我需要一些LINQ查询的帮助。LINQ查询 - 从另一个列表中排除一个列表的值
这里是我的代码:
private void ReturnSensitivitiesSearchResults()
{
PatientRecord PMR = new PatientRecord();
// Return the list of sensitivities (Ingredient objects), but do not include any where the "SuitableForSensitivityChecking" is false - as we wouldn't want to include ingredients in the list where
// they can't be screened for sensitivities. - This returns an array of Ingredient[]
var ListOfSensitivities = FDBSystem.Navigation.GetIngredientsByName(txtSearchText.Text + "*", sensitivityType).Where(n => n.SuitableForSensitivityChecking != false);
// Return a list of all of the Sensitivities logged on a PatientRecord (which is a list of Ingredient objects)
var PatientSensitivities = PMR.Sensitivities;
// Populate the drug information into the grid control.
this.dgvSearchResults.DataSource = ListOfSensitivities.ToArray();
}
class PatientRecord
{
public List<Ingredient> Sensitivities = new List<Ingredient>();
}
我需要的是一个LINQ语句返回敏感性的名单,但不包括那些在PatientRecord灵敏度名单的人。
我想要做的是列出所有的敏感性,在datagridview控件....用户然后可以将其中的一个拖放到树视图控件,将其添加到PatientRecord Sensitivities列表中。然后,我想让datagridview刷新敏感信息,减去病人记录中已有的敏感信息,这样就不能将相同的敏感信息添加到树视图两次。
希望你能帮上忙。
