Parameters

info SerializationInfo: SerializationInfo object that contains deserialized values.
name String: Name of deserialized parameter to retrieve.

T: Type of parameter to get from SerializationInfo.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type SerializationInfo. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

SerializationInfo do not have a direct way of determining if an item with a specified name exists, so when calling one of the Get(n) functions you will simply get a SerializationException if the parameter does not exist; similarly you will receive this exception if the parameter fails to properly deserialize. This extension method protects against both of these failures and returns a default value if the named parameter does not exist or cannot be deserialized.
