无法将bool隐式转换成int，求大神看看
            String Stime = txttime.Value.Trim();
            String Shedaline = txtheadline.Text.Trim();
            String path = "/Uplode/";
            String SSfaccessory = Saccessory.FileName;

            String savepath = path + Saccessory;
            Saccessory.SaveAs(Server.MapPath(savepath));

            Maticsoft.Model.SSF SSFModel = new Model.SSF();
            SSFModel.SSFID = 0;
            SSFModel.time = Convert.ToDateTime(Stime);
            SSFModel.headline = Shedaline;
            SSFModel.accessory = SSfaccessory;

            Maticsoft.BLL.SSF SSFService=new BLL.SSF();

            int id = SSFService.Add(SSFModel);【就是提示这一句的错误】
            if (id>0)
            {
                Maticsoft.Common.MessageBox.ShowAndRedirect(this.Page, "专项计划信息添加成功", "List.aspx");
            }
            else
            {
                Maticsoft.Common.MessageBox.Show(this.Page, "专项计划信息添加失败");
            }
------解决方案--------------------
int id =Convert.ToInt32( SSFService.Add(SSFModel）);
这样也不行吗？
------解决方案--------------------

int id = 0;

if(SSFService.Add(SSFModel))

{id = 1;}

            if (id>0)

             {

                 Maticsoft.Common.MessageBox.ShowAndRedirect(this.Page, "专项计划信息添加成功", "List.aspx");

             }

             else

             {

                 Maticsoft.Common.MessageBox.Show(this.Page, "专项计划信息添加失败");

             }
