本文介绍了一种使用C#和LINQ to XML从XML文件中读取并解析工作流信息的方法。通过加载指定路径下的XML文件，程序能够获取每个工作流的详细属性，并遍历其包含的所有活动节点。

static void GetAllWorkflows()

{

XDocument xdoc = XDocument.Load(@"D:\Document\Workflows.xml");

var workflows = from workflow in xdoc.Descendants("Workflow")

select new

{

Name = workflow.Attribute(

"Name").Value,

Category = workflow.Attribute(

"Category").Value,

Owner = workflow.Attribute(

"Owner").Value,

CreatedOn = workflow.Attribute(

"CreatedOn").Value,

LastUpdatedOn = workflow.Attribute(

"LastUpdatedOn").Value,

LastUpdatedBy = workflow.Attribute(

"LastUpdatedBy").Value,

Children = workflow.Descendants(

"Activity")

};

//Loop through results for every workflow

foreach (var workflow in workflows)

{

Console.WriteLine("WorkflowName: " +workflow.Name+";Category:"+ workflow.Category );

foreach (var activity in workflow.Children)

{

Console.WriteLine(" ActivityName: " + activity.Attribute("name").Value);

Console.WriteLine(" ActivityIsEnabled: " + activity.Attribute("IsEnabled").Value);

}

XML 格式：

<?xml version="1.0" encoding="utf-8"?>
<Workflows>
