MMDHelpers.CSharp 1.0.2

MMDHelpers.CSharp

This project is a collection of helpers that i've been using across multiple projects

Feedbacks are always welcome 😄

Some of the code are production ready, and some are just experimentations

Projects and purpose

• [Nuget] MMDHelpers.CSharp - simple helpers, you should avoid those if your application need to be high performance GC is not verified.
• [Nuget] MMDHelpers.CSharp.LDAP - simple abstraction to login on a LDAP service.
• [Nuget] MMDHelpers.CSharp.LocalData - generates a localDB, uses dapper as micro-orm.
• [Nuget] MMDHelpers.CSharp.Performance.Grpc - An example to use Grpc to measure Performance (not ideally, but just enough to get the evident ones)
• MMDHelpers.CSharp.Performance.GrpcClient - A client to control the server.
• [Nuget] MMDHelpers.CSharp.PerformanceChecks - Just shows the GC Collection and workingSet being used.

MMDHelpers.CSharp

WriteToFile

As i mentioned before, there are better solutions like Log4net, Serilog, NLog but for small projects or just to Test this is enough.

        ////An Example on Application
        public static void Write(string filename, params string[] texts)
        {
            if (texts.Length == 0) return;
            lock (sync)
            {
                filename
                    .ToCurrentPath()
                    .WriteToFile(new List<string>(texts.Length) { string.Join("", texts.Select(c => $"{DateTime.Now} - {c} {Environment.NewLine}")) });
            }
        }
        
        ////Usage:
        Write("somefile.log","test 1", "test 2");

AsDataTable

As the Example Above this will be enough when your collection is small around 10-150k. beware it'll have overhead, as internally i'm using reflection to get types.

public void SomeMethodToBulkInsert<T>(IEnumerable<T> somelist )
using (var conn = new SqlConnection("someconn"))
{
    conn.Open();
    var transaction = conn.BeginTransaction();
    using (var bulkCopy = new SqlBulkCopy(conn, SqlBulkCopyOptions.Default, transaction))
    {
        bulkCopy.BatchSize = 500;
        bulkCopy.DestinationTableName = "dbo.someTable";
        try
        {
            SqlBulkCopyColumnMapping someColumn = new SqlBulkCopyColumnMapping("source", "destination");
            
            bulkCopy.ColumnMappings.Add(someColumn);
            
            bulkCopy.WriteToServer(somelist.Select(q => new { q.someColumn }).AsDataTable());
            transaction.Commit();
        }
        catch (Exception ex)
        {
            transaction.Rollback();
        }
    }
}

MMDHelpers.CSharp.PerformanceChecks

If you need high performant tools to analyze your code, i recommend my Book of Reference. there i'm collecting Articles, tools to those scenarios.

    Ruler.StopMeasuring(false);
    Ruler.Show(true);
    Ruler.LogToFile();
