Open XML SDK 2.0

Question

我正在嘗試關注this教程以創建一個Word文檔模板，我可以使用C＃進行操作。但我總是得到以下錯誤：「名稱'mainPart'在當前上下文中不存在open XML」。我正在使用Open Xml 2.0。

任何想法，我失蹤了什麼？

 using System; 
     using System.IO; 
     using DocumentFormat.OpenXml.Packaging; 

     .... 

     Console.WriteLine("Starting up Word template updater ..."); 

     //get path to template and instance output 
     string docTemplatePath = @"C:\Users\user\Desktop\Doc Offices XML\earth.docx"; 
     string docOutputPath = @"C:\Users\user\Desktop\Doc Offices XML\earth_Instance.docx"; 

     //create copy of template so that we don't overwrite it 
     File.Copy(docTemplatePath, docOutputPath); 

     Console.WriteLine("Created copy of template ..."); 

     //stand up object that reads the Word doc package 
     using (WordprocessingDocument doc = WordprocessingDocument.Open(docOutputPath, true)) 
     { 
      //create XML string matching custom XML part 
      string newXml = "<root>" + 
       "<Earth>Outer Space</Earth>" + 
       "</root>"; 

      MainDocumentPart main = doc.MainDocumentPart; 
      main.DeleteParts<CustomXmlPart>(main.CustomXmlParts); 

      //add and write new XML part 
      //CustomXmlPart customXml = main.AddNewPart<CustomXmlPart>(); 
      CustomXmlPart customXml = mainPart.AddCustomXmlPart(CustomXmlPartType.CustomXml); 
      using (StreamWriter ts = new StreamWriter(customXml.GetStream())) 
      { 

       ts.Write(newXml); 
      } 

      //closing WordprocessingDocument automatically saves the document 
     } 

     Console.WriteLine("Done"); 
     Console.ReadLine();

您需要在第一次訪問它之前創建每個零件。 試試這個：

doc.AddMainDocumentPart()
