Random Notes and simple code on Developing Web Sites (Applications) in ASP.net using C#<\/p>\n
\n- The information below primarily apply to the web page model of web-development in C#<\/li>\n
- _PageStart.cshtml runs at each page start\/open<\/li>\n
- _AppStart.cshtml runs at the beginning of the application<\/li>\n
- Syntax to use the Layout file: @{Layout = “\/Shared\/Layout.cshtml”;}<\/li>\n
- if you use this – @{Layout = \/Shared\/Layout.cshtml”;} in the _PageStart.cshtml file, you will not need to use it at the top of each file<\/li>\n
- You can use Microsoft Webmatrix, Visual Web Developer, or Visual Studio for web development<\/li>\n
- Webmatrix, includes IIS Express, and also a database workspace where you can create and use compact SQL Server Databases<\/li>\n
- DateTime.Now : will display current date and time<\/li>\n
- You can connect to a database using var db = Database.Open(“db_name”); <\/li>\n
- db = Database.Open(“db_name”); will look for the database in the same workspace; if not found will use the connection parameter as defined in the web.config file to find and connect to database<\/li>\n
- Executing a query: var queryString = “SELECT * FROM Product ORDER BY Name”; db.Query(queryString)<\/li>\n
- Accessing each row from a rowset of data as returned from database:\n
\nforeach(var entry in db.Query((queryString))) {\n @entry.Id, @entry.Name\n}\n<\/pre>\n<\/li>\n - if (IsPost) : will check if a form is submitted by POST or not<\/li>\n
- username = Request.Form[“username”]; Will retrieve username from the Request object [submitted form with control named username]<\/li>\n
- A basic login authentication code can be as follows\n
\n var username = \"\";\n var password = \"\";\n var ErrorMessage = \"\";\n \n \/\/ If this is a POST request, validate and process data\n if (IsPost){\n \n username = Request.Form[\"username\"];\n password = Request.Form[\"password\"];\n \n if (username.IsEmpty() || password.IsEmpty()){\n ErrorMessage = \"You must specify a username and password.\";\n }else{\n \/\/ Login, Navigate back to the homepage and exit\n if (WebSecurity.Login(username, password, false)){\n Response.Redirect(\"~\/\");\n }\n else{\n ErrorMessage = \"Login failed\";\n }\n }\n }\n \n @if (ErrorMessage!=\"\") {\n @ErrorMessage, Please correct the errors and try again.\n }\n\n <\/pre>\n<\/li>\n - Execute an Insert Statement: db.Execute(“INSERT INTO UserProfile (Email) VALUES (@0)”, email);<\/li>\n
- WebSecurity object can be used for the security of your web-site (application) such as user authentication, block a page until a user is authenticated<\/li>\n
- Block user if he is not logged in [can be added at the top of the page to be blocked]\n
\n @{\n if (!WebSecurity.IsAuthenticated) Response.Redirect(\"~\/Login\"); \/\/redirect to login page\n }\n <\/pre>\n<\/li>\n - WebSecurity.InitializeDatabaseConnection(“db_name”, “profile_of_the_users_table”, “UserId”, “Email”, true);<\/li>\n
- WebSecurity.CreateAccount(email, password, false);<\/li>\n<\/ul>\n
