如何從XSD/XML自動生成特定.NET語言的類的代碼？

-2

存在一個叫做XSD（XML Schema Definition）的標準，它產生一個XML格式的類定義。生成的類可以使用以下語言：VB, C#, JS, VJS, C++如何從XSD/XML自動生成特定.NET語言的類的代碼？

如何實現從此XML到特定語言的重新創建類？

的XML文件的例子可以如下：

<?xml version="1.0" encoding="utf-8" ?> 
<MyFile VersionProduct="7.0" VersionCreate="7.00" VersionFile="7.00"> 
    <MyTable Size="20"> 
    <StandardTable Type="TXT"> 
     <MyRecord Priority="1" Size="0" Length="350" Weight="270" Age="40" Ref="80"/> 
     <MyRecord Priority="100" Size="0" Length="27080" Weight="27000" Age="40" Ref="80"/> 
    </StandardTable> 
    </MyTable> 
    <MyTable Size="28"> 
    <StandardTable Type="TXT"> 
     <MyRecord Priority="1" Size="0" Length="350" Weight="270" Age="40" Ref="80"/> 
     <MyRecord Priority="100" Size="0" Length="27080" Weight="27000" Age="40" Ref="80"/> 
    </StandardTable> 
    <StandardTable Type="TRT"> 
     <MyRecord Priority="100" Size="0" Length="980" Weight="900" Age="40" Ref="0"/> 
    </StandardTable> 
    </MyTable> 
</MyFile>

***有有更多的內容可以XML文件，我想從自動生成代碼，這個XML只是用來提供一個簡單的例子。

你試過了什麼？任何代碼示例？ 'EnvDTE'＆'VSIX'是你正在尋找的關鍵字。 – Tatranskymedved

@Tatranskymedved @Tatranskymedved我已經找到了解決方案，我只是認爲我會分享，將它作爲答案張貼在 –

以下如果你倒退了，請解釋一下，我會很樂意改變我的問題 –

如果您想要解析XML文件並在.net中創建自動生成的類，那麼您應該使用xsd.exe工具來完成此工作，該工具是Visual Studio中開發工具的一部分。

您將需要打開Dev Command Prompt來運行該工具。 Open Command Prompt from inside Visual Studio

VS 2013命令提示符的默認位置是here，但是這可能會根據安裝位置而改變。

在命令提示符下運行以下命令：

XSD 'yourfilename'.xml

例子：這將自動生成的XML計劃文件' yourfilename'.xsd在目錄文件夾中。

接下來，我們要使用自動創建的XSD文件在我們所選擇的語言自動生成的代碼：

XSD「yourfilename'.xsd /班/語言：VB

示例： 這將從XSD文件創建一個自動生成的.NET類，該類將包含在名爲'yourfilename'.vb的文件中。

然後，您可以簡單地將您的類文件添加到您的項目。我選擇VB，但你可以選擇'CS'，'VB'，'JS'，'VJS'或'CPP'。

這是創建在VB文件中的代碼：

問題和答案都不會提供線索，最終會發生什麼。問題是：問題太短，範圍廣而不清晰（您可以提供xml示例，生成的類等來清楚地顯示*問題*），答案看起來像是兩個非常簡單的步驟的組合（告訴我哪一個更困難）：閱讀有關xsd工具的文檔，並從VS中搜索如何使用它。 – Sinatr

@Sinatr我添加了一個XML示例以及該工具生成的文件內容。我希望這可以讓你更容易理解問題和答案 –
