Document 是 _Document和DocumentEvent2_Event的派生类。

_Document中有一个函数 Microsoft::Office::Interop::Word::_Document::Close([System::Object^], [System::Object^], [System::Object^])

DocumentEvent2_Event中有一个事件响应函数Microsoft::Office::Interop::Word::DocumentEvents2_Event::Close

只有本站会员才能查看附件，请登录

造成对象wordDoc 对“Close”的访问不明确
可以是基 "Microsoft::Office::Interop::Word::_Document" 中的 "Close"
也可以是基 "Microsoft::Office::Interop::Word::DocumentEvents2_Event" 中的 "Close"

编译器错误 C3278“Microsoft::Office::Interop::Word::_Document::Close”接口或纯方法的直接调用将在运行时失败

只有本站会员才能查看附件，请登录

编译器错误 C3278 微软查询
接口或纯方法“method”的直接调用将在运行时失败

注解
对接口方法或纯方法进行了调用，这是不允许的。

示例
以下示例生成 C3278：

程序代码：

// C3278_2.cpp
// compile with: /clr
using namespace System;
interface class I
{
   void vmf();
};

public ref class C: public I
{
public:
   void vmf()
   {
      Console::WriteLine( "In C::vmf()" );
      I::vmf(); // C3278
   }

};

int main()
{
   C^ pC = gcnew C;
   pC->vmf();
}

还是，不明白，代码应该如何修改。。。。
我的程序代码

程序代码：

using namespace System;
using namespace System::IO;
using namespace System::Reflection;
namespace MSWord = Microsoft::Office::Interop::Word;

int main(array<System::String^>^ args)
{
    Object^ path;                              //文件路径变量
    String^ strContent;                        //文本内容变量
    MSWord::Application^ wordApp;               //Word应用程序变量
    MSWord::Document^ wordDoc;                  //Word文档变量
    array<String^>^ WriteDocumen = { "去年今日此门中，\n","人面桃花相映红。\n" ,"人面不知何处去，\n", "桃花依旧笑春风。" };
    path = "C:\\Users\\Administrator\\Desktop\\测试" + DateTime::Now.ToString("yyyyMMddHHmmss") + ".doc";
    wordApp = gcnew MSWord::ApplicationClass(); //初始化
    wordApp->Visible = true;//使文档可见

    //由于使用的是COM库，因此有许多变量需要用Missing.Value代替
    Object^ Nothing = Missing::Value;
    wordDoc = wordApp->Documents->Add(Nothing, Nothing, Nothing, Nothing);//ref Nothing);
    //行间距与缩进、文本字体、字号
    wordApp->Selection->ParagraphFormat->LineSpacing = 16;//设置文档的行间距
    wordApp->Selection->ParagraphFormat->FirstLineIndent = 0;//首行缩进的长度
    //写入普通文本
    strContent = "题都城南庄\n";
    wordDoc->Paragraphs->Last->Range->Font->Size = 22;
    wordDoc->Paragraphs->Last->Range->Font->Name = "方正小标宋简体";
    wordDoc->Paragraphs->Last->Range->Text = strContent;
    wordApp->Selection->ParagraphFormat->Alignment = MSWord::WdParagraphAlignment::wdAlignParagraphCenter;
    Object^ unite = MSWord::WdUnits::wdStory;
    wordApp->Selection->ParagraphFormat->FirstLineIndent = 10;//设置首行缩进的长度
    for each (auto i in WriteDocumen)
    {
        wordApp->Selection->EndKey(unite, Nothing);//将光标移到文本末尾
        wordDoc->Paragraphs->Last->Range->Font->Name = "华文行楷";
        wordDoc->Paragraphs->Last->Range->Font->Size = 48;
        wordDoc->Paragraphs->Last->Range->Text = i;
        wordApp->Selection->ParagraphFormat->Alignment = MSWord::WdParagraphAlignment::wdAlignParagraphCenter;
    }
    wordApp->Selection->EndKey(unite, Nothing); //将光标移动到文档末尾
    //WdSaveFormat为Word 2003文档的保存格式
    Object^ format = MSWord::WdSaveFormat::wdFormatDocument;// office 2007就是wdFormatDocumentDefault
    //将wordDoc文档对象的内容保存为DOCX文档
    wordDoc->SaveAs(path, format, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing, Nothing);
    Object^ saveChanges = MSWord::WdSaveOptions::wdSaveChanges;
    Object^ originalFormat = Type::Missing;
    Object^ routeDocument = Type::Missing;
    //wordDoc->_Document::Close(saveChanges, originalFormat, routeDocument);

}
