Acumatica DAC class generator

Hello everyboydy,



today I want to share with anybody mine implementation of DAC class generator.

By default Acumatica provides you with DAC class generator which is pretty good.

But time from the time I had a need to generate DAC class into text field, and then

put it somewhere in my solution, and Acumatica DAC class generator didn't feet to

mine needs. So I decided to create my own DAC class generator. 

This form has simple interface. In the first line you enter Connection string, at second




line you enter table name, press at generate, and receive DAC class.

You can download source code here

Below goes also some C# code which I've comment later:

    public static string FirstCharToUpper(string input)
    {
        if (String.IsNullOrEmpty(input))
            throw new ArgumentException("ARGH!");
        return input.First().ToString().ToUpper() + String.Join("", input.Skip(1));
    }
 
    public static string FirstCharToLower(string input)
    {
        if (String.IsNullOrEmpty(input))
            throw new ArgumentException("ARGH!");
        return input.First().ToString().ToLower() + String.Join("", input.Skip(1));
    }

Method FirstCharToUpper as input takes string and returns capitalized first character.

Method SplitCamelCase takes string like "stringLikeThis" and will make it like "string Like This".

Method GetColumNames reads needed information about columns. 

And of course meat of code is btnGenerate_Click method which creates string which you can than copy/paste in your solution.
