I just ran into an irritating little problem with using TryParse when assigning to nullable object. The following is the code I was using to assign a value from a ASP.NET dropdown list to a nullable Int32 variable:
If Int32.TryParse(ddlExample.SelectedValue, testobj.TestNullableInt32 )Then testobj.TestDescription = ddlExample.SelectedItem.Text End If
Apparently, TryParse actually attempts to access the value of the object to which it attempts to assign the parsed value which can cause an InvalidOperationException when it attempts to retrieve the value of the nullable object. So make sure to assign the parsed value to a regular type before assigning it to a nullable object. Oh yeah, I know it’s VB.NET code, but I do what the client wants. ![]()

If there has ever been any doubt that man is an irony making animal, then this should dispel it:
It’s amazing that people are so terrified about being offended that they run for cover the moment a single one of their convictions is challenged. Just makes me smile.
