web programming in asp.net (Code Snippets - 1)

Here am sharing the two small code snippets which every web programmer should know.

Code – I

Btw, have u think of throwing a file output rather than Response.Write(“Hello”); from the browser. Use the following code for this purpose.

string outputFilePath = Server.MapPath(“Feed.xml”);

Response.ContentType = “text/xml”;

Response.AddHeader(“Content-Disposition”, “attachment;filename=\”" + outputFilePath + “\”");

Response.TransmitFile(outputFilePath);

Response.End();

Code – II

Already you may aware of the JSON format, In order to convert a C# Generic List to JSON string and vice-versa.  Follow the below steps

1) Add reference to System.Web.Extensions in your project.

// Assume that you have a generic list as shown below,

// List<Student> studentList = GetStudentList();

2) Use Serialize method in JavaScriptSerializer class for serializing generic list to JSON string.

// System.Web.Script.Serialization.JavaScriptSerializer studentSerializer =  new System.Web.Script.Serialization.JavaScriptSerializer();

3) Use Serialize method to convert patient list to JSON string.

// string JStr = studentSerializer.Serialize(studentList);

4) Now, the json string can be set to generic list of type patient as shown below,

//   List< Student > nList = new List< Student >();

//  nList = studentSerializer.Deserialize<List< Student > >(JStr);

Happy Coding
