When passing global reference types to C#, the address is lost.

[Rison-Hub]

1. I defined a global variable to store the reference image. JS code:

   var AllMap = { Image: null};
   ZPV_Read_Image(AllMap,AllPaths.replace("Script", "AUTO Test System/Write/Image_Correction/QCP41/QCP41/Image/QCP41") + "Map.tif");
   function ZPV_Read_Image(objImage, FileName) {
   var FunctionName; 
   FunctionName = "ZPV_Read_Image";
   var sPar = [objImage, FileName]; 
   var oResult; 
   oResult = zpv.RunHalconCode(FunctionName, sPar); 
   objImage.Image = oResult[0];
   zpv.TestImage(objImage.Image);
   }

   The value address of the image obtained from oResult[0] is 0x0000029e400310.

C# Code

public object RunHalconCode(string FunctionName, ScriptObject sPar)
        {
            if (Mod_Variable.V_RegVideo == false)
            {
                var frm_about = new Fm_about();
                frm_about.ShowDialog(frm);
            }
            int length = sPar.PropertyIndices.Count(); 
            System.Object[] objectArray = new System.Object[length];
            for (int i = 0; i < length; i++)
            {
                objectArray[i] = sPar.GetProperty(i); 
            }
            var Rxobj = ZP_Halcon_HdevEngine2.RunHalconScript(frm, PageIndex, EditMain_frm, FunctionName, objectArray);
            object[] obj = (object[])Rxobj;
            return obj;
        }
public void TestImage(object add) 
        { 
            HObject hObject = new HObject();
            hObject = (HObject)add;
        }

add has an address of ‘0x000000000000000’ The address of add should be 0x0000029e400310 in this context.

But when I modify the JavaScript code as follows, everything works correctly. JS Code:

var AllMap = { Image: null};
ZPV_Read_Image(AllMap,AllPaths.replace("Script", "AUTO Test System/Write/Image_Correction/QCP41/QCP41/Image/QCP41") + "Map.tif");
function ZPV_Read_Image(AllMap, FileName) {
    var FunctionName; 
    FunctionName = "ZPV_Read_Image";
    var sPar = [AllMap , FileName]; 
    var oResult; 
    oResult = zpv.RunHalconCode(FunctionName, sPar); 
    AllMap.Image = oResult[0];
    zpv.TestImage(AllMap.Image);
}

When I pass global parameters into a method, shouldn't the method receive parameters that point to the reference addresses of what I passed in？
