What the hell is that?
Overview In my current development I’m using Dapper, a light ORM to access the database. Using Dapper is really easy and provides super-fast performance. Here’s an example of use:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 public async Task<List<T>> GetSomeDataAsync<T>( DateTime startDate, DateTime endDate, CancellationTokenSource sourceToken = null) { if (sourceToken == null) sourceToken = new CancellationTokenSource(); using (var con = CreateConnection()) { var sql = @"SELECT (your field list) FROM (your table/view/function))( @StartDate, @EndDate)"; var command = CreateCommand(sql, new { @StartDate = startDate, @EndDate = endDate }, cancellationToken: sourceToken.
Overview When executing some long-running server side processes on a SQL Server (Stored procedures or functions) would be nice to get progress messages, and why not, a percent value in order to show a progress bar in our application.
In the past I’ve used different techniques to archive this, from SQL Assemblies for calling a SignalR server, to execute xp_cmdshell, and so many other esoteric ways.
None of that solved the problem in an elegant way, but well, it worked… more or less…
Overview Recently I had to read some data from different OLAP cubes and show this information in our application. This could be accomplished using ADOMD.NET client library, which is the multidimensional equivalent to the ADO.NET libraries.
This library provides a set of classes (Connections, Commands and Readers) that allow developers to connect, query and get data from these multidimensional sources in the same way the classical ADO.NET library does.
Maybe the easiest way to read data is using the class AdomdDataReader.
Overview In these times of APIs-everywhere, it may sound like an anachronism the use SFTP to connect to a remote server and get a list of files for exchanging information, but in the financial world (sadly) it’s more common than you think.
In my current project I’ve to connect to a remote server via Secure File Transfer Protocol (aka SFTP) using a user name, a RSA private key and a phassphrase.
Quick note How to remove diacritics (accents) from a C# string?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 public static string RemoveDiacritics(this string input) { var stFormD = input.Normalize(NormalizationForm.FormD); var len = stFormD.Length; var sb = new StringBuilder(); for (int i = 0; i < len; i++) { var uc = System.Globalization.CharUnicodeInfo.GetUnicodeCategory(stFormD[i]); if (uc != System.Globalization.UnicodeCategory.NonSpacingMark) { sb.Append(stFormD[i]); } } return (sb.ToString().Normalize(NormalizationForm.FormC)); } Bonus track How to remove in TSQL (Microsoft SQL Server)
