c# - 如何将表插入到Word文档中而不是文本标记？

我有DateTable。需要在teplate文档中插入它而不是某些字符集。

我可以用这种方式替换文本到文本(为避免错误，大量的missingObj):

    using Word = Microsoft.Office.Interop.Word;

    Word._Application application;
    Word._Document document;
    Object missingObj = System.Reflection.Missing.Value;
    Object trueObj = true;
    Object falseObj = false;

    private void create_button1_Click(object sender, EventArgs e) {
            application = new Word.Application();
            Object templatePathObj;
            templatePathObj = "template.dot";

            try {
                document = application.Documents.Add(ref  templatePathObj,
                    ref missingObj, ref missingObj, ref missingObj);
            }
            catch (Exception error) {
                document.Close(ref falseObj, ref  missingObj, ref missingObj);
                application.Quit(ref missingObj, ref  missingObj, ref missingObj);
                document = null;
                application = null;
                throw error;
            }

            object strToFindObj = "%%mark%%";
            object replaceStrObj = "text to replace";
            Word.Range wordRange;
            object replaceTypeObj;
            replaceTypeObj = Word.WdReplace.wdReplaceAll;
            for (int i = 1; i <= document.Sections.Count; i++) {
                wordRange = document.Sections[i].Range;
                Word.Find wordFindObj = wordRange.Find;
                object[] wordFindParameters = new object[15] { strToFindObj, missingObj,
                    missingObj, missingObj, missingObj, missingObj, missingObj, missingObj,
                    missingObj, replaceStrObj, replaceTypeObj, missingObj, missingObj,
                    missingObj, missingObj };
                wordFindObj.GetType().InvokeMember("Execute", BindingFlags.InvokeMethod,
                    null, wordFindObj, wordFindParameters);
        }
        application.Visible = true;
    }

我必须更改什么，因此此代码将采用DataTable而不是strToFindObj？

在此示例中，我将Range中的内容替换为ojit_code，包括表，格式等文档的一些碎片。

最佳答案

Target .Net 4.0或更高版本通过COM调用支持命名和可选参数，因此您无需包括所有ref missingObj。请参阅此MSDN文章:Named and Optional Arguments-此功能极大地方便了对COM接口(interface)(例如Microsoft Office Automation API)的调用。



您将不得不遍历DataTables行和Cell来替换Word Document中的DataTable单元，例如:

foreach(var dr in dt.Rows)
{
  foreach (var cell in dr.ItemArray)
  {
    string strToFind = cell.ToString();
    string replaceStr = "replace old value";
    ReplaceTextInWord(@"C:\Temp\template.docx", strToFind, replaceStr);
  }
}

如果您发现使用DataTable太难了，并且想要一个列表(如Dictionary)，那会更容易:

var listOfTextToReplace = new Dictionary<string,string>();
listOfTextToReplace.Add("%%mark%%","text to replace");
foreach(var item in listOfTextToReplace )
{
    string strToFind = item.Key;
    string replaceStr = item.Value;
    ReplaceTextInWord(@"C:\Temp\template.docx", strToFind, replaceStr);
}

这是 ReplaceTextInWord 方法:

using Word = Microsoft.Office.Interop.Word;
Word._Application application;
Word._Document document;
Object missingObj = System.Reflection.Missing.Value;
Object trueObj = true;
Object falseObj = false;

private void create_button1_Click(object sender, EventArgs e) {
   //ReplaceTextInWord("template.dot", "find me", "Found"); <-- Are you sure you want to replace in a Template?
   ReplaceTextInWord(@"C:\Temp\template.docx", "%%mark%%","text to replace");  //I think you want a .DOC or DOCX file
}

private void ReplaceTextInWord(string wordDocFilePath, string strToFind, string replaceStr) {
    application = new Word.Application();
    try {
        //document = application.Documents.Add(ref templatePathObj, ref missingObj, ref missingObj, ref missingObj);
        document = application.Documents.Open(wordDocFilePath);  //You need to open Word Documents, not add them, as per https://msdn.microsoft.com/en-us/library/tcyt0y1f.aspx
    }
    catch (Exception error) {
        document.Close(ref falseObj, ref missingObj, ref missingObj);
        application.Quit(ref missingObj, ref missingObj, ref missingObj);
        document = null;
        application = null;
        throw error;
    }

    for (int i = 1; i <= document.Sections.Count; i++) {
    Word.Range wordRange = document.Sections[i].Range;
    Word.Find findObject = wordRange.Find;
    findObject.ClearFormatting();
    findObject.Text = strToFind;
    findObject.Replacement.ClearFormatting();
    findObject.Replacement.Text = replaceStr;

    object replaceAll = Word.WdReplace.wdReplaceAll;
    findObject.Execute(ref missing, ref missing, ref missing, ref missing, ref missing,
        ref missing, ref missing, ref missing, ref missing, ref missing,
        ref replaceAll, ref missing, ref missing, ref missing, ref missing);
    }
    application.Visible = true;
}
