Asp.net / C#: How to get the right resource from a class lib
Posted on: 08 May 2013
I have a web application written with C#/ASP.NET that use a Class Library to Get, Insert & Update information.
This is application runs with 2 different language: English & French.

Once the user logged in, I can detect his culture (already stored in db) and it displays correctly french/english labels correctly by retrieving the right resource file.

In the Class Library (.dll), I added 2 Resource Files for French & English version to return error message based on the user culture.

So my problem is when I try to update user profile and the culture is french, and in the "Address" field is empty the system keeps returning the english message no matter the user culture


Here's a snapshot from my Class Library (.dll)


    public string Address1
        {
            get { return _Address1; }
            set
            {
                if (string.IsNullOrEmpty(value))
                {
                    // Error! The field « Address » is mandatory!");
                    throw new Exception(Resources.CTenant_Messages.Address1_Missing.ToString());
                }


                else if (value.ToString().Trim().Length > LibNamtek.Public.CConstant.LENGTH_300)
                {
                    // Error! The total length for « Address » exceeds " + LibNamtek.Public.CConstant.LENGTH_300.ToString() + " caracters.");
                    throw new Exception(Resources.CTenant_Messages.Address1_Length.ToString().Replace("[LENGTH]", LibNamtek.Public.CConstant.LENGTH_300.ToString()));
                }
                else
                {
                    _Address1 = value;
                }
            }
        }
