C＃导出datagridview选定的行到Word

Question

我在我的表单中有一个DataGridView。我想要做的是如果用户选择一行并按Button(button_1)应将来自该行的数据发送到word文档并根据column[i]替换数字。 现在的代码如下
问题1当我选择一行并单击按钮时，数据发现并替换了Word文件中的数字，但它取代了所有例如“1”的出现，但我只希望它是做了一次，因为我想为每一行做它。 问题2如果用户选择多于一行，则仅导出最后选择的行数据。有任何想法吗？？

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

问题是本部分

对象替换= 2;

我找到了解决办法，在DreaminCode

替换object replace = 2;与object replace = 1;，它是完美的工作。

如果您有兴趣，您可以尝试我们的第三方GemBox.Document库以更简单的方式获得所需的效果。 与您当前问题的方法有以下几点：使用硬编码字符串

1. “1”，“2”，...作为占位符是容易出错
2. 很难甚至不可能进口与搜索多行&替换时没有复杂的模板文件
3. 您的应用程序只能在安装了MS Word的计算机上运行，​​因为它使用Word Interop。

使用我们的组件，您可以轻松地将所有选定DataGridView行的数据导入Word文档。 下面是一个简单的C＃代码如何使用mail merge做到这一点：

 // 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"));
