介绍Asp.net使用Session的方法

public static class SessionExtensions

{

   public static void SetObjectAsJson(this ISession session, string key, object value)

  {

    session.SetString(key, JsonConvert.SerializeObject(value));

  }

  public static T GetObjectFromJson<T>(this ISession session, string key)

  {

    var value = session.GetString(key);

    return value == null ? default(T) : JsonConvert.DeserializeObject<T>(value);

  }

}

var myComplexObject = new MyClass();

HttpContext.Session.SetObjectAsJson("Test", myComplexObject);

var myComplexObject = HttpContext.Session.GetObjectFromJson<MyClass>("Test");

// Microsoft SQL Server implementation of IDistributedCache.

// Note that this would require setting up the session state database.

services.AddSqlServerCache(o =>

{

  o.ConnectionString = "Server=.;Database=ASPNET5SessionState;Trusted_Connection=True;";

  o.SchemaName = "dbo";

  o.TableName = "Sessions";

});

// Redis implementation of IDistributedCache.

// This will override any previously registered IDistributedCache service.

services.AddSingleton<IDistributedCache, RedisCache>();
