c# - Converting string to DateTime safely -

i have string came database, i´m not sure valid datetime.

first i´m trying validate if it´s null,

then if not null want safely convert datetime because i´m not sure row["a"].tostring valid datetime

output.limitexpirydate = row["a"] == dbnull.value ? datetime.now : "something convert here";

does have idea?

you can utilize datetime.tryparse:

output.limitexpirydate = datetime.now; datetime limitexpirydate; if(row["a"] != dbnull.value && datetime.tryparse(row.field<string>("a"), out limitexpirydate)) output.limitexpirydate = limitexpirydate;

it nullable datetime column utilize field method supports nullable types:

datetime? limitexpirydate = row.field<datetime?>("a"); if(limitexpirydate.hasvalue) output.limitexpirydate = limitexpirydate.value;
