Question

I want to fetch float data from sql server database 2008 R2.

In database there are two fields estimated_amount and actual_amount.

At first only estimated-amount filled contains value, and the actual_amount field is containing NULL.

The problem is that when I fetch data and parse the value it shows error:

System.FormatException was unhandled by user code Message=Input
string was not in a correct format. Source=mscorlib

My code is :

CRM_Doctor_RequestObj.Actual_Amount = float.Parse(Convert.ToString(row["Actual_Amount"]));

Please suggest what I can do..

Answer 1

Write less code and avoid translating to string. You will have to deal with the null separately – Depending on what row is, it may support an IsNull/IsDBNull method, so it would be more like:

if(row.IsNull("Actual_Amount"))
   CRM_Doctor_RequestObj.Actual_Amount = null;
else
   CRM_Doctor_RequestObj.Actual_Amount = (float)row["Actual_Amount"];
