Converting json string to C# object and vice versa

In order to convert a C# generic list to json string and vice versa,

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

//Assume that, you have a generic list as shown below,
List<Patient> patientList = GetPatients();

Use Serialize method in JavaScriptSerializer class for serializing generic list to Json string.

System.Web.Script.Serialization.JavaScriptSerializer serializer =  new System.Web.Script.Serialization.JavaScriptSerializer();

//use Serialize method to convert patient list to json string

string JStr = serializer.Serialize(patientList);

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

List<Patient> nList = new List<Patient>();

nList = serializer.Deserialize<List<Patient> >(JStr);
