C＃導出datagridview選定的行到Word

Question

我在我的表單中有一個DataGridView。我想要做的是如果用戶選擇一行並按Button(button_1)應將來自該行的數據發送到word文檔並根據column[i]替換數字。 現在的代碼如下
問題1當我選擇一行並單擊按鈕時，數據發現並替換了Word文件中的數字，但它取代了所有例如「1」的出現，但我只希望它是做了一次，因爲我想爲每一行做它。 問題2如果用戶選擇多於一行，則僅導出最後選擇的行數據。有任何想法嗎？？

private void button1_Click(object sender, EventArgs e) 
    { 

     string SendPath = ""; 

     if (openFileDialogWord.ShowDialog(this) == DialogResult.OK) 
     { 
      SendPath = (openFileDialogWord.InitialDirectory + openFileDialogWord.FileName).ToString(); 
     } 


     WordDoc(SendPath); 
    } 



    public void WordDoc(string getfilename) 
    { 



     object FileName = getfilename; //The filepath goes here 


     //Create word Application Object 
     Word.Application word = new Word.Application(); 

     //Create word document Object 
     Word.Document doc = null; 

     //Create word Missing Object 
     object missing = System.Type.Missing; 

     object readOnly = false; 
     object isVisible = false; 
     // make visible Word application 
     word.Visible = true; 

     try 
     { 
      doc = word.Documents.Open(ref FileName, ref missing, ref missing, 
      ref missing, ref missing, ref missing, ref missing, ref missing, 
      ref missing, ref missing, ref missing, ref missing, ref missing, 
      ref missing, ref missing, ref missing); 
      doc.Activate(); 




      string Column1; 
      string Column2; 

      foreach (DataGridViewRow rows in dataGridView1.SelectedRows) 
      { 


       Column1 = rows.Cells[1].Value.ToString(); 
       Column2 = rows.Cells[2].Value.ToString(); 

       this.FindAndReplace(word, "1", Column1); 
       this.FindAndReplace(word, "2", Column2); 

      } 

      MessageBox.Show("Complete"); 


     } 
     catch (Exception ex) 
     { 
      MessageBox.Show("Error : " + ex.Message); 
     } 
    } 



    private void FindAndReplace(Word.Application word, object findText, object replaceText) 
    { 
     object matchCase = true; 
     object matchWholeWord = true; 
     object matchWildCards = false; 
     object matchSoundsLike = false; 
     object matchAllWordForms = false; 
     object forward = true; 
     object format = false; 
     object matchKashida = false; 
     object matchDiacritics = false; 
     object matchAlefHamza = false; 
     object matchControl = false; 
     object read_only = false; 
     object visible = true; 
     object replace = 2; 
     object wrap = 1; 
     word.Selection.Find.Execute(ref findText, ref matchCase, 
     ref matchWholeWord, ref matchWildCards, ref matchSoundsLike, 
     ref matchAllWordForms, ref forward, ref wrap, ref format, 
     ref replaceText, ref replace, ref matchKashida, 
     ref matchDiacritics, 
     ref matchAlefHamza, ref matchControl); 
    } 

Answer 1

問題是本部分

對象替換= 2;

我找到了解決辦法，在DreaminCode

替換object replace = 2;與object replace = 1;，它是完美的工作。

如果您有興趣，您可以嘗試我們的第三方GemBox.Document庫以更簡單的方式獲得所需的效果。 與您當前問題的方法有以下幾點：使用硬編碼字符串

1. 「1」，「2」，...作爲佔位符是容易出錯
2. 很難甚至不可能進口與搜索多行&替換時沒有複雜的模板文件
3. 您的應用程序只能在安裝了MS Word的計算機上運行，​​因爲它使用Word Interop。

使用我們的組件，您可以輕鬆地將所有選定DataGridView行的數據導入Word文檔。 下面是一個簡單的C＃代碼如何使用mail merge做到這一點：

 // Create data source for DataGridView. 
     var people = new DataTable() 
     { 
      Columns = 
      { 
       new DataColumn("Name", typeof(string)), 
       new DataColumn("Surname", typeof(string)) 
      }, 
      Rows = 
      { 
       { "John", "Doe" }, 
       { "Fred", "Nurk" }, 
       { "Hans", "Meier" }, 
       { "Ivan", "Horvat" } 
      } 
     }; 

     // Create DataGridView and show it to select rows. 
     var dataGridView = new DataGridView() 
     { 
      DataSource = people, 
      Dock = DockStyle.Fill 
     }; 
     new Form() { Controls = { dataGridView } }.ShowDialog(); 

     // Get selected items which will be used as data source for mail merge. 
     var selectedItems = dataGridView.SelectedRows.Cast<DataGridViewRow>().Select(dgvRow => dgvRow.DataBoundItem).ToArray(); 

     // Create template document which is usually created with MS Word application and loaded with GemBox.Document library. 
     // This code just shows the structure of the template document. 
     var doc = new DocumentModel(); 
     doc.Sections.Add(
      new Section(doc, 
       new Table(doc, 
        new TableRow(doc, 
         new TableCell(doc, 
          new Paragraph(doc, 
           new Run(doc, "Name") { CharacterFormat = { Bold = true } })), 
         new TableCell(doc, 
          new Paragraph(doc, 
           new Run(doc, "Surname") { CharacterFormat = { Bold = true } }))) 
        { 
         RowFormat = { RepeatOnEachPage = true } 
        }, 
        new TableRow(doc, 
         new TableCell(doc, 
          new Paragraph(doc, 
           new Field(doc, FieldType.MergeField, "RangeStart:SelectedPeople"), 
           new Field(doc, FieldType.MergeField, "Name"))), 
         new TableCell(doc, 
          new Paragraph(doc, 
           new Field(doc, FieldType.MergeField, "Surname"), 
           new Field(doc, FieldType.MergeField, "RangeEnd:SelectedPeople"))))) 
       { 
        TableFormat = { PreferredWidth = new TableWidth(100, TableWidthUnit.Percentage) } 
       })); 

     // Execute mail merge. All selected people will be imported into the document. 
     doc.MailMerge.Execute(selectedItems, "SelectedPeople"); 

     // Save document in DOCX and PDF formats. 
     doc.Save(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "SelectedPeople.docx")); 
     doc.Save(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "SelectedPeople.pdf"));
