通过我的教科书,但是当我尝试将记录添加到数据库时,我仍然遇到捕获内部异常的问题。在我的类中捕获InnerException的正确语法是什么?
db.SaveChanges 正在引发内部考验。这是我的'addReviews.cs'类文件中添加记录的代码:
public void addReview(int restId, int timeID, string dateValue, string describe, int cuisineId, int serviceId, int ambianceId, string memberId)
{
REVIEW addReview = new REVIEW();
addReview.REVIEW_DATE = Convert.ToDateTime(dateValue);
addReview.REVIEW_DATE_SUBMITTED = DateTime.Today;
addReview.REVIEW_DESC = describe;
addReview.TIME_ID = timeID;
addReview.REVIEWER_ID = 1;
addReview.FOOD_ID = cuisineId;
addReview.SERVCE_ID = serviceId;
addReview.AMBIENCE_ID = ambianceId;
addReview.REST_ID = restId;
addReview.PRICE_ID = 1;
//Add record to database
db.AddToREVIEWs(addReview);
db.SaveChanges();
}
提前致谢!
答案 0 :(得分:1)
试试这个:
try
{
db.SaveChanges();
}
catch(ApplicationException exception)
{
// just log and throw out
System.Diagnostics.Debug.WriteLine(
String.Concat(
"EXCEPTION: ",
exception.ToString));
if (exception.InnerException != null)
{
System.Diagnostics.Debug.WriteLine(
String.Concat(
"INNER EXCEPTION: ",
exception.InnerException.ToString));
}
throw;
}
PS:尝试捕获更具体的异常,在您的情况下也值得抓住SqlException
。
