Question

User-236691393 posted

Hello friends,

I am new to wcf & web services. I am consuming a web service through web application. I have 5 fields ( 4 are regular string values) 5th is array of keyvaluepairs.

I am trying to get all 5 fields info into Datatable.

            DataTable dt = new DataTable();     
           

            foreach (var item in arr)
            {
                MessageData msg = new MessageData();
                msg.CustAcctKey = item.CustAcctKey;
                msg.CustKey = item.CustKey;
                msg.MessageSubType = item.MessageSubType;
                msg.MessageType = item.MessageType;
                msg.MessageElementArray = new Dictionary<string, string>();
                foreach (myService.MessageValue message in item.MessageElementArray)
                {
                    msg.MessageElementArray.Add(message.key, message.value);
                }
               // msg.MessageElementArray = item.MessageElementArray;
               dt.Rows.Add(msg);

              
            }

I get ArgumentUnhandled exception.

you have to define columns in the data table first then add the obj into it.

like

 sample obj = new sample();
            DataTable dt = new DataTable();
            DataColumn dc = new DataColumn("Name");
            dt.Columns.Add(dc);
            obj.name = "Ram";
            dt.Rows.Add(obj);
