Adds a name/value attribute to an XML element.

Namespace:  System.Security
Assembly:  mscorlib (in mscorlib.dll)

public void AddAttribute(
	string name,
	string value
)

Parameters

name
Type: System.String

The name of the attribute.

Type: System.String

The value of the attribute.

ExceptionCondition
ArgumentNullException

The name parameter or value parameter is null.

ArgumentException

The name parameter or value parameter is invalid in XML.

-or-

An attribute with the name specified by the name parameter already exists.

Names and values in attributes should only contain valid XML attribute characters. XML attribute names must be unique. Use Escape to remove invalid characters from the string.

There is no support for quoted strings, so strings for name/value pairs should not contain quotes or other characters requiring quoting.
