Need insight into what this new error means?

This is a .NET error:

Error Message: String was not recognized as a valid Boolean.
Error Source : mscorlib

This may be a bit cryptic-sounding but that's all I have to show. How to go about retracing what happened... I really need help on this, how can this come up if it didn't appear before, though the application was the same. thanks

This error occurs when using bool.Parse() and the input into the method is not convertible to a boolean value of true/false.

For instance:

string testBool = "true";
bool validBool = bool.Parse(testBool);
// this passes fine

testBool = "asdf";
validBool = bool.Parse(testBool);
// Exception: String was not recognized as a valid Boolean.

If you're using .NET 4.0 or higher, you can use bool.TryParse() instead; it will not throw the exception if it receives invalid input. Otherwise, wrap the statement in a try / catch to consume it.
