System.InvalidOperationException is an exception that is thrown when an operation is performed that is not valid for the current state of an object. This exception is typically thrown when a method call is made on an object that is not in a valid state to perform the operation, or when an attempt is made to modify an object in a way that is not allowed.
This exception is commonly used when working with objects that have a specific state or set of rules that must be followed in order for them to function correctly. For example, if you try to modify a read-only property or call a method that requires a certain object state to be in place, you may receive an InvalidOperationException.
In general, this exception is used to indicate that the current operation cannot be completed due to an invalid state or condition. To resolve this exception, you must first identify the root cause of the problem and then modify your code to ensure that the object is in the correct state before performing the operation.
