C# non-ref returning property

I have also ran into this statement when I tried to run the code:
"Could not find any resources appropriate for the specified culture or the neutral culture"
I copied the cs and designer files from the old project and changed the name space in both. I then added this existing code to this project. Is there something else I could be doing?

The code looks OK at first glance but something isn't correct.  Can you post how eConnect.GLAccountType  is declared/defined.

I cannot get to the eConnect code but I can show you this:

This is in something called eConnectionTpe.decomplied
  private GLAccountType[] gLAccountTypeField;

        [XmlElement("GLAccountType", Form = XmlSchemaForm.Unqualified)]
        public GLAccountType[] GLAccountType
        {
            get
            {
                return gLAccountTypeField;
            }
            set
            {
                gLAccountTypeField = value;
            }
        }

eConnect is from a third party ?

            dummy dd = new dummy();

            int iSizeBefore = dd.iArray.Length;
            Array.Resize<int>(ref dd.iArray, 2);
            int iSizeAfter = dd.iArray.Length;
            
            iSizeBefore = dd.GLAccountType.Length;
            //Array.Resize<int>(ref dd.GLAccountType, 9);
            dd.ResizeArray(9);

            iSizeAfter = dd.GLAccountType.Length;

            int x = 9;

Select allOpen in new window

    public class dummy
    {
        public int[] iArray = new int[7];

        public int[] GLAccountType
        {
            get
            {
                return iArray;
            }
            set
            {
                iArray = value;
            }
        }

        public void ResizeArray(int iSize)
        {
            Array.Resize<int>(ref iArray, iSize);
        }

    }

Resizing works perfectly when accessing the array directly.  I get the same error as you when attempting to use the property.  Does the third party code have a function to resize the array (or can you just use the variable in the other class directly rather than via the property?

eConnect is an API for Microsoft Dynamics GP. It is a collection of nodes for writing to the GP databases. I have not used it like this. I do the serialization right in the code and do not bother with creating a temporary xml file. I will test out your suggestion and if does not work I will revert to the way I have always done this.

I gave up with this old approach and converted to what I have always used. This code was from 15 years ago.
