直接舉例

private dynamic FetchDeptList(string orgCode)
{
    return _deptRepo.Read(x => x.OrgCode == orgCode 
               && (User.IsViewAll || User.AreaCodeList.Contains(x.AreaCode))
               && (User.IsViewAll || User.DeptCodeList.Contains(x.DeptCode))
               && x.Enable == true)
}

private dynamic FetchEmpList(string orgCode)
{
    return _empRepo.Read(x => x.OrgCode == orgCode 
               && (User.IsViewAll || User.AreaCodeList.Contains(x.AreaCode))
               && (User.IsViewAll || User.DeptCodeList.Contains(x.DeptCode))
               && x.Enable == true)
}

private dynamic FetchOfficeList(string orgCode)
{
    return _officeRepo.Read(x => x.OrgCode == orgCode 
               && (User.IsViewAll || User.AreaCodeList.Contains(x.AreaCode))
               && (User.IsViewAll || User.DeptCodeList.Contains(x.DeptCode))
               && x.Enable == true)
}

請問以上三個method 分別在不同的cs裡，但條件式又都一模一樣，有什麼方法可以簡化呢?
