taking image from File Control "FileTest" 
    Bitmap bmp = new Bitmap(FileTest.PostedFile.InputStream);
    Graphics canvas = Graphics.FromImage(bmp);
    try
    {
        Bitmap bmpNew = new Bitmap(bmp.Width, bmp.Height);
        canvas = Graphics.FromImage(bmpNew);
        canvas.DrawImage(bmp, new Rectangle(0, 0,
bmpNew.Width, bmpNew.Height), 0, 0, bmp.Width, bmp.Height,
GraphicsUnit.Pixel);
        bmp = bmpNew;
    }
    catch (Exception ee) // Catch exceptions 
    {
        Response.Write(ee.Message);
    }
    // Here replace "Text" with your text and you also can assign Font Family, Color, Position Of Text etc. 
    canvas.DrawString(this.txtName.Text, new Font("Arial", 50, FontStyle.Italic), new SolidBrush(Color.White), 50, 100);        
    // Save or display the image where you want. 
    bmp.Save(System.Web.HttpContext.Current.Server.MapPath("WaterMarkImages/" + FileTest.FileName));
