看看这个解决方案： http://stackoverflow.com/questions/21675067/convert-text-to-image [ ^ ]

创建httphandler（如image.ashx）并使用类似这样的代码：

Take a look at this solution: http://stackoverflow.com/questions/21675067/convert-text-to-image[^]

Create httphandler (like image.ashx) and use something like this code:

public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "image/png";

        var text = context.Request.Params["text"];
        if (text == null) text = string.Empty;
        var image = CreateBitmapImage(text);

        image.Save(context.Response.OutputStream, ImageFormat.Png);
    }

页面布局：

page layout:

<asp:TextBox runat="server" ID="MyTextBox"></asp:TextBox>
   <asp:Button runat="server" OnClick="RenderImageButtonClicked" Text="Change text"/>
   <asp:Image runat="server" ID="MyTextImage" />

页面事件：

page event:

protected void RenderImageButtonClicked(object sender, EventArgs e)
    {
        MyTextImage.ImageUrl = "CreateImageText.ashx?text=" + HttpContext.Current.Server.UrlEncode(MyTextBox.Text);
    }
