ASP.NET MVC 增强Convert用法+【分页2】

【分页2】

public dynamic PageQuery() {
int pageIndex = Request.Params["page"] == null ? 1 : int.Parse(Request.Params["page"]);//Request["page"] 需要显示第几页 EasyUI datagrid自传
int pageSize = Request.Params["rows"] == null ? 10 : int.Parse(Request.Params["rows"]);//每页大小 EasyUI datagrid自传
try {
BackUserInfoPageCondition condition = new BackUserInfoPageCondition
{
pageIndex=pageIndex,
pageSize=pageSize,
UserCode = Request.Params["search_UserCode"],
UserName = Request.Params["search_UserName"],
IDNO = Request.Params["search_IDNO"],
Phone = Request.Params["search_Phone"],
DepartId = Request.Params["search_Depart"].Trim().ConvertTo<int>(),//默认-1请选择
DutyId = Request.Params["search_Duty"].Trim().ConvertTo<int>() ,
StatusFlag = Request.Params["search_StatusFlag"].Trim().ConvertTo<short?>(),
DimissionFlag = Request.Params["search_DimissionFlag"].Trim().ConvertTo<short?>(),
DisableFlag = Request.Params["search_DisableFlag"].Trim().ConvertTo<short?>(),
LockFlag = Request.Params["search_LockFlag"].Trim().ConvertTo<short?>()
};
var data = _IBackUserInfoService.PageQuery(condition);//根据条件query查询
var o = new { total = condition.total, rows = data };//EasyUI datagrid需要
return Json(o);
}
catch (Exception e)
{
//写日志
return Content("ERROR");
}
