Methods

	Name	Description
	Add(KeyValuePair<String, ModelState>)	Adds the specified item to the model-state dictionary.
	Add(String, ModelState)	Adds an element that has the specified key and value to the model-state dictionary.
	AddModelError(String, Exception)	Adds the specified model error to the errors collection for the model-state dictionary that is associated with the specified key.
	AddModelError(String, String)	Adds the specified error message to the errors collection for the model-state dictionary that is associated with the specified key.
	Clear	Removes all items from the model-state dictionary.
	Contains	Determines whether the model-state dictionary contains a specific value.
	ContainsKey	Determines whether the model-state dictionary contains the specified key.
	CopyTo	Copies the elements of the model-state dictionary to an array, starting at a specified index.

	Merge	Copies the values from the specified ModelStateDictionary object into this dictionary, overwriting existing values if keys are the same.
	Remove(KeyValuePair<String, ModelState>)	Removes the first occurrence of the specified object from the model-state dictionary.
	Remove(String)	Removes the element that has the specified key from the model-state dictionary.
