Display(Return) validation message in catch block

Mahesh Reddy

Hi,

In controller codei have used try and catch blocks

coming to my requirement

I have one model in that i have 2 fields named as Name,Code

In formi have entered only Name

after clicking of submitbutton it was throwing error

everything is ok

problem is that instead of displaying a cutsom error message in catch i need to display what type of exception raised in database

Could please kindly any one help me

Note:ifi can fill all the fields at that time it was saving to database properly

In catch block instead of displaying something went wrong display what type of exception we raised.

Code

............

try

{

State state = new State();

state.Name = Name;

state.Code = st.Code;

db.State.Add(state);

db.SaveChanges();

dbContextTransaction.Commit();

}

catch (Exception)

{

dbContextTransaction.Rollback();

return "Something went wrong";

}

Hi Mahesh,

Do cahnges for your catch block as like below :

catch (Exception ex)
{
dbContextTransaction.Rollback();
return ex.GetType().ToString() ;
}

Thank you.

HI.

You can use like this,

try

{

State state = new State();

state.Name = Name;

state.Code = st.Code;

db.State.Add(state);

db.SaveChanges();

dbContextTransaction.Commit();

}

catch (Exception ex)

{

dbContextTransaction.Rollback();

return ex.GetType().ToString();

}

Which will return the exact type of exception like NullReferenceException,FileNotFoundException etc.

To retrieve more detail about exception you can use ex.Message and as well as ex.StackTrace.

Thanks.
