OpenXML SDK -Converting C# to C++/CLI

Question

我有用于创建文档的C#代码，我想用C++/CLI语言编写相同的代码。

private void HelloWorld(string documentFileName) 
{
    // Create a Wordprocessing document. 
    using (WordprocessingDocument myDoc =
           WordprocessingDocument.Create(documentFileName, 
               WordprocessingDocumentType.Document)) 
    { 
        // Add a new main document part. 
        MainDocumentPart mainPart = myDoc.AddMainDocumentPart(); 
        //Create Document tree for simple document. 
        mainPart.Document = new Document(); 
        //Create Body (this element contains
        //other elements that we want to include 
        Body body = new Body(); 
        //Create paragraph 
        Paragraph paragraph = new Paragraph(); 
        Run run_paragraph = new Run(); 
        // we want to put that text into the output document 
        Text text_paragraph = new Text("Hello World!"); 
        //Append elements appropriately. 
        run_paragraph.Append(text_paragraph); 
        paragraph.Append(run_paragraph); 
        body.Append(paragraph); 
        mainPart.Document.Append(body); 
        // Save changes to the main document part. 
        mainPart.Document.Save(); 
    } 
}

此外，请建议我任何链接，我可以找到C++/CLI示例的OpenXML软件开发工具包

这是一个直接的翻译：

private:
    void HelloWorld(String^ documentFileName)
    {
        msclr::auto_handle<WordprocessingDocument> myDoc(
            WordprocessingDocument::Create(
                documentFileName, WordprocessingDocumentType::Document
            )
        );
        MainDocumentPart^ mainPart = myDoc->AddMainDocumentPart();
        mainPart->Document = gcnew Document;
        Body^ body = gcnew Body;
        Paragraph^ paragraph = gcnew Paragraph;
        Run^ run_paragraph = gcnew Run;
        Text^ text_paragraph = gcnew Text(L"Hello World!");
        run_paragraph->Append(text_paragraph);
        paragraph->Append(run_paragraph);
        body->Append(paragraph);
        mainPart->Document->Append(body);
        mainPart->Document->Save();
    }

通常应该认为msclr::auto_handle<>比try..finally更惯用，就像std::shared_ptr<>和std::unique_ptr<>在C++中一样。

我想你已经尝试过什么了吧？我不能访问编译器

http://en.wikipedia.org/wiki/C%2B%2B/CLI应该可以帮助您入门。

如果您想知道如何翻译using结构(这是个好问题，如果您已经问过了！)，我建议您使用以下内容(请注意try {} finally { delete ... } idom)

private:

void HelloWorld(String^ documentFileName) 
{ 
    // Create a Wordprocessing document. 
    WordprocessingDocument ^myDoc = WordprocessingDocument::Create(documentFileName, WordprocessingDocumentType::Document);
    try
    {
        // Add a new main document part. 
        MainDocumentPart mainPart = myDoc::AddMainDocumentPart(); 
        //Create Document tree for simple document. 
        mainPart->Document = gcnew Document(); 
        //Create Body (this element contains
        //other elements that we want to include 
        Body body = gcnew Body(); 
        //Create paragraph 
        Paragraph paragraph = gcnew Paragraph(); 
        Run run_paragraph = gcnew Run(); 
        // we want to put that text into the output document 
        Text text_paragraph = gcnew Text("Hello World!"); 
        //Append elements appropriately. 
        run_paragraph->Append(text_paragraph); 
        paragraph->Append(run_paragraph); 
        body->Append(paragraph); 
        mainPart->Document->Append(body); 
        // Save changes to the main document part. 
        mainPart->Document->Save(); 
    } finally
    {
        delete myDoc;
    }   
}

我想重复一遍，我目前没有可用的编译器，所以它可能是粗糙的边缘，但仍然应该提供一些信息
