I'm getting this:
private object setReportValues(object report, FormCollection values)
{
PropertyInfo[] properties = report.GetType().GetProperties();
foreach (PropertyInfo property in properties)
{
string val = values.GetValue(property.Name).ToString();
property.SetValue(report, val, null);
}
return report;
}
Exception is on string val = values.GetValue(property.Name).ToString();. Do I have to check for nulls before?

A NullReferenceException exception is thrown when you try to access a member on a type whose value is null . A NullReferenceException exception typically reflects developer error and is thrown in the following scenarios: You've forgotten to instantiate a reference type.
A NullReferenceException happens when you try to access a reference variable that isn't referencing any object. If a reference variable isn't referencing an object, then it'll be treated as null .
You should never throw a NullReferenceException manually. It should only ever be thrown by the framework itself. From the NullReferenceException documentation: Note that applications throw the ArgumentNullException exception rather than the NullReferenceException exception discussed here.

On this line, yes:
string val = values.GetValue(property.Name).ToString()
Simply because the value of that particular property could be null.
