Parsing int from DataRow cell [closed]

Answer 1

If you know that it's an int you should just cast it accordingly, that's the safest and most efficient approach:

int questionId = item.Field("QuestionId");  // similar to (int) item["QuestionId"]

The Field method also supports nullable types, so if it could be null:

int? questionId = item.Field("QuestionId");
if(questionId.HasValue) Console.Write(questionId.Value);

If it's actually a string(why?) you have to cast it to string and use int.Parse:

int questionId = int.Parse(item.Field("QuestionId"));

If you really don't know what it's type is, you can use System.Convert.ToInt32:

int questionId = System.Convert.ToInt32(item["QuestionId"]);
