Parameters

Dictionary IDictionary<string, string>

ParentNode XmlNode

ListNodeName string

SaveToXml(IDictionary<string, string>, XmlNode, string, string)

Saves Dictionary to ParentNode. A child node with ListNodeName is created to that ParentNode. Then each Dictionary entry becomes a child Node to that ListNodeName Node, with ItemNodeName. FlagName and Value of each Dictionary entry are saved as attributes to that item Node.

public static void SaveToXml(this IDictionary<string, string> Dictionary, XmlNode ParentNode, string ListNodeName, string ItemNodeName)

Parameters

Dictionary IDictionary<string, string>
