Methods

	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The XmlRootAttribute belongs to a family of attributes that controls how the XmlSerializer serializes or deserializes an object.

You can apply the XmlRootAttribute to a class, structure, enumeration, or interface. You can also apply the attribute to the return value of an XML Web service method.

Every XML document must have a single root element that contains all the other elements. The XmlRootAttribute allows you to control how the XmlSerializer generates the root element by setting certain properties. For example, specify the name of the generated XML element by setting the ElementName property.

Note:
You can use the word XmlRoot in your code instead of the longer XmlRootAttribute.
