导出datagridview选定的行到Word

    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);
    }

问题出在这部分

object replace = 2;

我在DreaminCode找到了解决方案

将object replace = 2;替换为object replace = 1;，工作正常

如果您感兴趣，您可以尝试我们的第三方GemBox。文档库，以更容易的方式获得所需的效果。当前方法的问题如下:

1. 使用硬编码字符串"1"，"2"，…as占位符容易出错
2. 很难甚至不可能导入多行搜索&替换不需要复杂模板文件
3. 你的应用程序只能在安装了Word的计算机上运行，因为它使用Word互操作。

使用我们的组件，您可以轻松地将所有选定的DataGridView行导入到Word文档。下面是一个示例c#代码如何使用邮件合并:

        // 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"));
