Error! Failed to read first row

Hello,

In my case authentication level in both DLMS Director and Client Example .Net is same.
'Low with Password'

Below is the code and attached is the log file for reference

public void GetProfileGenerics()
{
//Find profile generics register objects and read them.
foreach (GXDLMSObject it in Client.Objects.GetObjects(ObjectType.ProfileGeneric))
{

//If trace is info.
if (Trace > TraceLevel.Warning)
{
Console.WriteLine("-------- Reading " + it.GetType().Name + " " + it.Name + " " + it.Description);
}
long entriesInUse = Convert.ToInt64(Read(it, 7));
long entries = Convert.ToInt64(Read(it, 8));
//If trace is info.
if (Trace > TraceLevel.Warning)
{
Console.WriteLine("Entries: " + entriesInUse + "/" + entries);
}
//If there are no columns or rows.
if (entriesInUse == 0 || (it as GXDLMSProfileGeneric).CaptureObjects.Count == 0)
{
continue;
}

//All meters are not supporting parameterized read.
if ((Client.NegotiatedConformance & (Gurux.DLMS.Enums.Conformance.ParameterizedAccess | Gurux.DLMS.Enums.Conformance.SelectiveAccess | Gurux.DLMS.Enums.Conformance.Read)) != 0)
{
Read(it, 2);

try
{
//Read first row from Profile Generic.

object[] rows = ReadRowsByEntry(it as GXDLMSProfileGeneric, 1, 1);
//If trace is info.
if (Trace > TraceLevel.Warning)
{
StringBuilder sb = new StringBuilder();
foreach (object[] row in rows)
{
foreach (object cell in row)
{
if (cell is byte[])
{
sb.Append(GXCommon.ToHex((byte[])cell, true));
}
else
{
sb.Append(Convert.ToString(cell));
}
sb.Append(" | ");
}
sb.Append("\r\n");
}
Console.WriteLine(sb.ToString());
}
}
catch (Exception ex)
{
Console.WriteLine("Error! Failed to read first row: " + ex.Message);
//Continue reading.
}
}
//All meters are not supporting parameterized read.
if ((Client.NegotiatedConformance & (Gurux.DLMS.Enums.Conformance.ParameterizedAccess | Gurux.DLMS.Enums.Conformance.SelectiveAccess)) != 0)
{
try
{
//Read last day from Profile Generic.
object[] rows = ReadRowsByRange(it as GXDLMSProfileGeneric, DateTime.Now.Date, DateTime.MaxValue);
//If trace is info.
if (Trace > TraceLevel.Warning)

//Continue reading.
}
}

}
}

Hello,

I am getting values in this as I enable breakpoint
Read(it, 2)

How can I iterate for loop on Read(it, 2) to get all the values ?

Hello,

Using Below code I am able to read and get the values
var obj = Read(it, 2);
object[] arr = obj as object[];

How can I get buffer based on timestamp as start time and end time ?
