如何根据VB.NET中的条件将变量设置为值5？ [英] How do I set a variable to have value 5 based on a condition in VB.NET?

问题描述

使用以下xml文档，我需要在vb.net中提供帮助。我想设置一个变量（InCustody），当/ [JuvenileCitationDocument或CitationDocument] / Citation / Citee / InCustodyIndi​​cator = True

我怎么做？

我正在考虑将xml文档放入对象中，例如objXMLInputDoc。该文档（CitationDocumentBatch）将具有或可以具有许多CitationDocuments和/或JuvenileCitationDocuments。

然后，我将查看每个CitationDocument和/或JuvenileCitationDocument的文档。

当我找到CitationDocument或JuvenileCitationDocument的InCustodyIndi​​cator = true（子元素）时，我想设置一个变量为5的值。

我稍后会使用这个值。

  <   CitationDocumentBatch  >  
 <   CitationDocument  >  
 <  事件 >  
 <   Citee  >  
 <   InCustodyIndi​​cator  >  true <   / InCustodyIndi​​cator  >  
 <   / Citee  >  
 <   / Citation  >  
 <   / CitationDocument   
   
    < CitationDocumentBatch  >  
  <   JuvenileCitationDocument    >  
 <  事件 >  
 <   Citee  >  
 <   InCustodyIndi​​cator  >  true <   / InCustodyIndi​​cator  >  
 <   / Citee  >  
 <   / Citation  >  
 <  < span class =code-leadattribute> / JuvenileCitationDocument   
   
  < / CitationDocumentBatch  >

解决方案

为XML创建类（参见VS XML paste special），您可以使用LINQ查询：

 CitationDocumentBatch batch = ...; 
 
  bool  inCustody = 
 batch.CitationDocument.Any（cd = >  cd.Incident.Citee.InCustodyIndi​​cator）|| 
 batch.JuvenileCitationDocument.Any（jd = >  jd.Incident.Citee.InCustodyIndi​​cator）; 
 
如果（inCustody）{ //  等}}  

Using the following xml document, I need help in vb.net. I would like to set a variable (InCustody) to have value = 5 when /[JuvenileCitationDocument or CitationDocument]/Citation/Citee/InCustodyIndicator = True
How do I do this?
I am considering putting the xml document into an object e.g. objXMLInputDoc. This document (CitationDocumentBatch) will have or can have many CitationDocuments and or JuvenileCitationDocuments.
I will then look into this document for each CitationDocument and or JuvenileCitationDocument.
When I find InCustodyIndicator = true (a child element) of a CitationDocument or JuvenileCitationDocument then I want to set a variable to have 5 as it's value.
I will use this value later on.

<CitationDocumentBatch>
	<CitationDocument>
		<Incident>
			<Citee>
				<InCustodyIndicator>true</InCustodyIndicator>
			</Citee>
		</Citation>
		</CitationDocument

	<CitationDocumentBatch>
	<JuvenileCitationDocument >
		<Incident>
			<Citee>
				<InCustodyIndicator>true</InCustodyIndicator>
			</Citee>
		</Citation>
	</JuvenileCitationDocument

</CitationDocumentBatch>

解决方案

Once you create "classes" for your XML (see VS XML paste special), you can use a LINQ query:

CitationDocumentBatch batch = ...;

bool inCustody = 
   batch.CitationDocument.Any( cd => cd.Incident.Citee.InCustodyIndicator ) ||
   batch.JuvenileCitationDocument.Any( jd => jd.Incident.Citee.InCustodyIndicator );

If ( inCustody ) { // etc. }
