This article is to share with you about the problems in the common code of ERP-based programs and what to do if excessive encapsulation is not convenient for maintenance. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

When designing an ERP program, it is necessary to extract common code into a common type library. This can reduce code duplication and improve code utilization.

However, there must be a limit to everything, and some common code causes excessive encapsulation, which is not conducive to the understanding of the code.

Examples are as follows

Public class ConfigHelper

{

/ Gets whether the specified path is a valid absolute file path. / / /

/ Any path. OK if null or empty.

Static public bool IsValidPath (string path)

{

Regex r = new Regex (@ "^ (([a-zA-Z]:) | (\)) (\ {1} | (\ {1}) [^\] ([^ /: *?" |] *) +) $")

Return r.IsMatch (path)

}

Public static string GetString (string key)

{

Return System.Configuration.ConfigurationManager.AppSettings [key]

}

}

The second method, GetString, I think its encapsulation is unnecessary. The code that calls the .NET Framework has only one line or a simple number of lines, and encapsulating it can cause obstacles to understanding.

Let's take a look at another method, the encapsulation of it should be based on the specific use scenario.

The copy code is as follows:

Public static decimal GetDecimal (string key)

{

Decimal value = default (decimal)

If ((decimal.TryParse (GetString (key), out value)

{

Return value

}

Else

{

Return 0m

}

}

The function of this method is to convert a string to a numeric type and return the default value of 0 if its value is not of numeric type.

Depending on the scenario, this encapsulation may be necessary to reduce a lot of repetitive code.
