ADO.NET Data Access Template

Sat, 04 Oct 2008 23:32:59 +0000

Here’s a basic ADO.NET data access template with a SqlCacheDependency. Just wanted to post this for my future reference.

public static DataSet GetData(long itemID)
{
    DataSet ds = new DataSet();
    string cacheKey = Helpers.GetCacheKey(itemID); //Get a cache key unique to this method.

    if (HttpContext.Current.Cache[cacheKey] != null)
    {
        ds = (DataSet)HttpContext.Current.Cache[cacheKey];
    }
    else
    {
        using (SqlConnection sqlConnection = new SqlConnection(WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
        {
            using (SqlCommand sqlCommand = new SqlCommand())
            {
                sqlCommand.Connection = sqlConnection;
                sqlCommand.CommandType = CommandType.StoredProcedure;
                sqlCommand.CommandText = "sp_Items_GetItemByID";
                sqlCommand.Parameters.Add("@itemID", SqlDbType.BigInt).Value = itemID;
                sqlConnection.Open();

                using (SqlDataAdapter da = new SqlDataAdapter(sqlCommand))
                {
                    da.Fill(ds);
                }
            }
        }

        SqlCacheDependency sqlCacheDependency = new System.Web.Caching.SqlCacheDependency(WebConfigurationManager.AppSettings["DatabaseName"], "Items");
        HttpContext.Current.Cache.Insert(cacheKey, ds, sqlCacheDependency, System.Web.Caching.Cache.NoAbsoluteExpiration, System.Web.Caching.Cache.NoSlidingExpiration);
    }

    return ds;
}

Note that I’ve employed most of the recommended best practices like caching, “using” keywords, stored procedures and connection string inside web.config.

C# Coding Standards and Best Programming Practices

Thu, 17 Jan 2008 00:32:19 +0000

I was reading a best practices document created by the DotNetSpider team which covered many aspects of programming in .NET. I was really impressed by it and I think its a very good reference document. So I’ve decided to make a series of posts where I’ll post sections of their document covering a specific topic.

Some cool tips and tricks posted on Dan Wahlin’s blog.

ASP.NET 2.0 is an awesome framework for developing Web applications. If you’ve worked with it for awhile then that’s no secret. It offers some great new features that you can implement with a minimal amount of code. I wanted to start a list of some of the most simple (yet cool) things you could do with it that required little or no C#/VB.NET code. If you have other suggestions add a comment and I’ll update the list if the suggestion is a simple task that can be applied easily.
