Web Resource creation through SDK message

For a web resource creation through SDK, i referred one msdn page click. In this page they read a text file convert them into binary content and then converted into base64 string.

In my case i had HTML on CRM form Fields, so i fetch the field in Plugin and converted its content into binary format and finally into base64 string. the code for which goes as follows

               string JSContent = TileConfiguration.Attributes["livetile_jscontent"].ToString();
                string HTMLContent = TileConfiguration.Attributes["livetile_htmlcontent"].ToString();

                var bytes = Encoding.UTF8.GetBytes(JSContent + HTMLContent);
                var base64 = Convert.ToBase64String(bytes);

                //Set the Web Resource properties
                WebResource wr = new WebResource
                {
                    Content = base64,
                    DisplayName = "Test1",
                    Description ="Sample Test",
                    Name = "livetile_" +"test1",
                    LogicalName = WebResource.EntityLogicalName,

                   //you can specify type for web resource format

Webpage (HTML)	.htm, .html	1
Style Sheet (CSS)	.css	2
Script (JScript)	.js	3
Data (XML)	.xml	4
Image (PNG)	.png	5
Image (JPG)	.jpg	6
Image (GIF)	.gif	7
Silverlight (XAP)	.xap	8
StyleSheet (XSL)	.xsl, .xslt	9
Image (ICO)	.ico	10

                    WebResourceType = new OptionSetValue(1)
                };

                CreateRequest cr = new CreateRequest
                {
                    Target = wr
                };
                //Set the SolutionUniqueName optional parameter so the Web Resources will be
                // created in the context of a specific solution.
                //cr.Parameters.Add("SolutionUniqueName", _ImportWebResourcesSolutionUniqueName);

                CreateResponse cresp = (CreateResponse)service.Execute(cr);

To update the same web resource, You can do it using UpdateRequest, the code for which goes like below

                WebResource wr = new WebResource
                {
                   //Just pass the web resource ID
                    Id = new Guid(TileConfiguration.Attributes["livetile_webresourceid"].ToString()),
                    Content = base64,
                    DisplayName = "Test1",
                    Description = "Sample Test",
                    Name = "livetile_" + "test1",
                    LogicalName = WebResource.EntityLogicalName,
                    WebResourceType = new OptionSetValue(1)
                };

                UpdateRequest up = new UpdateRequest
                {
                    Target = wr
                };

             
                service.Execute(up);

Thanks.
