SecurityElement.AddAttribute Method

Adds a name/value attribute to an XML element.

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

public void AddAttribute(
	string name,
	string value


Type: System.String

The name of the attribute.

Type: System.String

The value of the attribute.


The name parameter or value parameter is null.


The name parameter or value parameter is invalid in XML.


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.

The following code shows the use of the AddAttribute method to add a name/value attribute to an XML element. This code example is part of a larger example provided for the SecurityElement class.
