private GDOperations.GDDoneOperationsClient _gdDoneOperation;
  private ImageOperationsClient proxy = null;
 foreach (var file in _filesCollection)
            {
                clsImageTransactionEntity _clsImageEntity = new clsImageTransactionEntity();
                _clsImageEntity.ImageByte = GetFileData(file.OpenRead());
                _clsImageEntity.ImageExtension = file.Extension;
                _clsImageEntity.ImageName = file.Name;
                _clsImageEntity.ImageType = 2;
                _clsImageEntity.ImagePath = "~/CMSImages/FinalImages/" + lblSelectedBarcode.Content.ToString() + "/" + file.Name;
                _clsImageEntity.JabongBarcode = lblSelectedBarcode.Content.ToString();
 
               
                GDOperations.clsImageTransactionEntity _clsImageGDEntity = new GDOperations.clsImageTransactionEntity();
                _clsImageGDEntity.ImageExtension = file.Extension;
                _clsImageGDEntity.ImageName = file.Name;
                _clsImageGDEntity.ImageType = 2;
                _clsImageGDEntity.ImagePath = "~/CMSImages/FinalImages/" + lblSelectedBarcode.Content.ToString() + "/" + file.Name;
                _clsImageGDEntity.JabongBarcode = lblSelectedBarcode.Content.ToString();
                _clsImageGDEntity.RoleId = roleID;
                _clsImageGDEntity.TaskID = taskID;
                _clsImageGDEntity.UserID = UserId;
                _clsImageGDEntity.SystemIP = systemIP;
                _clsGdAllotment.clsImageTransactionEntity.Add(_clsImageGDEntity);
//----- first method calling-----                
proxy.UploadFinalImageCompleted += (s, e) =>
                {
                    if (e.Error == null)
                    {
                        
                    }     
                };
                proxy.UploadFinalImageAsync(_clsImageEntity);
                countfile = countfile + 1;
                pbUploadFiles.Value = countfile;
                
            }
            _clsGdAllotment.GdID = int.Parse(lblUserID.Content.ToString());
            _clsGdAllotment.JabongBarcode = lblSelectedBarcode.Content.ToString();
            _clsGdAllotment.TaskID = taskID;
//--- after for loop completion calling second method -----
            _gdDoneOperation.InsertGDDoneInformationCompleted += _gdDoneOperation_InsertGDDoneInformationCompleted;
            _gdDoneOperation.InsertGDDoneInformationAsync(_clsGdAllotment);

Solution 1

Call your 2nd method in the completion handler of the first. Ensure your first async callback returns successfully before calling the 2nd method.
